2. OPERATION CHART : QW-1845
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.
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 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 for one or two seconds to turn the auto light
switch function on and off.
The Telememo Mode lets you store up to 30 pairs
of name and telephone number data. The name
can be up to 8 characters long and the number up
to 12 digits. Data is automatically sorted into
alphabetical order based on the name data. You
can recall data by scrolling through it on the display.

The auto light switch indicator is shown on the display in all modes while the auto light

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 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 backligfht shortens the battery life.
The watch emits an audible sound whenever the display is illuminated. This is
because 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 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
