More about tones

Polyphony This piano can play up to 64 notes at the same time. Also note that some of the tones offer only 32-note polyphony (GRAND PIANO, MELLOW PIANO, ELEC PIANO 1, HARPSICHORD, STRINGS). Touch Response The touch response feature of this piano causes the volume of the tones and the sound of the tones themselves to change slightly in accordance with how much pressure you apply to the keyboard, just like with an acoustic piano. Touch response affects the HARPSICHORD tone only slightly, because the original musical instrument normally produces the same sound, no matter how much pressure is applied. Digitally Sampled Tones The tones of this piano are produced using digitally recorded samples of actual musical instruments. Not all of the instruments, however, can produce tones across the entire range played by this piano (A0 through C8). In such a case, digital recordings are used for the range that actually can be produced by the original instrument, and synthesized tones are used for notes that cannot be produced naturally. Because of this, you may notice very slight differences between natural notes and synthesized notes in sound quality and in results produced when using effects. These differences are normal and do not indicate malfunction.
While holding down the CONTROL button, press the keyboard key that corresponds to the digital effect you want to select.
A note does not sound when you press a keyboard key while holding down the CONTROL button.
Power on effect settings The table below shows the effect settings that are assigned to each tone whenever you turn on the digital piano power.

The above digital effect settings can be changed after you turn on power.
Selecting a tone automatically selects the digital effects currently assigned to it. Changes you make to digital effect settings are assigned to the currently selected tone only. Digital effect settings remain in effect until you turn off the digital piano power. Demo tunes have their own digital effect settings, which are automatically selected whenever you select a demo tune.

F4: + (raises the pitch) E4: (lowers the pitch)
To adjust the tuning of the piano Adjust the tuning as described below.
While holding down the CONTROL button, press keyboard key E4 () to lower the tuning or F4 (+) to raise it. Each press of a key changes the tuning by about 0.8 cents (1/128 semitone).
Holding down the CONTROL button and pressing keyboard keys E4 () and F4 (+) at the same time returns tuning to the standard A4 = 440.0Hz. * 100 cents is equivalent to one semitone.

What is MIDI?
The letters MIDI stand for Musical Instrument Digital Interface, which is the name of a worldwide standard for digital signals and connectors that makes it possible to exchange musical data between musical instruments and computers (machines) produced by different manufacturers. MIDI compatible equipment can exchange keyboard key press, key release, tone change, and other data as messages. Though you do not need any special knowledge about MIDI to use this digital piano as a stand-alone unit, MIDI operations require a bit of specialized knowledge. This section provides you with an overview of MIDI that will help to get you going. *1 Keyboard play and memory playback data can be sent as MIDI data. Demo tunes cannot be sent as MIDI data. *2 A device that contains memory storage for MIDI data. Some MIDI sequencers feature external storage capabilities, which let you record a virtually unlimited number of tunes.

MIDI Connections

Two MIDI cables, one for sending and one for receiving, are required for two-way recording and playback capabilities with a connected MIDI sequencer or other device.
What you can do with MIDI MIDI Channels

MIDI cable: MK-5

Sender

IN Receiver

MIDI musical instrument MIDI sound module MIDI sequencer Other MIDI device
What you play on the digital piano can be sent to the connected device as MIDI messages* 1. The connected device sounds notes in accordance with the messages it receives. MIDI messages*1 can be sent from the digital piano to a commercially available MIDI sequencer*2 for recording.
MIDI allows you to send the data for multiple parts at the same time, with each part being sent over a separate MIDI channel. There are 16 MIDI channels, numbered 1 through 16, and MIDI channel data is always included whenever you exchange data (key press, pedal operation, etc.). Both the sending machine and the receiving machine must be set to the same channel for the receiving unit to correctly receive and play data. If the receiving machine is set to Channel 2, for example, it receives only MIDI Channel 2 data, and all other channels are ignored. This digital piano is equipped with multi-timbre capabilities, which means it can receive messages over all 16 MIDI channels and play up to 16 parts at the same time. Keyboard and pedal operations performed on this digital piano are sent out by selecting a MIDI channel (1 to 16) and then sending the appropriate message.

