CHAPTER 1 INTRODUCTION 1.1 MAIN FUNCTIONS (MODES)
The Mariner/Yachtsman features the following functions: sailing timer, barometer, compass and watch. These are identified as sail mode [SAIL], barometer mode [BARO], compass mode [COMP] and time mode [TIME] in this manual and also on the display of the instrument. The Regatta features the following functions: compass, chronograph and watch. These are identified as compass mode [COMP]. chronograph mode [CHR] and time mode [TIME].

1.1.1 Backlight Features

The Wristop Computer has an electroluminescent backlight. This is initiated by pressing and holding the [Mode] button in for 2 seconds. The backlight will remain on for 5 seconds. Pressing the [Mode] button during this time will restart the 5 second period, continuing the backlight feature.

1.1.2 Water Resistance

The Wristop Computer is waterproof to a depth of 30m/100ft. Note: The Wristop Computer models are not dive instruments. Buttons should not be operated (put to use) while under water.

1.2 BUTTON FUNCTIONS

Four buttons are used to operate the Wristop Computer: [Mode], [+] (ON/OFF), [-] (Fast Bearing), and [Select].

1.2.1 The [Mode] Button

Is located on the top right of the Wristop Computer. In the main mode level, pressing the [Mode] button allows the user to select or move from one mode or function to the next (TIME, SAIL, BARO, COMP). In the sub mode level, pressing the [Mode] button returns the user to the main mode level. In the setup process, pressing the [Mode] button accepts the changes or preferences. Pressing the button again will return the user to the main mode level.
Pressing the button for 2 seconds activates the backlight feature.

1.2.2 The [+] Button

Is located on the bottom right of the Wristop Computer. In the setup process, pressing the [+] button changes or scrolls the value upward. In the timing functions, this button can act as a start/stop (or On/Off) button.

Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically exit setup. Selecting the units of measurement is complete.
1.5 PRESSURE SENSOR CALIBRATION
WARNING: This is a FACTORY CALIBRATION SETTING. Do not enter this mode. If you enter this mode in error, exit immediately by pressing the [MODE] button to return to the UNI setting mode. Normally there is no need to alter the calibration. If the Pressure Setting Calibration has been altered, you can return the factory setting. Proceed as follows: In the calibration setting mode, scroll the barometric pressure value up or down until text dEF appears. This is the factory setting. Then exit by pressing [MODE].

1.6 CARE AND MAINTENANCE

Perform only the detailed processes discussed in this manual. Do not perform any other service to the Wristop Computer or attempt to open the case or remove the buttons or the bezel. Protect your Wristop Computer from shocks, extreme heat and prolonged exposure to direct sunlight. If not in use, your Wristop Computer should be stored in a clean, dry environment at room temperature. The Wristop Computer can be wiped clean with a lightly moistened (warm water) cloth. Applying a mild soap to the area can clean stubborn stains or marks. Avoid exposing the Wristop Computer to strong chemicals like gasoline, cleaning solvents, acetone, alcohol, adhesives, and paint, as they will damage the units seals, case and finish. Never attempt to take the Wristop Computer apart or service it yourself. Make sure the area around the sensors (backside of the instrument) is kept free of dirt and sand. Never insert any objects into the sensor openings of the Wristop Computer.
1.6.1 Battery Replacement
The Wristop Computer operates on a three-volt lithium cell Type: CR 2430. The maximum life expectancy is approximately 12-18 months.
A low battery-warning indicator is activated when 5-15 percent of the battery capacity is still available. When this occurs we recommend replacement of the battery. Extreme cold weather will activate the low battery-warning indicator. Though the indicator is activated, the battery may not need to be replaced due to this condition. In temperatures above 10C (50F) and the low battery warning indicator is activated, the battery will need to be replaced. Note: Heavy use of the electroluminescent backlight, and compass will significantly reduce the life of the battery. To replace the battery: 1. turn the Wristop Computer to view the backside; 2. insert a coin in the coin slot located on the battery compartment cover; 3. turn the coin counterclockwise to the open position marked on the back of the case; 4. remove the battery compartment cover; 5. remove the old cell from the battery compartment and ensure the O-ring and all surfaces are clean and dry. Do not stretch the O-ring. 6. place the new cell into the battery compartment (negative side down, positive side up); 7. ensure the O-ring is in place to keep the Wristop Computer waterproof and place the battery compartment cover back onto the backside of the Wristop Computer; 8. insert a coin back into the coin slot; and 9. turn the coin clockwise to the close position marked on the back of the case. Note: Battery replacement should be performed with extreme care so as to ensure the Wristop Computer continues to remain waterproof. It is the operators responsibility to take due care to ensure the Wristop Computer remains waterproof. After every battery replacement, it is necessary to calibrate the magnetic sensor. Details on performing this process are found in Calibrating the Compass section of this manual.

