measurements that require professional or industrial precision. Values produced
by this watch should be considered as reasonable representations only.
•The Moon phase indicator and tide graph data that appear on the display of this
watch are not intended for navigation purposes. Always use proper instruments
and resources to obtain data for navigation purposes.
•This watch is not an instrument for calculating low tide and high tide times. The

Keep the watch exposed to bright light
The electricity generated by the solar cell of the watch is
stored by a rechargeable battery. Leaving or using the
watch where it is not exposed to light causes the battery
to run down. Make sure the watch is exposed to light as
much as possible.
•When you are not wearing the watch on your wrist,
position the face so it is pointed at a source of bright
light.
•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.

•The watch continues to operate, even when it is not exposed to light. Leaving the
watch in the dark can cause the battery to run down, which will result in some watch
functions to be disabled. If the battery goes dead, you will have to re-configure watch
settings after recharging. To ensure normal watch operation, be sure to keep it
exposed to light as much as possible.
E-3
•The actual level at which some functions are disabled depends on the watch model.
•Frequent display illumination can run down the battery quickly and require charging.
•Be sure to read “Power Supply” (page E-41) for important information you
need to know when exposing the watch to bright light.
If the display of the watch is blank...
If the display of the watch is blank, it means that the watch’s Power Saving function
has turned off the display to conserve power.
•See “Power Saving Function” (page E-59) for more information.

Countdown Timer
Dual timers can be set with two different starting times.
The watch can be configured so the two timers alternate,
so when one reaches the end of its countdown, the other
timer starts. You can specify a “number of repeats” value,
which controls how many times the two-timer countdown
operation is performed (1 = once, 2 = twice, etc.). The
starting time of each timer can be set in five-second steps
up to 99 minutes, 55 seconds.
You can specify up to 10 repeats. The watch emits a short
beep whenever either of the timers reaches the end of its
countdown during an ongoing timer operation. The watch
emits a 5-second beep when the end of the final timer
operation (specified by the number of repeats) is reached.
Countdown End Beeper
The countdown end beeper lets you know when the countdown reaches zero. The
beeper stops after about 5 seconds or when you press any button.

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.
Parallel to
ground More than 40°

•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.

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
E-42
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 (pages
E-43 and E-44) and when you have the battery replaced.
•Turn on the watch’s Power Saving function (page E-59) 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.
•
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 the recover indicator to appear
on the display.
After some time, battery power will recover and the
recover indicator will disappear, indicating that the above
functions are enabled again.
•If the recover indicator appears frequently, it probably
means that remaining battery power is low. Leave the
watch in bright light to allow it to charge.

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
•Too close to an incandescent lamp
•Under direct sunlight
