ABOUT THE BACKLIGHT
The EL backlight of this watch is designed to start working on December 25, 1999.
The backlight will not work until this date, even if you try to set the date setting ahead
to December 25.
All the backlight operations described in this User’s Guide can be performed after
December 25, 1999.
• Be sure to set the correct date and time after purchasing the watch.
• In the Timekeeping Mode and Alarm Mode, (except when making any settings),
press

in the Timekeeping Mode, the figures on the display disappear for about the final two

E
E
to illuminate the
display for about four seconds.
• When making timekeeping and alarm settings, press

• 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 does not
indicate malfunction of the watch.
• The illumination provided by the backlight may be hard to see when viewed under
direct sunlight.
• The backlight automatically turns off whenever an alarm sounds.
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.
• 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.

More than 15 degrees
too high
More than 15 degrees
too low
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.

• 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 light switch function on and off
In the Timekeeping Mode, hold down
E
E
for one or two seconds to turn the auto light
switch function on and 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 two hours after you turn it on. Repeat the
above procedure to turn the auto light switch function back on if you want.
• Pressing
D
D
(Timekeeping Mode, Alarm Mode) or
E
E
(Countdown Alarm Mode,
Stopwatch Mode) illuminates the display for about four seconds, regardless of the
backlight’s on/off setting.
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 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.
