The backlight uses an EL (electro-luminescent)
panel that cause the entire display to glow for
easy reading in the dark. The watch's auto light
switch automatically turns on the backlight when
you angle the watch towards your face.
· The auto light switch must be turned on
(indicated by the auto light switch on indicator)
for it to operate.
Note
· The electro-luminescent panel loses
illuminating power after very long use.
· 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 vibration of the EL panel when it is lit. It does not indicate
malfunction of the watch.
· The backlight automatically turns off whenever an alarm sounds.
To manually turn on the backlight
Depending on the mode, pressing L or D turns on the backlight for about two
seconds. See the sections that cover each mode for information on whether
you should press L or D .
· The backlight remains lit for about two seconds from the point you press the
button, even if it is already lit when you press the button. If you keep the
button depressed for five seconds or more, the backlight automatically turns
off.
· The above operation turns on the backlight regardless of the current auto
light switch setting.
About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on whenever you
position your wrist as described below. Note that the auto light switch of this
watch will operate only when available light is below a certain level. It does not
turn on the backlight under bright light.
· 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.

increase the selection or B to decrease it. The 12/24-hour setting is selected
(flashing), press D to switch between the 12-hour (
12H) and 24-hour
(
24H) formats.
· Holding down either button changes the current selection at high speed.
· With the 12-hour format, the P (PM) indicator appears to the left of the hour
digits for times in the range of noon to 11:59 pm and the A (AM) indicator
appears to the left of the hour digits for times in the range of midnight to 11:59
am.
· The 24-hour format is indicated by 24 on the display. Times are shown in the
range of 00:00 to 23:59.
5. After you set the time and date, press A to return to the Timekeeping Mode.
· The day of the week is automatically set in accordance with the date.
· The date can be set within the range of January 1, 1995 to December 31,
2039.

the flashing stops and the watch goes back to the Timekeeping Mode
automatically.

Moving the watch to a position that is parallel to the ground and then tilting it
towards you more than 40 degrees causes the backlight to light.
· The backlight turns off in about two seconds, even if you keep the watch
pointed towards your face.
· The backlight may not light if the face of the watch is more than 15 degrees
off the parallel as shown below. Make sure that the back of your hand is
parallel to the ground.
Parallel to
ground
More
than
40
°
More than 15 degrees
too high
More than 15 degrees

Parallel to ground
· Static electricity or magnetic force can interfere with proper operation of the
auto light switch. If the backlight does not light, 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 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.
To turn the auto light switch on and off
In the Timekeeping Mode, hold down D for one second to turn the auto light
switch on ( AUTO
displayed) and off ( AUTO
not displayed).
· Frequent use of the auto light switch greatly reduces the charge of the storage
battery. If you use the auto light switch often, be sure to leave the watch
where it is exposed to sunlight during the day time so it can recharge the
storage battery. 10 minutes exposure to sunlight provides enough of a charge
for about 10 to 20 auto light switch operations.
· The AUTO
indicator is on the display in all modes while the auto light switch
is turned on.
