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 any mode except for the Stopwatch Mode and Altimeter 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 saves anything you have input up to that point and exits the setting screen.
More than 15 degrees too high
� The backlight may not light if the face of the watch is more than 15 degrees above or below parallel. Make sure that the back of your hand is parallel to the ground. � The backlight turns off in about two seconds, even if you keep the watch pointed towards your face.
Direct Timekeeping Mode Access
Holding down D while in the Data Recall Mode, Alarm Mode, or Stopwatch Mode goes directly to the Timekeeping Mode. � Note that the above does not work while a setting screen (one with flashing digits, etc.) is on the display. The E and B buttons are used in various modes and setting screens 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.
Scrolling
� 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 toward you 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 backlight. � 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.
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. � Movement of the analog hands during digital compass operation in an area where terrestrial magnetism is weak can cause the pointer position and angle value to be slightly off. 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�.
Power Saving Function
When turned on, the Power Saving function automatically puts the watch into a sleep state whenever it is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by the Power Saving function. Elapsed Time in Dark 60 to 70 minutes Display Blank, with SLEEP flashing Blank, with SLEEP not flashing Operation Display is off, but all functions are enabled and analog hand operation is maintained. All functions are disabled, but timekeeping (digital and analog) is maintained.
6 or 7 days
� 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 Digital Compass Mode, Barometer/Thermometer Mode, Altimeter Mode, or Stopwatch Mode. When the watch is left in any mode besides the Stopwatch Mode, the watch will return to the Timekeeping Mode automatically after a specific amount of time. Then if left in the dark for the elapsed time indicated in the table above, the watch will enter the sleep state.
To recover from the sleep state
Perform any one of the following operations. � Move the watch to a well-lit area. It can take up to two seconds for the display to turn on. � Press any button. � Angle the watch towards your face for reading.
To turn Power Saving on and off
1. In the Timekeeping Mode, hold down A until the seconds start to flash, which indicates the setting screen. 2. Press D eight times until the Power Saving on/off screen appears. 3. Press E to toggle Power Saving on (ON) and off (OFF). 4. Press A to exit the setting screen. � The Power Saving on indicator (SAVE) is on the display in all modes while the Power Saving is turned on.
Calibrating the Bearing Sensor
Whenever you suspect that direction readings produced by the watch are wrong, you should calibrate it. You can use either one of two calibration procedures: bidirectional calibration or northerly calibration. Use bidirectional calibration when you want to take readings within an area exposed to magnetic force. This type of calibration should be used if the watch becomes magnetized for any reason. With northerly calibration, you �teach� the watch which way is north (which you have to determine with another compass or some other means). You could use this calibration procedure, for example, to set the watch to indicate true north instead of magnetic north. Important! � If you want to perform both bidirectional and northerly calibration, be sure to perform bidirectional calibration first, and then perform northerly calibration. This is necessary because bidirectional calibration cancels any previously set northerly calibration setting. � The more correctly you perform bidirectional calibration, the better the accuracy of the bearing sensor readouts. You should perform bidirectional calibration whenever you change environments where you use the bearing sensor, and whenever you feel that the bearing sensor is producing incorrect readings. Precautions about bidirectional calibration � You can use any two opposing directions for bidirectional calibration. You must, however, make sure that they are 180 degrees opposite each other. Remember that if you perform the procedure incorrectly, you will get wrong bearing sensor readings. � Make sure that you do not move the watch while calibration of either direction is in progress. � You should perform bidirectional calibration in an environment that is the same as that where you plan to be taking direction readings. If you plan to take direction readings in an open field, for example, calibrate in an open field.

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.
