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 Digital Compass Mode 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 four or five hours in the Short Mode, or after nine or 10 hours in the Long Mode.

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.

Power Saving Function

When turned on, the Power Saving function automatically puts the watch into a sleep state whenever it is left in an area where it is dark for a certain period. The table below shows how watch functions are affected by the Power Saving function.

Wearing watch inside the sleeve of clothing can cause it to 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 five 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

Data and Setting Scrolling

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.

Timekeeping

Resetting the seconds to 00 while the current count is in the range of 30 to 59 causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are reset to 00 without changing the minutes.

The year can be set in the range of 2000 to 2039.

The watch’s built-in full automatic calendar automatically makes allowances for different month lengths and leap years. Once you set the date, there should be no reason to change it except when battery power drops to Level 4.

12-hour/24-hour Timekeeping Formats

The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also applied in all modes.

With the 12-hour format, the P (PM) indicator appears on the display for times in the range of noon to 11:59 p.m. and no indicator appears for times in the range of midnight to 11:59 a.m.

With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without any indicator.

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 and movement or vibration of your arm can cause the auto light switch to activate and illuminate 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.

More than 15 degrees

The backlight may not light if the face of the

watch is more than 15 degrees above or below

too high

 

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.

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.

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 ferro- concrete 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”.

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 become 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.
