Timex Fitness Sensors

Heart Rate Sensor Speed + Distance Sensor
Watches are for more than keeping time. Digital technology gives your watch the ability to display your heart rate or measure your speed and distance traveled. These functions require the use of external modules that transmit information wirelessly to your watch. This booklet provides instructions for properly setting up, operating and maintaining these devices. Look for the section that is appropriate for the type of device you have.
For information on using your watch, consult the watch instruction booklet.

Heart Rate Monitor

How the Digital Heart Rate Monitor Works
The Heart Rate Monitor is a combination of a Heart Rate Sensor and a sport watch. The Heart Rate Sensor attaches to your chest and measures the electrical signals generated by the heart as it is beating. Using this information, it then calculates your heart rate and transmits it to your watch. You simply glance at the watch during exercise/training to make sure you are in the appropriate heart rate range to maintain or improve your fitness level.

Warning

This is not a medical device and is not recommended for use by persons with serious heart conditions. You should always consult your physician before beginning or modifying an exercise program. Interference with the radio signal, poor contact between your skin and the chest strap, and other factors may prevent accurate transmission of heart rate data.

Maintenance

Rinse Heart Rate Sensor and strap in fresh water to avoid build up of materials that can interfere with the measurement of your heart rate.
How to Use the Digital Heart Rate Monitor
1. Wet the Heart Rate Sensor pads. THIS IS ESSENTIAL for proper operation of the Heart Rate Monitor. 2. Put on the chest strap. Fasten the strap snugly around your chest, just below the breasts. Be sure the transmitter is centered on the chest and is right side Sensor Pads up so the logo can be read by someone facing you. 3. Start the Heart Rate Monitor: Refer to the user manual for your watch for detailed instructions on viewing heart rate data.
Transmitter Battery Life and Replacement
Battery life of the transmitter should exceed two years, based upon using it an hour a day. Greater usage will shorten the battery life. Replace transmitter battery when any of the following occur: The watch no longer receives heart rate information from the chest transmitter when properly worn on the chest. Error messages (COMM ERR, SIGNAL LOST) appear with increased frequency on the display.

Battery Replacement

NOTE: Youll need to have a device (such as a watch) capable of displaying heart rate information to verify that the new
battery has been inserted correctly. Use a coin to open the battery compartment cover (back of transmitter). Insert new battery (CR2032 or equivalent) with +facing you. Push the reset button next to the battery. Use a toothpick or straightened paper clip. Reinstall battery cover. Perform quick test of the unit: 1. Move away from sources of electrical or radio interference. 2. Liberally moisten the Heart Rate Sensor pads and put the chest strap around your chest, securely against your skin. 3. Activate the heart rate monitor function on the watch. 4. Within a few seconds, the heart symbol on the watch display should begin flashing, indicating that the transmitter is active. This confirms that the battery was installed correctly. NOTE: A heart rate value does not need to appear on the display during this test. IF FLASHING HEART DOES NOT APPEAR ON WATCH: Press the reset switch in the battery compartment again and replace the battery cover. Reinstall the battery, and repeat test procedure above.

Speed + Distance Sensor

How the Speed and Distance System Works
The Speed + Distance (S+D) Sensor acquires signals from orbiting GPS (Global Positioning System) satellites to determine your position and changes in position anywhere on the globe. This information is transmitted wirelessly to your watch so that it can compute your speed, pace and distance traveled. For additional information on determining your speed and distance, see the instructions for your watch.

About GPS Lock Times

On first use, the S+D Sensor can take up to 5 minutes or even longer to establish a link with the satellites. After that, the unit typically needs only 15-45 seconds. If you move hundreds of miles from the location where you last used the S+D Sensor or if you leave the S+D Sensor powered up indoors for long periods of time before going outdoors, the search may take longer than expected. For shortest GPS lock times, try to minimize movement while the indicator light is flashing red.

Water Resistance

The Heart Rate Sensor withstands water pressure to 60 p.s.i. See chart at end of booklet for equivalents. WARNING: The Heart Rate Sensor will not display heart rate when operated under water.

