Illumination

An LED (light-emitting diode) illuminates the face of the
Auto light switch
watch for easy reading in the dark. The watch's auto light
on indicator
switch turns on illumination automatically 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.
See "Illumination Precautions" (page E-52) for other
important information about using illumination.
To illuminate the display manually
In any mode (except a setting mode), press B to turn on
the illumination for about one second.
The above operation turns on illumination regardless of
the current auto light switch setting.

Power Supply

This watch is equipped with a solar cell and a special rechargeable battery (secondary
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 even only
partially covered.

Alarm Operation
The alarm tone sounds at the preset time for 10 seconds, regardless of the mode the
watch is in. In the case of the snooze alarm, the alarm operation is performed a total
of seven times, every five minutes, or until you turn the alarm off (page E-32).
Alarm and Hourly Time Signal operations are performed in accordance with the
current time in your Home City, as kept in the Timekeeping Mode.
To stop the alarm tone after it starts to sound, press any button.
Performing any one of the following operations during a 5-minute interval between
snooze alarms cancels the current snooze alarm operation.

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 LED Light", so the auto light switch operates
only when available light is below a certain level. It does not illuminate the display
under bright light.
The auto light switch is always disabled, regardless of its on/off setting, while an
alarm is sounding.
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 B 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.
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 special 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 special rechargeable battery to charge fully, contact your dealer
or CASIO distributor about having it replaced.
Never try to remove or replace the watch's special 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 (CHG)
(page E-40) and when you have the battery replaced.
Turn on the watch's Power Saving function (page E-48) 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.
