Backlight
The backlight uses an EL (electro-luminescent) panel that
Auto light switch on indicator
causes 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
in the dark.
The auto light switch must be turned on (indicated by
the auto light switch on indicator) for it to operate.
See "Backlight Precautions" for other important
information about using the backlight.

About the Auto Light Switch
Turning on the auto light switch causes the backlight to turn on for about one second,
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 the backlight to turn on.

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
surprise or distract others around you.
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
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 any mode, hold down L for about two seconds to toggle the auto light switch on
(auto light switch on indicator displayed) or 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.
Battery
This watch is equipped with a solar cell and a 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.
Note that charging efficiency drops
when any part of the solar cell is
blocked by clothing, etc.
