The backlight uses an EL (electro-lumines- cent) panel that causes the entire display to glow for easy reading in the dark. The watch’s auto light switch automatically turns on the backlight when you angle the watch towards your face.

∙The auto light switch must be turned on (indicated by the auto light switch on indicator) for it to operate.

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.

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.

∙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.

∙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.

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

1.In the Timekeeping Mode, press C to perform a direction and temperature