The tone GRAND PIANO is automatically assigned to all channels whenever you turn on the digital piano power.

Local Control

General MIDI

The General MIDI System is a set of specifications for sound generating devices agreed upon by world MIDI manufacturers. These specifications were developed to allow the creation of music data that is not limited to specific equipment makers and models. Among other things, General MIDI defines the tone number sequence and the number of MIDI channels that can be used. Any device equipped with a sound source that supports General MIDI is able to produce sounds of similar nuances, regardless of the manufacturer or model. The Type 2 program change numbers of this digital piano assign program numbers to tones so they comply with the General MIDI System. Type 2 program change numbers make it possible to receive General MIDI System data from a connected sequencer or other device, and play it using the digital pianos tones. Tone switching is performed only when a program number that corresponds to any of the digital pianos non-bass tones is received. No tone switching is performed when any other program number is received. The table on page E-23 shows the program number assignments for Type 1 and Type 2.

When Local Control is on (the normal setting), anything played on the keyboard is sounded by the internal sound source and simultaneously output from the MIDI OUT terminal. When off, anything played on the keyboard is output from the MIDI OUT terminal only, without being sounded by the sound source. Local Control can be turned off when you are using the digital piano as the sound source of a connected sequencer or other device, and you want to guard against sound being produced should the digital piano keyboard be pressed accidentally.
To turn Local Control on and off
While still holding down the CONTROL button, switch Local Control on and off by pressing one of the keyboard keys illustrated below.

F 5 (black key): OFF

C4 G5: ON
A note does not sound when you press a keyboard key while holding down CONTROL.
Note that no sound will be produced from the digital pianos speakers if you press the keyboard while Local Control is turned off. Local Control is turned on automatically whenever you turn on the digital piano power or play a demo tune.

MIDI Data Notes
This section provides details about the MIDI data this digital piano sends and receives. You can also find further technical information in the MIDI Data Format and MIDI Implementation Chart* at the end of this Users Guide. * The MIDI Implementation Chart is a standard format summary of how data is transferred between this digital piano and a connected MIDI device.
Keyboard Data (Note On, Note Off, Note Number, Velocity)
The following four types of keyboard data can be sent and received.
Data Note On Note Off Note Number Velocity Meaning Keyboard key is pressed. Keyboard key is released. Which key is pressed. Pressure applied
Tone Change Data (Program Change)
Whenever you change the tone on the digital piano, tone change data (Program Change) is also sent out as MIDI data. Conversely, receipt of a Program Change from a connected MIDI device causes the digital piano to change to the applicable tone. See Program Change Number Settings on page E-23 for details.
Pedal and Effect Operation Data (Control Change and Universal System Exclusive Message)
Control Change is used to send and receive data about damper, soft, and sostenuto pedal* depress and release operations, as well as data about digital effects. * You can connect up to two pedals to this digital piano. You can also specify either soft or sostenuto as the effect of the pedal connected to the SOFT/SOSTENUTO jack. Pressing a pedal connected to the SOFT/SOSTENUTO jack sends data that corresponds to the effect (soft or sostenuto) currently selected for the pedal.

Applications

The built-in sensors of this watch measure direction, barometric pressure, temperature and altitude. Measured values are then shown on the display. Such features make this watch useful when hiking, mountain climbing, or when engaging in other such outdoor activities.

About This Manual

Sensor
If the digital display of the watch is blank.
If the PS indicator is on the display (either flashing or steady), it means that the watchs Power Saving function has turned it off to conserve power. Power Saving automatically turns off the display and enters a sleep state whenever the watch is left for a certain period where it is dark. The initial factory default setting is Power Saving on. The watch will recover from the sleep state if you move it to a well-lit area, if you press any button, or if you angle the watch towards your face for reading. It can take up to two seconds for the display to turn on. See Power Saving for more information.
Button operations are indicated using the letters shown in the illustration. Each section of this manual provides you with the information you need to perform operations in each mode. Further details and technical information can be found in the Reference section.

