About the Auto Light Switch
Turning on the auto light switch causes illumination to turn on, whenever you position
your wrist as described below in any mode. Note that this watch features a “Full Auto
EL Light,” so the auto light switch operates only when available light is below a certain
level. It does not turn on the backlight under bright light.
Moving the watch to a position that is parallel to the ground and then tilting it towards
you more than 40 degrees causes illumination to turn on.
•
Wear the watch on the outside of your wrist.

ground
More than 40°
Warning!
•••••
Always make sure you are in a safe place whenever you are reading the
display of the watch using the auto light switch. Be especially careful when
running or engaged in any other activity that can result in accident or injury.
Also take care that sudden illumination by the auto light switch does not
startle or distract others around you.
•••••
When you are wearing the watch, make sure that its auto light switch is
turned off before riding 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
L
for about three seconds to toggle the auto
light switch on (auto light switch on indicator
displayed) and off (auto light switch on
indicator not displayed).
•
The auto light switch on indicator is on the display in all modes while the auto light
switch is turned on.
Power Supply
This watch is equipped with a solar cell and a rechargeable battery that is charged by
the electrical power produced by the solar cell. The illustration shown below shows
how you should position the watch for charging.
Example:
Orient the watch so its face is
pointing at a light source.
•
The illustration shows how to position a
watch with a resin band.
•
Note that charging efficiency drops when
any part of the solar cell is blocked by
clothing, etc.
•
You should try to keep the watch outside of
your sleeve as much as possible. Charging
is reduced significantly if the face is
covered only partially.
Solar cell
Important!
•
Storing the watch for long periods in an area where there is no light or wearing it in
such a way that it is blocked from exposure to light can cause rechargeable battery
power to run down. Be sure that the watch is exposed to bright light whenever
possible.
•
This watch uses a rechargeable battery to store power produced by the solar cell, so
regular battery replacement is not required. However, after very long use, the
rechargeable battery may lose its ability to achieve a full charge. If you experience
problems getting the rechargeable battery to charge fully, contact your dealer or
CASIO distributor about having it replaced.
•
Never try to remove or replace the watch’s rechargeable battery yourself. Use of the
wrong type of battery can damage the watch.
•
All data stored in memory is deleted, and the current time and all other settings
return to their initial factory defaults whenever battery power drops to Level 5 and
when you have the battery replaced.
•
Turn on the watch’s Power Saving function and keep it in an area normally exposed
to bright light when storing it for long periods. This helps to keep the rechargeable
battery from going dead.

The flashing
LOW
indicator at Level 3 tells you that battery power is very low, and
that exposure to bright light for charging is required as soon as possible.
•
At Level 5, all functions are disabled and settings return to their initial factory
defaults. Once the battery reaches Level 2 after falling to Level 5, reconfigure the
current time, date, and other settings.
•
The watch’s Home City code setting will change automatically to
TYO
(Tokyo)
whenever the battery drops to Level 5. With this Home City code setting, the watch is
configured to receive the time calibration signals of Japan. If you are using the watch
in North America or Europe, or China you will need to change the Home City code
setting to match your location whenever the battery drops to Level 5.
•
Display indicators reappear as soon as the battery is charged from Level 5 to Level 2.
•
Leaving the watch exposed to direct sunlight or some other very strong light source
can cause the battery power indicator to show a reading temporarily that is higher
than the actual battery level. The correct battery level should be indicated after a few
minutes.
•
Performing illumination, or beeper operations during a
short period may cause
(recover) to appear on
the display.
After some time, battery power will recover and
(recover) will disappear, indicating that the above
functions are enabled again.
•
If
(recover) appears frequently, it probably means
that remaining battery power is low. Leave the watch in
bright light to allow it to charge.

Charging Precautions
Certain charging conditions can cause the watch to become very hot. Avoid leaving
the watch in the areas described below whenever charging its rechargeable battery.
Also note that allowing the watch to become very hot can cause its liquid crystal
display to black out. The appearance of the LCD should become normal again when
the watch returns to a lower temperature.
Warning!
Leaving the watch in bright light to charge its rechargeable battery can cause it
to become quite hot. Take care when handling the watch to avoid burn injury.
The watch can become particularly hot when exposed to the following
conditions for long periods.
•
On the dashboard of a car parked in direct sunlight