Operating the S+D Sensor

For best results, the Sensor needs a clear view of the sky. Press and hold the S+D SENSOR ON/OFF button to turn on the receiver. You should be outdoors in an open area. If the status indicator light glows red immediately (continuously, not flashing), the batteries are exhausted to the point where GPS operation is not possible and the batteries must be replaced. The status indicator light on the S+D Sensor will initially flash red while the S+D Sensor calculates its position relative to the GPS satellites. The text SEARCHING may appear on the watch display if using a compatible Timex watch. The status indicator light will flash green when the S+D Sensor has successfully acquired signals from the satellites. Speed and distance information is now being transmitted to the watch (or other device). To turn off the S+D Sensor, press and hold the S+D SENSOR ON/OFF button for one second. The indicator light will glow red while you are holding the button and then go out, indicating that the S+D Sensor has shut down. The S+D Sensor will shut itself off automatically if any of the following events occur:
The batteries become exhausted. No motion is detected for 15 consecutive minutes. No GPS signals are detected for 15 consecutive minutes.
S+D SENSOR ON/OFF STATUS INDICATOR
Wearing the Speed and Distance S+D Sensor
For best results, strap the S+D Sensor to your upper arm. You may also clip it to your waist. Wear your watch so it is always within 1 meter (about 3 feet) of the S+D Sensor; for best results it should be worn on the same arm as the Transceiver. Any clothing worn over the S+D Sensor must be dry and free of metal.

Wearing the S+D Sensor on your upper arm
Loosen adjustable armband and wrap the Sensor around your upper arm. Pull armband so that it fits snugly around your arm and fasten with the hook and loop closure. If the armband is not attached to the Sensor, rethread with the back of the case removed from the unit (see diagrams at right and below) Make sure the smooth side faces out (hook closure faces back of the case).
Wearing the S+D Sensor on your belt
On the back of the case, lift and turn latch ring a quarter-turn counterclockwise. Remove the back of the case. Remove armband from back of S+D Sensor. Insert clip into slot on mounting bracket (B). Orient clip horizontally or vertically as indicated. Attach mounting bracket to the back of the case. Insert tabs on bottom part of the bracket into vertical slots on either side of the case. (A) Be sure the clip is properly installed.
Resolving S+D Sensor Errors and Error Messages
PROBLEM The S+D Sensor cannot lock onto GPS satellites (Indicator light never changes to flashing green). The GPS S+D Sensor loses signals from the satellites during use. The watch may display a message that the GPS signal is weak. SOLUTION Move to a more open outdoor area. Move away from metal objects. Replace the batteries in the S+D Sensor. NOTE: The system can maintain accuracy for short periods when GPS signals are lost. PROBLEM Watch displays FATAL GPS ERROR message. SOLUTION The S+D Sensor is damaged; contact Timex Customer Service.
S+D Sensor Battery Life and Replacement
The batteries in the S+D Sensor will last approximately 12 hours. The S+D Sensor itself does not indicate the condition of its batteries, except if the batteries are completely exhausted (as noted in the section Operating the S+D Sensor). Instead, this information is broadcast to your watch along with your performance data. Refer to the user manual for your watch for the procedure to check the S+D Sensors battery level.

Replace batteries

Remove the back cover of the S+D Sensor case. Lift and rotate the latch ring a 1/4-turn counterclockwise to release cover. Remove old batteries and insert three new AAA batteries. Observe the +/- markings inside the battery compartment to ensure the new batteries are properly aligned. Replace S+D Sensor cover.
Rinse the S+D Sensor and its strap in fresh water periodically to avoid buildup of materials that can interfere with the measurement of your speed and distance.

All Sensors

Water-Resistance
The level of water-resistance (if any) is marked on the case. See the chart below for equivalents. The S+D Sensor is splash-resistant. If it becomes submerged, remove the back of the case and batteries to let compartment dry.

