About the Backlight

About the Auto Light Switch Function

When the auto light switch 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 light switch 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.

E-11

To switch the auto light switch function on and off

In the Timekeeping Mode (except when making any settings), hold down

C for two seconds to turn the auto light switch function on and off.

Auto light switch indicator

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

E-12

• Pressing C in the Timekeeping Mode (except when making any settings) illuminates the display, regardless of the auto light switch’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 backlight 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 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.

E-14

Stopwatch Mode

The Stopwatch Mode has a capacity of 9 hours, 59 minutes, 59 seconds. You can also record lap times and split times, which are recorded in memory for later recall in the Recall Mode.

After the first hour

Hold down

C.

ON OFF

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

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

E-13

• 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 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 light switch can create a distraction, which can result in a traffic accident and serious personal injury.

About Laps and Splits

Lap Time

A lap time is the amount of time it takes for you to get from one point to another during a race. When running on a track, for example, you can time how long it takes you to complete each lap.

Split Time

A split time is the time from the start of a race until the point that the split is measured. For example, you could measure split times to determine how long it takes for you to get from the starting line to the 5-kilometer mark, the 10kilometer mark, etc.
