Turning on the Backlight manually

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

• The above operation turns on the backlight regardless of the current auto light switch setting.

About the Auto Light Switch

Turning on the auto light switch causes the backlight to turn on for about two seconds, whenever you position your wrist as described below in any mode.

• See “Backlight Precautions” for other important information about using the backlight.

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 light.

Use the Timekeeping Mode to set the current time and date, to take direction and temperature readings, and to calibrate the temperature sensor.

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 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.

• The watch automatically returns to the current time and date screen if

you do not perform any operation for about 60 minutes.

Notes

• T o take a temperature reading only, simply press C in the Timekeeping

Mode. This also performs a direction reading, but the pointers and direction value will not be accurate if the watch is not oriented correctly.

• The direction value shows the direction that the 12 o’clock position of the

watch is pointing as an angle value. See “Direction Values” for details.

• After you take a direction and temperature reading in the Timekeeping

Mode, temperature readings continue to be performed every two minutes.

• See “Temperature and Direction Reading Precautions” and “Digital

Compass Precautions” for other important information about taking direction and temperature readings.

1. In the Timekeeping Mode, 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).

2. Press C to start a reading operation.

• After about one second, the current

applicable directions.

• After you are finished taking direction

readings, press D to return to the current time and date screen.

Calibrating the Temperature Reading

The temperature sensor of this watch is calibrated at the factory before shipment and further adjustment is normally not required. If you notice significant error in the temperature readings produced by this watch, you can adjust it to correct the error.

Important!

Incorrectly calibrating the temperature reading of this watch can result in incorrect readings. Carefully read the following before doing anything.

• Compare the readings produced by the watch with those of another reliable, accurate thermometer.

• If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the temperature of the watch time to stabilize.

To calibrate the temperature reading

• T o return the temperature reading to its initial factory default calibration, press B and C at the same time.

• You can change the displayed temperature value by ±9.9°C. The overall temperature reading adjustment range is –10.0°C to 60.0°C.

4. After calibrating the temperature, press A to return to the measurement result screen.

• To return to the current time and date screen, press D.

1. In the Timekeeping Mode, press C to