The dual time stays the same, even though the time in the main time mode is adjusted. For example, if you set the dual time to show your home time, your home time will always be displayed in this sub mode even though you travel to a different time zone and adjust the time in the main time mode. Note: The dual time sub mode is completely independent and does not effect the alarms or the memory functions. These are dependent on the current local time.
CHAPTER 5 BAROMETER MODE (MARINER AND YACHTSMAN)
The Barometer mode provides the user with: an adjustable unit of measure mbar or inHg; mbar range 300 to mbar, inHg range 8.90 to 32.40; a resolution of 1 mbar or 0.05 inHg;
a one hour interval measuring to estimate barometric trend; a difference measurement function; an automatic 4-day memory of atmospheric pressure for the last 6 hours in 1-hour intervals, thereafter, in 6hour intervals; temperature compensation (temperature does not effect the pressure within the specified temperature range) a temperature range -20 to 60C or -5 to 140F; and a temperature resolution of 1 C or F.
Note: Body heat will effect temperature when the Wristop Computer is worn on the wrist. To achieve an accurate reading remove the Wristop Computer from the wrist and allow at least 15 minutes before reading the temperature. If youve been in the barometer mode for more than 15 minutes with no rate of vertical movement, you should allow 1 hour for the Wristop Computer to adjust the temperature. To acquire a quicker up-date of the temperature, press the [Mode] button 4 times to re-enter the mode. To view and use the Barometer mode: Check the Mode Indicator Bar. If the mode arrow is not on BARO, PRESS the [Mode] button until the arrow is directly below BARO on the bar. In the Barometer mode (Fig. 26): Field 1 displays the current temperature. Field 2 displays the current absolute atmospheric pressure. Field 3 displays the current time. The Outer Circumference graphically displays the atmospheric pressure over 100 millibars or 1 inHg where one complete circle is equivalent to 100 mbar/1 inHg, depending on the unit of measure chosen.

Note: The absolute pressure is the actual pressure in any location at any given time. Where as, sea level pressure is the corresponding pressure at sea level.
5.1 PRESSURE DIFFERENCE MEASUREMENT SUB MODE
In the Barometer mode, PRESS the [Select] button once to enter this sub mode.
In the Pressure Difference Measurement sub mode (Fig. 27): Field 1 displays the change in temperature. Field 2 displays the change in atmospheric pressure. Field 3 displays the current time; to the left of the time is the text differ. The Outer Circumference graphically displays the change in pressure where one full circle equals 100 mbars or 1 inHg.
This sub mode does continue in the background and allows the user to move to other modes and at the users convenience can return to this sub mode to show the current reading.
5.1.1 How to Start the Pressure Difference Measurement
1. PRESS the [Select] button and hold in for 2 seconds. Located in Field 1 is the text SET; located in Field 2, zero will begin to flash (Fig. 28). 2. PRESS the [Mode] button to accept the flashing zero and start the difference measurement. If the user does not desire to begin the difference measurement, PRESS either the [+] or the [-] button to toggle to the current barometric pressure reading, then PRESS the [Mode] button to exit the setup program. Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically exit setup.
5.2 4-DAY MEMORY SUB MODE
In the Barometer mode, PRESS the [Select] button twice to enter this sub mode. This sub mode allows the user to follow changes in pressure that will assist forecasting changes in weather condition (i.e. storms). In the 4-day memory sub mode (Fig. 29): Field 1 displays the day of the week the user is in; Field 2 displays the atmospheric pressure; and Field 3 displays the time and to the left the text memory. The Outer Circumference graphically displays the atmospheric pressure where one full circle equals 100 mbars or 1 inHg.
To view the information compiled in the 4-day memory: PRESS the [-] button to scroll back down in increments of one hour for the first six hours, after that increments are 6 hours. PRESS the [+] button to scroll back up.
Note: Replacing the battery will not erase this information.
5.3 SEA LEVEL PRESSURE SUB MODE
Sea level pressure is pressure relative to sea level where as the pressure read in the main barometric display is absolute pressure in the current location. In the Barometer mode, PRESS the [Select] button three times to enter this sub mode. In the sea level pressure sub mode (Fig. 30): Field 1 displays the text SEA; Field 2 displays the current sea level pressure; and Field 3 displays the current time.

