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.
Parallel to ground
More than
40
°
• 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.
• 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 acci-
dents, 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 vehi-
cle. Sudden and unintended operation of the auto light switch can create a dis-
traction, 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 D D D 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.
MOON DATA MODE
Be sure to set the current time and your current location before trying to use the
Moon Data Mode.
The Moon Data Mode display shows the current moon age, as well as moon up and
moon down times. Moon age is indicated both by a value and one of the following
graphics.
Parallel to ground More than 15 degrees
too high More than 15 degrees
too low
• The moon up time indicates when the moon will
reach its highest point relative to your current lo-
cation (upper transit), while the moon down time
indicates when it will reach its lowest point (lower
transit). Note that moon up and moon down times
are accurate up to
± 30 minutes.
To display the moon up and moon down time for a specific date
• The moon data for your home time point appears first
when you enter the Moon Data Mode.
• Press D D D D D (forward) or B B B B B (back) within about two
seconds after entering the Moon Data Mode to scroll to
another point. Holding down either button scrolls at high
speed. It takes about 40* seconds before moon data
appears after you display the name of a point.
• If you do not perform any button operation, about two
seconds after you enter the Moon Data Mode the
display changes automatically to show the moon data
for today’s date. Pressing
D D D D D advances to the next date,
while B B B B B goes back to the previous date. Holding down
either button scrolls the date at high speed. It takes about
40* seconds before moon data appears after you dis-
play a date.
* While the countdown alarm is operating, it takes about
three and a half minutes to calculate.
• Note that once you enter the moon data display, you
cannot change to another point. To change to another
point, press
A A A A A twice to return to the point name
display, make the changes you want, and then re-enter
the moon data display.
• Moon data is displayed in 5-minute units.
• For days around the full moon (moon age 15) or new
moon (moon age 29.5), there are days where there is
no moon up or moon down. In such cases, the
xx : xx
is shown for the moon up or moon down time.

Mode.
2. Use D D D D D (forward) and B B B B B (back) to scroll the time in 1-
hour increments. Holding down either button changes
the time at high speed.
• Note that once you enter the Tide Graph Mode, you
cannot change to another point or date. To change to
another point or date, press
A A A A A to return to the Moon
Data Mode, make the changes you want, and then
re-enter the Tide Graph Mode.

to another point. Holding down either button scrolls at
high speed. It takes about 40* seconds before sunrise/
sunset data appears after you display the name of a point.
• If you do not perform any button operation, about two
seconds after you enter the Sunrise/Sunset Mode the
display changes automatically to show the sunrise/
sunset data for today’s date. Pressing

BACKLIGHT
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
• In the Timekeeping Mode, press D D D D D to illuminate the display for about two seconds.
• 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 posi-
tion 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.