During measurement, the watch displays an angle value, a direction indicator, and four direction pointers, which change dynamically when the watch is moved. After measurement is complete, the angle value, direction indicator, and four direction pointers are frozen in accordance with the last measurement. The indicator flashes on the display while a measurement is in progress. Note Note that taking a measurement while the watch is not horizontal (in relation to the horizon) can result in large measurement error. The margin of error for the angle value is 11 degrees. If the indicated direction is northwest (NW) and 315 degrees, for example, the actual direction can be anywhere from 304 to 326 degrees. Any ongoing direction measurement operation is temporarily paused while the watch is performing an alert operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while the watchs backlight is turned on (by pressing L). The measurement operation resumes for its remaining duration after the operation that caused it to pause is finished.

1. Enter the Digital Compass Mode. 2. Place the watch on a flat surface or, if you are wearing the watch, make sure that your wrist is horizontal (in relation to the horizon). 3. Point the 12 oclock position of the watch in the direction you want to measure. 4. Press B to start a Digital Compass measurement operation. After about two seconds, the direction that the 12 oclock position of the watch is pointing appears on the display. Also, four pointers appear to indicate magnetic north, south, east, and west. After the first reading is obtained, the watch continues to take direction readings automatically each second, for up to 20 seconds.
Barometric Pressure Indicators
The watchs barometric pressure indicators graphically show you whether the barometric pressure for up to the last 15 hours has been rising, holding steady, or falling. Since changes in barometric pressure signal changes in the atmosphere, you can predict upcoming weather with reasonable accuracy by looking at the current tendency of barometric pressure. The barometric pressure indicator display area of the watch has three lines: top, middle, and bottom. The location of each indicator tells you whether barometric pressure is rising, steady, or falling.
Rise greater than 3hPa from previous reading Within 2hPa of previous reading Fall greater than 3hPa from previous reading

NN E NE ENE

How to Interpret Barometric Pressure Indicators
The rightmost indicator is the newest indicator, the leftmost indicator is the oldest indicator.
Rising pressure generally means improving weather. Falling pressure generally means deteriorating weather.
The locations of the indicators, not their pattern, indicates barometric pressure tendencies. A series of multiple indicators in the top line of the barometric pressure indicator display area indicates a series of rising pressure readings. It does not indicate steady pressure at a high level. A series of multiple indicators in the bottom line of the barometric pressure indicator display area indicates a series of falling pressure readings. It does not indicate steady pressure at a low level. A movement of indicators from the top line to the middle line does not indicate falling pressure, and a movement of indicators from the bottom line to the middle line does not indicate rising pressure. A move to the middle line indicates that the current pressure measurement is relatively unchanged (within 2hPa) from the previous measurement. Rising pressure is not indicated until an indicator appears in the top line, and falling pressure is not indicated until an indicator appears in the bottom line. Steady pressure is indicated by a series of indicators in the middle line. Notes Though you can configure the watch to display barometric pressure in units of hPa or inHg, the barometric pressure indicator positions are always determined based on 3 hPa changes in barometric pressure. No indicator is plotted if a measurement operation cannot be performed due to sensor malfunction, low battery power, because of the watch is in the function sleep state, or any other reason.

Pressing D causes the measurement operation to restart from the beginning of the cycle described above. Altitude is displayed in units of 5 meters (20 feet). The measurement range for altitude is 700 to 10,000 meters (2,300 to 32,800 feet). The measured altitude may be a negative value in cases where there is a reference altitude value set or because of certain atmospheric conditions. The displayed altitude value changes to xxxxx meters (or feet) if a measured altitude falls outside the measurement range. The altitude value will be displayed again as soon as the measured altitude is within the allowable range. You can change the unit of measurement for the displayed altitude values between meters (m) and feet (ft). See To change the altitude unit.

Altitude Indicator

In the Altimeter Mode, the altitude indicator shows the current altitude reading in meters (m). As shown in the illustration below, the altitude indicator is divided into two zones: one for 0 to 999 meters, and one for 1000 to 10,000 meters. Though you can specify either meters or feet for the watchs altitude measurements, the altitude indicator always shows altitude in meters.
1000+ meter zone 0-999 meter zone
The above altitude indicator indicates an altitude of approximately 4,340 meters. The 0-999 meter zone starts from the 12 o'clock position (0 meters), and indicates altitudes in 20-meter units. The 1000+ meter zone indicates altitudes in 1000-meter units.

