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.

• 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.

too high too low

• 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.

To switch the auto light switch function on and off

In the Timekeeping Mode, hold down

B for one or two seconds to turn the auto light

switch function on and off.

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 three hours after you turn it on. Repeat the

above procedure to turn the auto light switch function back on if you want.

• Pressing

L while in the Timekeeping Mode 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 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 acci-

dents, 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 dis-

traction, which can result in a traffic accident and serious personal injury.