Welcome

The Timex Bodylink System offers athletes and fitness enthusiasts the unprecedented ability to track, store and analyze several key indicators of personal performance. Using the very latest in digital technology, the Bodylink System is comprised of a network of up to four devices worn on the body that act together as a single information and sport monitoring system. Bodylink Performance Monitor Digital Heart Rate Sensor Speed + Distance Sensor Data Recorder
required by world-class athletes with functions that anyone can use to stay fit for life. Always consult your physician before beginning or modifying any exercise program. Speed + Distance Sensor Utilizing signals from the system of 24 GPS satellites, the Timex Speed + Distance Sensor accurately sends data to the watch to continuously calculate your speed, pace and distance. As part of the Bodylink System, you can now have the performance information at your fingertips to answer the all-important questions, How far? How fast? Data Recorder The Timex Data Recorder functions as the ultimate training log by collecting precise information from your Heart Rate Sensor, Speed + Distance Sensor, or both devices at the same time. Data can be later downloaded to your PC, through the simple USB connection, and teamed with Timex Trainer software to chart your progress. Timex Takes the Guesswork Out of Fitness Improved fitness and athletic performance are as simple as setting a realistic fitness objective and using the Timex Digital Heart Rate Sensor as a personal trainer.
Device(s) enclosed or available separately at www.timex.com.
Bodylink Performance Monitor This sport watch is the essential link to the Bodylink System by providing real-time workout data. It teams with the Digital Heart Rate Sensor or the Speed + Distance Sensor, or it can function simultaneously with both devices to provide comprehensive performance feedback. Digital Heart Rate Sensor As the world leader in sport timing devices, Timex has created a Heart Rate Sensor that offers the digital transmission accuracy
Here is how it works. First, Select a Fitness Objective Thats Right for You Improve Your Fitness Lose Weight and Burn Fat Increase Stamina and Aerobic Endurance Improve Your Fitness Condition Achieve Peak Athletic Performance Second, Select a Heart Rate Exercise Zone Thats Right for You Heart Rate Zone Exercise is the methodology widely used by fitness and sports training professionals for achieving the above fitness objectives. Once set, this Digital Heart Rate Monitor can automatically show you when you are in the Exercise Zone you choose, and signal when you are not. It functions as a personal trainer to help keep your body exercising at an intensity level that can help you achieve your desired Fitness Objective without over- or underexercising. Guidelines for Selecting Your Heart Rate Exercise Zone There are five basic heart rate exercise zones. Simply select a zone that is the fitness goal you want to achieve during a particular exercise. When you begin your exercise, always start out at a lower zone and allow your body to warm up and prepare to work in your target exercise zones. For example, you can warm up in

the Light Exercise zone, spend the majority of your exercise in the Weight Management zone, and then even spend a bit of time in the Aerobic Base Building Zone. The intensity of Zones 4 and 5 is demanding enough that exercise in these zones should be done for limited intervals of a workout and with the guidance of a qualified medical or coaching professional.
FIVE HEART RATE FITNESS ZONES Zone Ideal For Benefit Desired Intensity Level (% Maximum heart rate)
Light Exercise Weight Management Aerobic Base Building Optimal Conditioning Elite Athlete
Maintain Healthy Heart/Get Fit Lose Weight/ Burn Fat Increase Stamina Aerobic Endurance Maintain Excellent Fitness Condition Maintain Superb Athletic Condition
50%-60% 60%-70% 70%-80% 80%-90% 90%-100%
For example, if you want to Lose Weight/Burn Fat: do your favorite exercise at 60%-70% of your maximum heart rate for at least 30 minutes a day, three times a week. The Target Heart Rate Zone Chart (next page) illustrates the different Target Zone values using an age-based method (220 minus your age).
Select which level of condition represents your current physical condition and locate the Lower and Upper Heart Rate Zones for your age from the Target Heart Rate Zone chart. See Target Zone Settings to select the desired Target Zone on your Timex Performance Monitor.
You are ready for higher levels of physical activity when you can work out for this amount of time and heart rate without breathing hard and with minimal soreness. Why Heart Zone Exercise is Widely Used by Fitness/Sports Training Experts. Regular exercise can help keep the heart, lungs and muscles in shape. The heart supplies the lungs and muscles with the oxygenated blood supply needed to exercise. Heart Rate represents the effects of exercise on all parts of the body. Heart Zone Exercise systematically conditions the heart, lungs, and muscles to perform at higher levels so the body can stay in shape. Optimal Conditioning is Simply a Higher Training Habit You do not have to be an athlete to get into optimal shape. Anyone at any age can do this by using cross training to optimal condition. Follow these guidelines:
The latest findings on fitness show anyone at any age can get fit/ stay fit without being fanatic. For the moderate exerciser, staying fit can be as simple as: Exercise 3 Times a Week Exercise 30-45 Minutes Each Time Exercise in Your Appropriate Target Heart Rate Zone
Pick the exercise activities you enjoy or the ones you need for a training program. Train at the appropriate Target Heart Rate for 30 to 60 minutes 3-4 times a week. You will approach optimal condition when you can sustain a complete exercise session without burnout or excessive fatigue or excessive soreness.

