Notes

• The backlight of the watch employs an electroluminescent (EL) light, which loses illuminating power after very long use.

• Frequent use of the backlight shortens the battery life.

• The illumination provided by the backlight may be hard to see when viewed

under direct sunlight.

• The watch will emit an audible sound whenever the display is illuminated. It does not indicate malfunction of the watch.

• The backlight automatically turns off whenever an alarm sounds.

To manually turn on the backlight

In any mode (except for the Recall Mode), press B to illuminate the display for about two seconds.

To switch the auto light switch on and off

In the Timekeeping Mode, hold down D for one or two seconds to turn the auto light switch on and off.

(EL) backlight that helps you easily read the face, even in total darkness. Its auto light switch automatically lights the watch face whenever you turn your wrist towards your

face.

Auto light switch on indicator

• The auto light switch on indicator is shown on the display in all modes while the auto light switch is on.

• In order to protect against running down the battery, the auto light switch is automatically turned off approximately six hours after you turn it on. Repeat the above procedure to turn the auto light switch back on if you want.

• Pressing B in any mode (except for the Recall Mode) illuminates the display for about two seconds, regardless of the auto light switch on/off setting.

About the auto light switch

While the auto light switch is turned on, the backlight automatically lights for about two seconds in any mode whenever you position your wrist as described below.

Important!

Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light switch to operate when it is not needed, which shortens battery life.

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 illuminate.

Parallel to ground

• The backlight may not illuminate if the face of the watch is more than 15 degrees off parallel as shown below. 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 illuminate, 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 or less after turn the face of the watch towards you. This does not necessarily indicate malfunction of the backlight.

Warning!

• Never try to read your watch when mountain climbing or hiking in areas that are dark or in areas with poor footing. Doing so is dangerous and can result in serious personal injury.

• Never try to read your watch when running where there is the danger of accidents, especially in locations where there might be vehicular or pedestrian traffic. Doing so is dangerous and can result in serious personal injury.

• Never try to read your watch when riding on a bicycle or when operating a motorcycle or any other motor vehicle. Doing so is dangerous and can result in a traffic accident and serious personal injury.

• 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.

DIGITAL COMPASS FUNCTIONS

This watch features a built-in bearing sensor that indicates any one of 16 directions. Up to five sets of direction readings can be stored into memory. Each set of data includes the direction, along with the date and time of the measurement. Direction readings can be performed in the Digital Compass Mode.

To enter and exit the Digital Compass Mode

1. In any mode (except for the Alarm Mode), press E to enter the Digital Compass Mode.

• At this time, the watch immediately starts a Digital Compass operation.

After about one second, the direction that the 12 o’clock position of the watch is pointing appears on the display.

• If you do not perform any button operation for a few minutes, the watch

automatically returns to the mode you were in before entering the Digital Compass Mode.

2. Press C to return to the mode you were in before entering the Digital Compass Mode.

• Note that when you enter the Digital Compass Mode from the Altimeter

Mode, the Altimeter Mode measurement (see “About altitude measurements”) continues to be performed internally.

Digital Compass Precautions

This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that the northern direction 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

• Using the Digital Compass when you are near a source of strong magnetism can cause large errors in readings. Because of this, you should avoid using the Digital Compass 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 measurements are impossible while in a train, boat, air plane, etc.

• Accurate measurements 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 compass 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 Digital Compass”.

Calibrating the Digital Compass

Whenever you suspect that the readings produced by the Digital Compass are wrong, you should calibrate it. You can use either one of two calibration procedures: You should use bidirectional calibration when you want to calibrate the Digital Compass to operate 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.

• If you do not perform any button operation for two or three minutes while either calibration procedure is in progress (while the magnetic north indicator is flashing at the 12 or 6 o’clock position), the watch automatically returns to the Digital Compass Mode.

northerly calibration.

• The more correctly you perform bidirectional calibration, the better the accuracy of your Digital Compass readouts. You should perform bidirectional calibration whenever you change environments where you use the Digital Compass, and whenever you feel that the Digital Compass is producing incorrect readings.

screen), hold down A until the upper display changes to show “–1–”.

• At this time, the magnetic north indicator flashes at the 12 o’clock position to indicate that the watch is ready to calibrate the first direction.

2. Place the watch on a level surface, and

press E to calibrate the first direction.

• When the calibration procedure is complete, the message “OK” appears in the upper display. This soon changes to “–2–” and the magnetic north indicator flashes at the 6 o’clock position to indicate that the watch is ready for the second direction.

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 readings from the Digital Compass.

• Do not move the watch during the one or two seconds (from the point you press E up to the point that “OK” appears in the upper display) that the calibration of each direction is in progress. If you do, the message “ERR” appears in the upper display. When this happens, restart the bidirectional calibration procedure from the beginning.

• The appearance of “ERR” during bidirectional calibration can also be caused by local interference. If you suspect that this is the case, move to another location and try the procedure again.

• You should perform bidirectional calibration in an environment that is the same as that where you plan to be using the Digital Compass. If you plan to use it in an open field, for example, calibrate in an open field.

screen), hold down A until the upper display changes to show “–1–”.

2. Press C to start the northerly calibration procedure.

• At this time, the indicator “N” appears in the

upper display.

3. Place the watch on a level surface, and position it so that its 12 o’clock position points north (as measured with another compass).

4. Press E to start the calibration operation.

CHANGING THE MEASUREMENT UNITS

You can change the measured values displayed by the watch between the following units.

Altitude: meters (m) ↔ feet (ft) Temperatures: Celsius (°C) ↔ Fahrenheit (°F) Barometric Pressure:

hecto-pascals/millibars (hPa/mb) ↔ inchesHg (inHg)

Some countries call to this unit as hecto-pascal (hPa), while other countries call it millibars (mb). It really makes no difference, because 1 hPa = 1 mb. In this manual, we will refer to hPa/mb or hPa (mb).

Important!

• Certain measurement functions are automatically terminated when you change the measurement units. Be sure that you perform this operation before starting actual measurements.

• Changing the altitude unit of measurement automatically switches off the altitude alarm, and sets the alarm’s value to zero.

• Changing the barometric pressure unit of measurement automatically restarts the barometric pressure graph from a new value.

• Changing any of the units of measurement immediately starts to display newly measured data in the unit you specify. It also affects the unit of measurement for any data already stored in memory.
