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.

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.
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 even if the face is
covered only partially.
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. Make 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.