The Display

Your Timex Performance Monitor is capable of conveying a lot of information at a glance while occupying only a small space on your wrist. Here is a quick overview of what the symbols on the watch display mean:
TIMER IS RUNNING (ARROW INDICATES TIMER SET TO REPEAT) CHRONO IS RUNNING NIGHT-MODE IS ACTIVATED GPS BATTERY VOLTAGE IS LOW BODYLINK SYSTEM IS ACTIVE, FLASHES DURING DATA OUTAGES AT LEAST ONE ALARM IS ARMED, FLASHES DURING BACKUP PERIOD HOURLY CHIME IS ENABLED
TIP: Press and hold the MODE button for 1.5 seconds to return to Time of Day from any other mode.
Most of the time, the button functions correspond to the labels that are painted on the case. However, there are situations where the button functions have to change to enable you to set the Time of Day, or configure your heart rate target zone. In situations like these, the buttons new function will be indicated by an icon or text visible on the watch display. For example, here is how the buttons function while setting the Time of Day. Notice how the functions of the buttons correspond to the symbols visible on the display:
Here is a second example of the button functions in Lap Data mode. Here the buttons change their functions to enable you to navigate through the stored lap data. Again, the new function of each button is indicated on the watch display.

Next data value

It isnt necessary for you to remember the exact function of the buttons in each mode; simply remember this: When a button function changes from its normal operation, the watch will remind you of the new functionality by displaying the new button function.
Starting the Bodylink System
When using the Performance Monitor, you can view real-time data from a Heart Rate Sensor or Speed + Distance Sensor, or both, in Time of Day, Chrono and Timer. The procedure to do this is the same in all modes, though the data that you can view and their position on the display in each mode will vary. 1. Make sure youre wearing your Heart Rate Sensor or Speed + Distance Sensor, or both, and that they are powered up and functional. 2. Stand at least 6 feet (2 meters) away from any other users of fitness monitor systems and from any source of radio interference such as electrical equipment, power lines, etc. NOTE: Though the Bodylink system has a working range of about 3 feet (1 meter) from the sensors to the watch, for the most reliable operation, make sure that the watch is as close to the sensors as possible when starting the system up. 3. Press and release the DISPLAY button. This tells the watch to look for any Bodylink sensors nearby; it will search for one minute. The antenna icon will appear on the watch display, indicating that the Bodylink system is active.

NOTE: As a convenience, Chrono and Timer will automatically search for Bodylink sensors for fifteen seconds upon entering the mode. 4. When the watch has successfully detected transmissions from the sensors, the watch display will switch to a new format showing some or all of the sensor data, depending on the mode. Time of Day and Timer show the data in the lower line exclusively, while Chrono allows up to three lines of performance data.

