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.
Parallel to ground
More than 15 degrees
too high
• 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 D for one or two seconds to turn the auto light
switch function on and off.

ON
• 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 B 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 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.