To view and use the Compass mode: Check the Mode Indicator Bar. If the mode arrow is not on COMP, PRESS the [Mode] button until the arrow is directly below COMP on the bar. In the COMPASS mode (Fig. 31): Field 1 displays the cardinal or half-cardinal point. Field 2 displays the bearing in degrees. Field 3 displays the current time. The Outer Circumference graphically displays the North-South arrow where one-lit segment shows North and three-lit segments show South.
The compass display is active for 45 seconds at a time. After this, the compass enters sleep mode and an --- indicator appears in the field 2. Reactivate the compass by pressing the [-] button. The Mariner provides a bubble level for the user to achieve a precise reading within 3 degrees. The user centers the liquid bubble to ensure the Wristop Computer position is level and takes a reading. Note: Compass readings should be performed away from objects possessing sources of magnetism. Avoid buildings, large metal objects, power lines, loudspeakers, electric motors etc. Always take bearings in the open air, not inside tents, caves, or other shelters.
6.1 BEARING TRACKING SUB MODE
The user can select to change from the cardinal point mode to the bearing track mode and utilize the bearing lock feature in this mode for tracking purposes (Fig. 32). In the compass main mode: 1. PRESS the [Select] button and hold in for 2 seconds. Located in Field 1, OFF will begin to flash and the field 2 shows the text bEA (bearing) (Fig. 33). 2. PRESS either the [+] or the [-] button to change the setting between OFF and ON. 3. At the selection desired, PRESS the [Select] button to move to the next setting. Located in Field 2, the actual bearing in degrees will begin to flash (Fig. 34). 4. Turn the Wristop Computer to the desired direction. Lock the bearing displayed by pressing the [-] button. 5. Adjust the locked bearing, if necessary by pressing the [Select] button and then adjusting the value with the [+] and [-] buttons. 6. At the desired bearing to track, PRESS the [Mode] button to accept the changes and exit the setup program. Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically exit setup.
6.2 DECLINATION ADJUSTMENT SUB MODE
The Wristop Computer allows the user to compensate the difference between true north and magnetic north. This process is accomplished by adjusting the declination, resulting in the user obtaining correct compass readings. In the Compass mode, PRESS the [Select] button once to enter this sub mode. In the Declination Adjustment sub mode (Fig. 35): Field 1 displays the declination direction OFF where OFF = no declination; W = West; E = East. Field 2 displays declination in degrees. Field 3 displays the text dEC.

6.2.1 Setting the Local Declination
1. PRESS the [Select] button and hold in for 2 seconds. Located in Field 1, OFF will begin to flash. 2. PRESS either the [+] or the [-] button to change the declination direction in Field 1. 3. At the direction desired, PRESS the [Select] button to move to the next setting. Located in Field 2, the degrees will begin to flash. 4. PRESS the [+] button to scroll the degrees upward or PRESS the [-] button to scroll the degrees downward. 5. At the degrees desired, PRESS the [Mode] button to accept the changes and exit the setup program. Note: If the user does not press any button for 1 minute in the setup mode, the display will automatically exit setup. Local Declination is now set.
6.3 CALIBRATING THE COMPASS
A compass calibration should be done when the Wristop Computer is subject to close proximity of magnetic sources, extreme cold weather, every time the battery is replaced or suspected that other environmental conditions have effected the compass readings. Note: We also recommend calibrating the compass before using the compass the first time and every time leaving for a hike where the compass will be used. To begin the calibration: 1. PRESS the [Select] button twice when in the main compass mode. Field 1 displays the text CMP. Field 3 displays the text CAL (Fig. 36). 2. PRESS the [Select] button and hold in for 2 seconds. Located in Field 2, the text PUSH will begin to flash (Fig. 37). 3. PRESS the [-] button to start calibration. 4. In Field 2, 360 appears and the Outer Circumference displays all segments lit (Fig. 38). When this occurs, hold the Wristop Computer level and start to slowly turn the device around a full circle in a level position. The
direction of turning does not matter. The lit segments will be turned off as the turning proceeds. When the first full circle is completed, the instrument will inform the user within one minute of whether the calibration was successful displaying the text dOnE in Field 2 (Fig. 39) or if the process needs to be repeated displaying PUSH and - in Field 2. Note: The user may need to perform the rotating of the compass more than twice around for the calibration to be completed. Note: If the text FAIL appears in Field 2 (Fig. 40), the battery should be removed and put back in before trying to proceed with the calibration process. The removal of the battery will reset the unit. 5. Once the calibration is successful, PRESS the [Mode] button to accept the process and exit the calibration mode. Note: It is important to hold the Wristop Computer level during the calibration process to ensure accuracy. The compass calibration is complete.