Viewing Performance Data

Press and release the DISPLAY button to select the data or combination of data that you wish to view during your workout. For your convenience, a banner showing the names of the information and their position on the display is shown briefly before showing the data itself. Here are a few more things you should know to use the watch effectively: While in the Chrono, press and release SET/FORMAT to swap the positions of the information in the upper and middle display lines. This allows you to view the data most important in the larger middle display line.
If you want to stop monitoring data from your Bodylink sensors, hold the DISPLAY button down until the message HOLD TO SHUT OFF RCVR is displayed on the watch display. Continue holding the DISPLAY button for a few more seconds; the watch will beep indicating that the radio link between the watch and the sensors has been shut down. TIP: If you are already viewing data from one sensor, for example, the Heart Rate Sensor, and you wish to also view data from the Speed + Distance Sensor, simply press and hold the DISPLAY button until the watch emits a short beep and the antenna icon begins flashing. The watch is now searching for a second Bodylink sensor. When it detects this second device, the antenna icon will stop flashing and the display may change to a new format that includes the new information. Press and release the DISPLAY button (as detailed previously) to view various combinations of two sensors data.
SEARCHING (Speed + Distance) The Speed + Distance Sensor has not yet detected enough GPS satellites to calculate your current position, speed and distance. You will not be able to view speed, pace or distance information until the Speed + Distance Sensor locks to a sufficient number of GPS satellites. WEAK GPS SIGNAL (Speed + Distance) The Speed + Distance Sensor has lost its link with the GPS satellites. This message will appear when the Sensor no longer has a clear view of the sky, such as under a dense forest canopy or inside a building; move to a more open area as soon as you can. NOTE: Both the Sensor and the watch employ techniques to maintain reasonable distance accuracy during these periods when GPS tracking is temporarily lost or when the radio link is temporarily interrupted. NO DATA FROM HRM (GPS) The watch is not receiving data from the indicated Sensor. Ensure that the Sensor is not more than 3 ft. (1 m) away from the watch and that it is powered up and functional. The watch will attempt to find the Sensor after this message has been displayed. It is possible that the watch may inadvertently lock to another sensor nearby and not necessarily yours; there-

When using the Speed + Distance Sensor or the Heart Rate Sensor, you can monitor your performance data in the bottom line of the display. Viewing this data is simply a matter of pressing and releasing the DISPLAY button until you see the data that you want: Current Speed Current Pace Overall Distance traveled for your current workout. This data is somewhat dependent on the state of the Chronograph. Please see the complete description for Overall Distance in the Summary Mode section of this manual. Current Heart Rate TIP: If you dont want to view any performance data at all, you may elect to hide these data and view the day of the week instead; this selection is always available when selecting the performance data to view. This setting will be maintained the next time you use the Bodylink system, so it might appear that you are not receiving any sensor data since the day of the week is still visible. Keep this in mind when electing to view the day of week.

Chronograph Mode

The Chronograph (Chrono) mode allows you to record the elapsed time and other information for an event, up to 100 hours. Up to 100 laps may be stored, with the following data for each lap: Lap number, lap time, and split time Average speed, average pace, and distance for each lap (if the Speed + Distance Sensor is in use) Average heart rate (if the Heart Rate Sensor is in use) You can press MODE to switch the watch display to any other
mode, such as Time of Day, while the Chrono is running without disrupting its operation. The stopwatch icon will appear to indicate that the Chrono is running.
A Note About Laps and Splits
Throughout this section we will talk about laps and splits. When describing time, lap time is the time for one segment (lap) of an event. Split time is the total time since the start of the event. We use the term taking a split and taking a lap interchangeably; they both refer to the action that causes the Chrono to stop timing the current segment and start timing a new one. This can be done manually (with the START/SPLIT button) or automatically (when using the Speed + Distance sensor).

Chrono Operation

1. Press START/SPLIT to begin timing. If you are not using any Bodylink sensors, the watch displays lap time, split time, and lap number. If you are using a Heart-Rate Sensor, Speed + Distance Sensor, or both, the watch displays information from those devices, such as heart rate, pace, and distance. 2. Press START/SPLIT while the Chrono is running to take a split. This will store the current lap and split data and start a new lap.
Swap upper & middle display lines To Lap Data/ Hold to go to Time of Day Stop Chrono/ Hold to reset Start Chrono/ Take a split
The watch will show the lap and split time for the lap that you just completed. If you are viewing HRM or Speed + Distance data, the watch will then display the average statistics for the lap (depending on the data you are viewing). The watch will then return to the running Chrono timing the current lap. The watch will store the last 100 laps worth of data. TIP: You may press MODE, SET/FORMAT, or DISPLAY at any time to cancel the lap hold and immediately return to the running Chrono. 3. Press STOP/RESET to stop timing. The display shows the data for the final lap and split, if splits were taken. 4. Press START/SPLIT to resume timing, or press and hold STOP/RESET to reset the display to zero. NOTE: When using the Chrono with either the Speed + Distance or Heart Rate Sensor, the Chrono time and lap information will appear on the display for four seconds after starting, stopping or resetting the Chronograph. During this time, the stopwatch icon will be flashing, and all buttons will function normally. This feature was included to allow you to view the Chrono data for these timing actions even if you have selected to view only performance data (not time data) in the Chrono mode.

