ABOUT THE BACKLIGHT

About the Auto Backlight Function

When the auto backlight function is turned on, the backlight automatically turns on for two seconds under the conditions described below. Avoid wearing the watch on the inside of your wrist. Doing so causes the auto backlight to operate when not needed, which shortens battery life.

Moving the watch to a position that is parallel to the ground and then tilting it towards you approximately 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 to the left or right. Make sure that the back of your hand is parallel to the ground.

Parallel to ground

• Static electricity or magnetic force can interfere with proper operation of the auto backlight function. If the auto 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.

To switch the auto backlight function on and off

In the Timekeeping Mode, hold down for one or two seconds to turn the auto backlight function on and off.

• The auto backlight indicator is shown on the display in all modes while the auto backlight function is on.

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

• Pressing at any time illuminates the display for about two seconds, regardless of the auto backlight's on/off setting.

Caution

• The backlight of this watch employs an electro-luminescent (EL) light, which loses its illuminating power after very long term use.

• Frequent use of the backligfht shortens the battery life.

• The watch emits an audible sound whenever the display is illuminated. This is because the EL light vibrates slightly when lit. It does not indicate malfunction of the watch.

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 on a roadside or in any other location 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 backlight function is turned off before riding on a bicycle or operating a motorcycle or any other motor vehicle. Sudden and unintended operation of the auto backlight can create a distraction, which can result in a traffic accident and serious personal injury.

THERMOMETER MODE

A built-in temperature sensor measures temperature and shows the measured value on the display. The readout from the temperature sensor can also be switched between Celsius (˚C) and Fahrenheit (˚F). The thermometer can be calibrated to correct for errors.

Important!

Temperature measurements are affected by your body temperature (while you are wearing the watch), direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe off all moisture from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual surrounding temperature.

Accurate temperature measurements cannot be achieved while you are wearing the watch. The following graph illustrated affects of body temperature on actual temperature.

About Temperature Measurement

• A temperature graph which is automatically updated every five minutes, is shown on the display in all modes (except when making settings). Measured temperature values can be viewed in the Thermometer Mode only.

Calibrating the Temperature Measurement

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

Important!

Incorrectly calibrating the temperature measurement 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 calibration 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.

•Perform the temperature calibration before procedure as quickly as possible to avoid the temperature of the watch being affected by your body temperature.

•You can also perform temperature calibration underwater, if the water temperature is stable.

You can change the measurement units displayed by the watch between the following. Stride Length: Centimeters (cm) Inches (inch) Distance: Kilometers (km)

To change the measurement units

While the stride length is flashing on the display as described under “To set your stride length,” press to toggle between metric and inch/mile measurement units.

•Note that changing the measurement units automatically clears the stride length setting. This means that if you want the Trekking Counter to calculate and display the distance you cover, you must re-input your stride length whenever you change the measurement units.

Important!

•The Trekking Counter is not intended for use as an all-day pedometer. Trekking Counter operation requires considerable battery power, so be sure to press to stop its operation after you are through using it. Next, press to return to the Timekeeping Mode.

•To protect against prematurely running down the battery, Trekking Counter operation turns off automatically and the watch emits a 2-second beep to alert you if the Trekking Counter is left on for more than 24 hours. Note that measured values up to the point that the Trekking Counter turns off are retained, so you can start the next operation from the displayed values.

To use the Trekking Counter

1.Press to start Trekking Counter operation.

•Elapsed time, number of steps, and distance covered are all shown on the display while the Trekking Counter is operating.

2.Press to temporarily stop Trekking Counter Operation.

The Trekking Counter counts how many steps you take and elapsed time while walking. After you input the length of your stride, it also automatically calculates and displays the distance you have covered.

Important!

•The Trekking Counter cannot count the number of

Steps

steps you take if the watch is on your wrist. Be sure to wear the watch on your waist as described in “USING THE BAND CLIP”.

•Note that the accuracy of data measured by the Trekking Counter can be affected when you are walking on sand or other soft ground, on a steep upgrade, or on a steep downgrade.

Important!

•If you plan on changing the measurement units, be sure do so before setting your stride length. Changing the measurement units automatically clears the stride length setting, which means you will have to re-input it.