CHAPTER 7 FREQUENTLY ASKED QUESTIONS 7.1 GENERAL
7.1.1 Is the Wristop Computer waterproof?
Yes, it is waterproof to a depth of 30 meters (100 ft). Rain and other normal exposure to water will not effect its operation. You can swim wearing your Wristop Computer. However, the Wristop Computer is NOT a diving device.
7.1.2 How long will the battery last?
All users employ the product in different ways. Battery life depends mainly on how much the backlight and the compass are used. The low-battery warning symbol appears on the display when 5 to 15 percent of battery capacity remains. This should give the user plenty of time to safely change the battery.
7.1.3 What do the segments on the circumference mean?
In the Barometer mode, one full circle equals 100 mbar or 1 inHg, and the segments indicate the pressure over
a full hundred mbar or over a full inHg. When using the difference measurement function of the barometer, the segments indicate the change in atmospheric pressure either to the right if the pressure has risen or to the left if the pressure has dropped. In the main Compass mode, the segments indicate the North, i.e. the one segment indicates North and the three segments point South. If you have set the compass to track a certain bearing, the segments on the circumference indicate the difference between the direction in which you want to go and your actual bearing.
7.1.4 Why do the segments on the circumference go to the left (counterclockwise)?
Normally, they always go to the right (clockwise) from the 12-noon position. You are in the difference measurement mode and your unit is showing a decreasing value. In normal mode, the segment display increases clockwise, but if you are in a mode that shows you differences, all decreasing values go counterclockwise from the center position, and all increasing values go clockwise. So, it is minus to the left (counterclockwise), and plus to the right (clockwise).
7.1.5 Why is there a symbol above the Mode Indicator Bar and what does it mean?
The symbol indicates that one, two, or three daily alarms are activated.

7.2 TIME

7.2.1 Why do the segments on the circumference increase and decrease when I am in the Time mode?
The main function of the segments is related to the Compass mode, where a division into 36 segments is necessary due to the 360-degree scale of a compass. In the Time mode, the segments show the advancement of seconds. Because the number of seconds differs from the number of degrees, it is impossible for the segments to be consecutively lit up; they now light up or extinguish, thereby marking the passing of every second.

7.2.2 What is the longest time I can set in the timer?
The maximum range of the countdown timer is 23 hours 59 minutes and 59 seconds.

7.3 BAROMETER

7.3.1 What is the little box on the top left of the display?
It is the barometric trend indicator that shows the general direction of weather changes. The display is based on barometer measurements for the last 6 hours.
7.3.2 Does the Wristop Computer show future trends in weather conditions?
No, the Wristop Computer continually accumulates data on barometric pressure existent within a 3 to 6 hour window and displays general barometric trends in weather based on the accumulated data.
7.3.3 What does absolute pressure and relative pressure mean?
Absolute pressure is the actual pressure in any location at any given time. Relative pressure on the other hand equals the corresponding pressure at sea level for a certain altitude that you are at. For example, if you are at an altitude of 1,000 m/3,300 ft the absolute pressure normally is around 900 mbar/26.60 inHg. The relative pressure at sea level would then be around 1,013 mbar/29.90 inHg.
7.3.4 Is the Wristop Computer temperature compensated?
Yes, the Wristop Computer is temperature compensated, which means that for the temperature range specified (-5 to +140F/-20 to +60C), the instrument will show accurate pressure. Within this range, the temperature has no effect on the atmospheric pressure reading. Temperature compensation does not, however, mean that the temperature reading isnt at all effected by body heat. Body heat will affect the temperature reading, and to get the correct temperature reading of the environment remember to take the Wristop Computer off your wrist and wait about 15 minutes for it to stabilize and show the correct temperature of the surroundings.

7.4 COMPASS

7.4.1 What is the purpose of the rotating outer bezel?
The purpose of the rotating bezel is that people can use the instrument as a regular base plate compass if they want to, and use the bezel to e.g. indicate North when in the bearing tracking mode or leaving the compass display for another mode.
7.4.2 Where do I find the correct declination for my area so I can set my Wristop Computer?
Local declination, either E or W, is usually marked on maps with either one-degree or half-degree accuracy.