Hands-Free Operation

You can configure the Chrono to start when you start moving and stop when you do. In addition, you can have splits taken automatically based on either the distance covered or elapsed time. See the section for Configure mode for the setting details.
When using the Speed + Distance Sensor or the Heart Rate Sensor, you can monitor your performance data. Viewing this data is simply a matter of pressing and releasing the DISPLAY button until you see the data that you want. Refer to inside front cover for a chart that shows the data combinations available in this mode. When viewing performance data, press and release SET/FORMAT to swap the positions of the data in the upper and middle display line. NOTE: Average data values and distance traveled are only accumulated while the Chrono is running.

Lap Data Mode

Lap Data mode allows you to review stored lap information at any time, whether the Chrono is running, stopped or reset. All lap data is erased when the Chrono is started from reset.
scan quickly to a particular lap; release the button to view the data for that lap number. If you were using a Speed + Distance Sensor, or a Heart Rate Sensor, each recalled lap will have three displays of data; the lower line of each will always show the lap number (labeled RCL for Recall). If you were not using any of the sensors, each recalled lap will consist of one display only (lap and split time).

Data Stored For Each Lap

Lap and Split Time The first data stored are the lap and split times for the lap. The lap time is displayed in the upper display line and the split time is displayed in the middle line. Lap Average Speed and Pace Next, you can view the average speed and pace for the current lap, if you are using the Speed + Distance Sensor. These values are based on the distance traveled for the lap and the time for the lap. If you are using the HRM only, you will still see this display, but no performance data will be displayed. Lap Average Heart Rate and Lap Distance Last, the average heart rate for the lap and the distance traveled for the lap are displayed. If you are using the HRM only, the distance traveled data is blank.

Summary Mode

This mode displays a summary of all the aggregate performance data recorded by the watch while the Chrono was running. This mode will not show the data recorded for each lap; refer to the section for Lap Data mode elsewhere in this manual. Like the data in Lap Data mode, when the Chrono is started from reset, all the data in Summary mode are cleared, with the exception of the Odometer data. This can only be cleared manually as described in the following section.

VIEWING THE DATA Press DISPLAY ( ) or STOP/RESET ( ) to navigate through the summary data forward and backward, respectively. Hold the button to scan quickly through the data; release the button to view the specific data for that data group. RESETTING THE ODOMETER While viewing the Odometer value, press and hold START/SPLIT to set this value back to 0.

What Data Is Stored?

