While the auto light switch is turned on, the backlight automatically lights for about two  
seconds whenever you position your wrist as described below. Avoid wearing the watch  
on the inside of your wrist. Doing so causes the auto light switch to operate when it is not  
needed, which shortens battery life.

BACKLIGHT FUNCTION  
A backlight that uses an EL (electro-luminescent) panel  
Auto light switch on indicator  
causes the entire display to glow for easy reading in the  
dark. An auto light switch causes the EL backlight to turn on  
when the watch is angled toward your face for reading. An  
EL alarm feature can be turned on so the backlight flashes  
whenever an alarm or hourly time signal sounds.  
The auto light switch on indicator is shown on the display  
in all modes while the auto light switch is on.  
Static electricity or magnetic force can interfere with proper operation of the auto light  
switch. If the auto light switch 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.

Note  
Warning!  
FLASH indicator  
The backlight of the watch employs an electro-luminescent  
(EL) light, which loses illuminating power after very long  
use.  
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 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 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.  
The illumination provided by the backlight may be hard to see when viewed under  
direct sunlight.  
The watch will emit an audible sound whenever the display is illuminated. This is caused  
by a transformer that vibrates when the EL panel lights up. It does not indicate  
malfunction of the watch.  
The backlight automatically turns off whenever an alarm sounds.  
To manually turn on the backlight  
Pressing L in the Timekeeping, Stopwatch or Alarm Mode causes the backlight to turn  
on for about two seconds. Pressing C in the Beat Counter Mode also causes the backlight  
to turn on for a fixed amount of time.  
The backlight normally stays on for about two seconds and then turns off automatically.  
When the ELalarm is turned on, however, the backlight stays on for about five seconds  
instead of two seconds.  
To turn the auto light switch on and off  
In the Timekeeping Mode, hold down C for one second to turn the auto light switch on  
(
displayed) and off (  
not displayed).  
In order to protect against running down the battery, the auto light switch is automatically  
turned off approximately three hours after you turn it on. Repeat the above procedure  
to turn the auto light switch back on if you want.  
The above operations turn on the backlight, regardless of the current auto light switch  
and EL alarm settings.
