BACKLIGHT
This watch features an electroluminescent (EL)
backlight that helps you easily read the face, even
in total darkness. Its Auto Backlight function
automatically lights the watch face whenever you
turn your wrist towards your face.
Notes
The backlight of the watch employs an
electroluminescent (EL) light, which loses
illuminating power after very long use.
TIME TEL SCH VIT ALM STW
P
Frequent use of the backlight shortens the battery life.
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 transistor 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
In any mode, press
to illuminate the display for about one second.
To switch the Auto Backlight function on and off
In the Timekeeping Mode, hold down
for one or two seconds to turn the
auto backlight function on and off.

The auto backlight indicator is shown on the display in all modes while the
auto backlight function is on.
In order to protect against running down the battery, the auto backlight
function is automatically turned off approximately two hours after you turn it
on. Repeat the above procedure to turn the auto backlight function back on
if you want.
Pressing
in any mode illuminates the display for about one second,
regardless of the auto backlight function on/off setting.
About the Auto Backlight function
While the Auto Backlight function is turned on, the backlight automatically
lights for about one second in any mode whenever you position your wrist as
described below.
Important!
Avoid wearing the watch on the inside of your wrist. Doing so causes the Auto
Backlight to operate when it is not needed, which shortens battery life.

degrees off parallel as shown below. Make sure that the back of your hand
is parallel to the ground.

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.
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 backlight
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 backlight can create a distraction, which can
result in a traffic accident and serious personal injury.