INDIGLO Next data value
The following data is available for review in Summary mode. Most of these data rely on information from either the HRM or Speed + Distance Sensor, so if you were not using either of these devices in your workout, most of the displays in Summary mode will show no interesting data. NOTE: The data is not updated while it is being displayed.
Previous data value Hold to clear Odometer
Average Speed The average speed while the Chrono was running, computed by dividing distance traveled by the total Chrono time. Maximum Speed The largest velocity value received by the watch while the Chrono was running.
Average Pace The average pace calculated while the Chrono was running. This value is simply the average speed expressed in terms of minutes per unit distance. Best Pace This is the fastest (smallest) pace value calculated while the Chrono was running. Event Distance The accumulated distance traveled while the Chrono was running. Overall Distance The accumulated overall distance traveled, irrespective of the state of the Chronograph. This distance total will account for any distance you may travel when the Chrono is stopped; the Event Distance value previously described will ignore this distance information. Odometer This works like the trip odometer in your car. It will accumulate distance, irrespective of Chrono usage, until you manually reset it. The odometer value is not cleared automatically between workouts, as is the case with the other distance data, so you can use this value to keep track of your total distance over a period of a week, month, etc. Average Heart Rate The average heart rate calculated while the Chrono is running. Time in Zone The amount of time that the displayed heart rate was within your heart rate target zone. See the section for
Configure mode for detailed instructions for setting your target heart rate zone. Average Heart Rate in Zone This is the average heart rate calculated only using the heart rate values that were within the limits of your target heart rate zone. This data can give you an idea of where your heart rate typically falls when working out in your target zone. Event Time This is equivalent to the Chrono total time. Overall Time This is the total time that the watch has been receiving Speed + Distance data, irrespective of the state of the Chronograph. This data does not take HRM usage into account. GPS Battery Level This display is only accurate while the watch is receiving data from the Speed + Distance Sensor. The voltage level of the batteries is displayed in a bar graph format; when the battery image is empty, the Speed + Distance Sensors batteries are critically low. Consider changing the batteries when the bar graph shows one remaining segment, as there should be at least one hour of battery life left. TIP: The watch will display a battery icon in the upper portion of the watch display to remind you to replace the batteries in the Speed + Distance Sensor.

Timer Mode

Timer mode allows you to set a time from which the watch counts down to zero, making this feature useful for fixed-time events. The Timer can be set to stop, repeat the countdown continuously, or switch to Chrono mode at the completion of the countdown. You can press MODE to switch the watch display to any other mode, such as Time of Day, while the Timer is running without disrupting its operation. The Timer icon will appear to indicate that the Timer is operating.

Timer Operation

1. Press START/SPLIT to start the Timer counting down. 2. Press STOP/RESET to stop the countdown. 3. With the Timer stopped, press START/SPLIT to resume the countdown or STOP/RESET to reset the Timer to the start time. 4. When the timer reaches zero, it sounds an alert. The backlight will also activate to allow you to see the watch in a darkened environment. If the Timer was set to stop, it will be stopped after the alert. If the Timer was set to repeat, it resets to the start time and immediately begins another countdown. It continues repeating until STOP/RESET is pressed. The repeat count is displayed in the lower line of the display. The watch will count up to 99 repetitions, after which it will rollover to 0 and continue. If the Timer was set to start the Chrono, the watch will automatically switch to the Chrono and start it.
Set Timer Stop Timer/ Reset, If stopped Start Timer
To Alarm/ Hold to go to Time of Day
NOTE: This feature will work only if the Chrono is reset when the Timer reaches 0. If the Chrono is not reset at that point, the Timer will simply stop at the end of its countdown and the Chrono will not be started. It is important, therefore, to check that the Chrono is reset before starting the Timer with this action at the end of the countdown.
5. Press SET/FORMAT (SELECT) once again to advance to the ending action setting, then press DISPLAY (+) or STOP/RESET () to choose STOP, REPEAT, or Chrono. 6. Press MODE (DONE) to save your settings and return to Timer. Note that the Timer will be reset after you exit the setting mode.
Viewing Performance Data Setting the Timer
1. Press SET/FORMAT to begin the setting procedure. 2. After the setting reminder display, the watch will display the Timer countdown time with the tens value of the hours digit flashing. Press DISPLAY (+) or STOP/RESET () to increase or decrease the value, respectively. You may hold the keys down to quickly advance through the value. 3. When the value is set correctly, press SET/FORMAT (SELECT) to move to the next digit, in this case the ones value of the hour setting. 4. Continue through minutes and seconds in the same way until the desired time is set. When using the Speed + Distance Sensor or the Heart Rate Sensor, you can monitor your performance data in the bottom line on the display. Viewing this data is simply a matter of pressing and releasing the DISPLAY button until you see the data that you want: Current Speed Current Pace Distance traveled since the Timer was running. If the Timer is not running, this value will not increase. The distance data is cleared when the Timer is started from reset. Current Heart Rate

SPEED/PACE ZONE QUICK SET: Alert type (NONE, SILENT, AUDIBLE) The watch allows you to set speed or pace limits and set the watch to warn you if you are moving too fast or too slowly; this is analogous to the heart rate target zone but based on speed instead. NOTE: If the limits are displayed in terms of speed (i.e. 4 mph or 6 kph) then the watch is checking your current speed against the zone limit settings. If the limits are displayed in terms of pace (minutes and seconds) then the watch is checking your current pace against the zone limit settings.