How the Altimeter Works

With the Preset Values (No Reference Altitude) The watch measures the air pressure at your current location and uses the built-in ISA values to convert it to the equivalent altitude. With a Reference Altitude If you set a reference altitude, the watch uses that value when calculating altitude based on air pressure. To determine the height of a tall building, set the reference altitude to 0 on the ground floor. Note, however, that you may not be able to get a good reading if the building is pressurized or air-conditioned. When mountain climbing, you can set the reference value in accordance with a marker along the way or altitude information from a map. After you do this, the altitude readings produced by the watch will be more accurate than they would be without a reference altitude.
Setting a Reference Altitude
After you set a reference altitude, the watch adjusts its air-pressure-to-altitude conversion calculation accordingly. The altitude measurements produced by this watch are subject to error caused by changes in air pressure. Because of this, we recommend that you update the reference altitude whenever one is available during your climb.

About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on, whenever you position your wrist as described below in any mode. Note that this watch features a Full Auto EL Light, so the auto light switch operates only when available light is below a certain level. It does not turn on the backlight under bright light. Moving the watch to a position that is parallel to the ground and then tilting it towards you more than 40 degrees causes the backlight to turn on. Wear the watch on the outside of your wrist.

Parallel to ground

You can set five independent daily alarms. When an alarm is turned on, the alarm tone sounds when the alarm time is reached. You can also turn on an Hourly Time Signal, which will cause the watch to beep twice every hour on the hour. The alarm number (ALx1 through ALx5 ) indicates an alarm screen. :00 is shown for the alarm time when the Hourly Time Signal screen is on the display. When you enter the Alarm Mode, the data you were viewing when you last exited the mode appears first. All of the operations in this section are performed in the Alarm Mode, which you enter by pressing C.

Warning! Always make sure you are in a safe place whenever you are reading the display of the watch using the auto light switch. Be especially careful when running or engaged in any other activity that can result in accident or injury. Also take care that sudden illumination by the auto light switch does not surprise or distract others around you. When you are wearing the watch, make sure that its auto light switch is turned off before riding on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto light switch can create a distraction, which can result in a traffic accident and serious personal injury.
To turn the auto light switch on and off
In any mode except while a setting is flashing on the display, hold down L for about two seconds to toggle the auto light switch on ( displayed) and off ( not displayed). The auto light switch on indicator ( ) is on the display in all modes while the auto light switch is turned on. The auto light switch turns off automatically whenever battery power drops to Level 3. The backlight may not light right away if you raise the watch to your face while a barometric pressure or altitude measurement operation is in progress. The auto light switch is always disabled, regardless of its on/off setting, when any one of the following conditions exists.

Sea Precautions Concerning Simultaneous Measurement of Altitude and Temperature Though you can perform altitude and temperature measurements at the same time, you should remember that each of these measurements requires different conditions for best results. With temperature measurement, it is best to remove the watch from your wrist in order to eliminate the effects of body heat. In the case of altitude measurement, on the other hand, it is better to leave the watch on your wrist, because doing so keeps the watch at a constant temperature, which contributes to more accurate altitude measurements. The following describes what you should do to give priority to either altitude or temperature. To give altitude measurement priority, leave the watch on your wrist or in any other location where the temperature of the watch is kept constant. To give temperature measurement priority, remove the watch from your wrist and allow it to hang freely from your bag or in another location where it is not exposed to direct sunlight. Note that removing the watch from your wrist can momentarily affect pressure sensor readings.

Power Supply

This watch is equipped with a solar cell and a special rechargeable battery (secondary battery) that is charged by the electrical power produced by the solar cell. The illustration shown below shows how you should position the watch for charging. Example: Orient the watch so its face is pointing at a light source. The illustration shows how to position a watch with a resin band. Note that charging efficiency drops when any part of the solar cell is blocked by clothing, etc. Normally, you should try to keep the watch outside of your sleeve as much as possible. Charging is significantly reduced if the face is only partially covered.

Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause rechargeable battery power to run down. Be sure that the watch is normally exposed to bright light whenever possible. This watch uses a special rechargeable battery to store power produced by the solar cell, so regular battery replacement is not required. However, after very long use, the rechargeable battery may lose its ability to achieve a full charge. If you experience problems getting the special rechargeable battery to fully charge, contact your dealer or CASIO distributor about having it replaced. Never try to remove or replace the watchs special battery yourself. Use of the wrong type of battery can damage the watch. All data stored in memory is deleted, and the current time and all other settings return to their initial factory defaults whenever battery power drops to Level 4 and when you have the battery replaced. Turn on the watchs Power Saving function and keep it in an area normally exposed to bright light when storing it for long periods. This helps to keep the rechargeable battery from going dead.

Recovery Times The table below shows the amount exposure that is required to take the battery from one level to the next. Approximate Exposure Time Exposure Level Level 4 Level 3 Level 2 Level 1 (Brightness)

(Charge Soon Alert)

The flashing CHARGE indicator at Level 3 tells you that battery power is very low, and that exposure to bright light for charging is required as soon as possible. At Level 4, all functions are disabled, memory contents are cleared, and settings return to their initial factory defaults. Functions are enabled once again after the rechargeable battery is charged, but you need to set the time and date after the battery reaches Level 3 (indicated by the L indicator) from Level 4. You will not be able to set any of the other settings until the battery reaches Level 2 (indicated by the M indicator) after dropping to Level 4. Display indicators reappear as soon as the battery is charged from Level 4 to Level 3. Leaving the watch exposed to direct sunlight or some other very strong light source can cause the battery power indicator to temporarily show a reading that is higher than the actual battery level. The correct battery level should be indicated after a few minutes. If you use the backlight or alarms a number of times during a short period, RECOV. appears on the display and the backlight, alarm, countdown timer alarm, hourly time signal, and sensor operations become disabled until battery power recovers. After some time, battery power will recover and RECOV. will disappear, indicating that the above functions are enabled again. Recover indicator Even if battery power is at Level 1 or Level 2, the Digital Compass Mode, Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufficiently. This is indicated by RECOV. on the display. If battery power goes low while a measurement operation is in progress, the value produced by the last successful measurement operation remains on the display. Attempting to perform a sensor operation in the Digital Compass Mode will cause xxx to appear on the display. In other sensor modes, the display will go blank. In the case of temperature, the last successfully measured value will appear on the display. If RECOV. appears frequently, it probably means that remaining battery power is low. Leave the watch in bright light to allow it to charge.

Charging Precautions

Certain charging conditions can cause the watch to become very hot. Avoid leaving the watch in the areas described below whenever charging its rechargeable battery. Also note that allowing the watch to become very hot can cause its liquid crystal display to black out. The appearance of the LCD should become normal again when the watch returns to a lower temperature. Warning! Leaving the watch in bright light to charge its rechargeable battery can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods. On the dashboard of a car parked in direct sunlight Too close to an incandescent lamp Under direct sunlight

Reference

This section contains more detailed and technical information about watch operation. It also contains important precautions and notes about the various features and functions of this watch.

Auto Return Features

The watch automatically returns to the Timekeeping Mode if you do not perform any button operation for two or three minutes in the Data Recall, Alarm, Digital Compass, or Barometer/Thermometer Mode. If you do not perform any button operation while in the Altimeter Mode, the watch automatically returns to the Timekeeping Mode after nine or 10 hours. If you leave a screen with flashing digits on the display for two or three minutes without performing any operation, the watch automatically exits the setting screen. Holding down C for about one second while in the Stopwatch, Countdown Timer, or Data Recall Mode returns to the Timekeeping Mode.

