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.

GENERAL GUIDE

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 More than 15 degrees More than 15 degrees

• 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 towards 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 turning the face of the watch towards you. This does not necessarily indicate malfunction of the backlight.

STOPWATCH MODE

The Stopwatch Mode lets you measure elapsed time, lap times, and split times. Time is measured with 1/100 of a second accuracy. You can also store up to 10 lap and split times in memory.

Lap/split number

Upper display

• The lap time appears in the upper part of the display. You can use this function to time how long it takes to complete a specific portion (such as a single lap) of a race.

• The split time appears in the lower part of the display. You can use this function to time how long it takes to get from the start to a specific point in a race.

• 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 three hours after you turn it on. Repeat the above procedure to turn the auto light switch function back on if you want.

• Pressing 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 be-

cause 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.

• 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 the memory function

Whenever you perform a lap/split time operation, the measured times are automatically stored into memory along with the lap/split number. You can store up to 10 lap/ split times in memory. If you perform more than 10 lap/split time operations, the memory will contain the times for the first 9 laps/splits (as lap/split numbers 1 through 9), and the final lap and split time (as lap/split 10).

Data in the lap/split memory is cleared whenever you start a new stopwatch timing operation. For details on recalling data in the lap/split memory, see “DATA RECALL MODE”.