S + D Settings

These settings affect the watchs response to data from the Speed + Distance Sensor. Here, you may set speed or pace limits, a distance alert and enable or disable smoothing for the speed and pace information.
TIP: You can set the speed and pace limits independently. For instance, you may set the pace limits to help you control your speed for your run and set the speed limits to values that are useful for cycling. Then you can simply switch between the settings when you do each event.
UNITS ARE IN TERMS OF SPEED Fastest Speed
UNITS ARE IN TERMS OF TIME PER DISTANCE Slowest Pace
DISTANCE ALERT QUICK SET: Alert on/off You can set the watch to alert you when you have traveled a specific distance or multiples of that distance. For example, when this setting is set to 1 mile the watch will sound an alert when you have traveled one mile, and then again at two, three and four miles, etc. NOTE: This feature is only enabled when using the Chronograph as it uses the distance accumulated while the Chronograph is running.

Slowest Speed

Fastest Pace
TIP: Use this feature to alert you when youve reached the halfway point in your workout.
When changing the zone limits, the settings are in the following order: Zone type Choose either SPEED or PACE. SLOWEST SPEED (or FASTEST PACE). FASTEST SPEED (or SLOWEST PACE). Alert type If your speed or pace fall outside of the limits you set, the watch will produce either no alert (NO ALRT), an alert indication on the watch display (SILENT), or an alert tone (AUDIBLE).

Alert Interval

Alert Setting
SPEED AND PACE SMOOTHING QUICK SET: Smoothing On/Off These settings determine if smoothing is applied to the displayed speed or pace values. Smoothing is useful if you feel that the displayed speed or pace values appear to be too erratic or jittery, though smoothing may cause the speed or pace values to be slow to respond changes in your speed. Smoothing can be applied separately to speed and pace experiment with these settings to see what combination works best for you.

Q: I am already monitoring data from one Timex sensor and I want to also view data from a second one that I just turned on. What do I do? A: Press and hold the DISPLAY button for about two seconds (you must be in Time of Day, Chrono or Timer modes). The watch will beep and the antenna icon will flash, indicating that the watch is searching for a second Timex sensor. Within a few seconds, the antenna icon should stop flashing and the new data should appear on the watch face (you may have to press and release DISPLAY to select the new data in Time of Day or Timer modes). Q: Occasionally I see NO DATA FROM HRM or NO DATA FROM GPS; what do these messages mean? A: These messages will appear on the watch display when the watch is not receiving signals from the designated sensor. Sometimes these messages pop-up when you might expect them, such as a few seconds after youve shut your Speed + Distance Sensor off, for example. Other times, you might see them during your workout unexpectedly. In that case, the most common causes of these messages are severe radio interference or too much distance between the watch and the sensor. Most of the time, the watch will correct the problem itself, with no action on your part. However, if these messages are becoming a problem, here are a few things to try:
Keep the watch on the same arm as the Speed + Distance Sensor. Check the batteries in the sensors. Low battery voltage will reduce the radio transmission power. Reposition the sensor(s) closer to the watch, if possible. Move away from potential sources of interference. When using the Heart Rate Monitor function, why do I sometimes see a flashing question mark or dash marks next to the heart rate display? These are indications that the Heart Rate Sensor is having difficulty calculating your heart rate. This may be due to: Poor or loose fit of the Sensor on your chest The Sensor being worn upside-down on your chest The conductive material on the underside of the Sensor is not sufficiently moistened How can I reduce the SEARCHING time? The Speed + Distance Sensor will lock to the GPS satellites more quickly if you keep motion during this period to a minimum, and stay in an open area. Also, avoid leaving the Sensor on for long periods of time while indoors. How often is the GPS data calculated and updated? The Speed + Distance Sensor calculates your velocity and distance traveled once per second, and transmits this information to the watch every 3.5 seconds.