Scrolling

The B and D buttons are used on the setting screen to scroll through data on the display. In most cases, holding down these buttons during a scroll operation scrolls through the data at high speed.
Sensor Malfunction Indicator
Subjecting the watch to strong impact can cause its sensor to malfunction or improper contact of internal circuitry. When this happens, Err (error) will appear on the display and sensor operations will be disabled.
Digital Compass Measurement Barometric Pressure Measurement Altitude Measurement
If Err appears while a measurement operation is being performed in a sensor mode, restart the measurement. If Err appears on the display again, it can mean there is something wrong with the sensor. Even if battery power is at Level 1 or Level 2, the Digital Compass Mode, Barometer/Thermometer Mode, or Altimeter Mode sensor may be disabled if there is not enough voltage available to power it sufficiently. In this case, Err will appear on the display. This does not indicate malfunction, and sensor operation should resume once battery voltage returns to its normal level. If Err keeps appearing during measurement, it could mean there is a problem with the applicable sensor. Whenever you have a sensor malfunction, be sure to take the watch to your original dealer or nearest authorized CASIO distributor as soon as possible.

Power Saving

When turned on, Power Saving automatically enters a sleep state whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving. There are actually two sleep state levels: display sleep and function sleep. Elapsed Time in Dark 60 to 70 minutes (Display Sleep) 6 or 7 days (Function Sleep) Display Blank, with PS flashing Blank, with PS not flashing Operation Display is off, but all functions are enabled. All functions are disabled, but timekeeping is maintained.
Digital Compass Precautions
This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that north indicated by this watch is magnetic north, which is somewhat different from true polar north. The magnetic north pole is located in northern Canada, while the magnetic south pole is in southern Australia. Note that the difference between magnetic north and true north as measured with all magnetic compasses tends to be greater as one gets closer to either of the magnetic poles. You should also remember that some maps indicate true north (instead of magnetic north), and so you should make allowances when using such maps with this watch. Location Taking a direction reading when you are near a source of strong magnetism can cause large errors in readings. Because of this, you should avoid taking direction readings while in the vicinity of the following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal (metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal computers, washing machines, freezers, etc.) Accurate direction readings are impossible while in a train, boat, air plane, etc. Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is because the metal framework of such structures picks up magnetism from appliances, etc. Storage The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of this, you should be sure to store the watch away from magnets or any other sources of strong magnetism, including: permanent magnets (magnetic necklaces, etc.) and household appliances (TVs, personal computers, washing machines, freezers, etc.) Whenever you suspect that the watch may have become magnetized, perform one of the calibration procedures under Calibrating the Bearing Sensor.

Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state. The watch will not enter the sleep state while the digital time is between 6:00 AM and 9:59 PM. If the watch is already in the sleep state when the digital time reaches 6:00 AM, however, it will remain in the sleep state. The watch will not enter the sleep state while it is in the Countdown Timer or Stopwatch Mode.
To recover from the sleep state

Backlight Precautions

The electro-luminescent panel that provides illumination loses power after very long use. The illumination provided by the backlight may be hard to see when viewed under direct sunlight. The backlight automatically turns off whenever an alarm sounds. The watch may emit an audible sound whenever the display is illuminated. This is due to vibration of the EL panel used for illumination, and does not indicate malfunction. Frequent use of the backlight runs down the battery.
Auto light switch precautions
Wearing the watch on the inside of your wrist, movement of your arm, or vibration of your arm can cause frequent activation of the auto light switch and illumination of the display. To avoid running down the battery, turn off the auto light switch whenever engaging in activities that might cause frequent illumination of the display. Note that wearing the watch under your sleeve while the auto light switch is turned on can cause frequent illumination of the display and can run down the battery. The backlight may not light if the face of the watch is more than 15 degrees above or below More than 15 degrees parallel. Make sure that the back of your hand too high is parallel to the ground. The backlight turns off after the preset illumination duration (see To specify the illumination duration), even if you keep the watch pointed towards your face. Static electricity or magnetic force can interfere with proper operation of the auto light switch. If the backlight does not light, try moving the watch back to the starting position (parallel with the ground) and then tilt it back towards your face again. If this does not work, drop your arm all the way down so it hangs at your side, and then bring it back up again. Under certain conditions, the backlight may not light until about one second after you turn the face of the watch towards you. This does not necessarily indicate malfunction of the auto light switch. You may notice a very faint clicking sound coming from the watch when it is shaken back and forth. This sound is caused by mechanical operation of the auto light switch, and does not indicate a problem with the watch.
