Illumination
The watch has an EL (electro-luminescent) panel that
causes the entire display to glow for easy reading in the
dark. The watch’s auto light switch illuminates the display
automatically when you angle the watch towards your
face.
• The auto light switch must be turned on (indicated by
the auto light switch indicator) for it to operate.
• See “Illumination Precautions” for other important
information.
To turn on illumination manually
In any mode, press L to illuminate the display.
• You can specify 1.5 seconds or 2.5 seconds as the
illumination duration. See “To set the time and date” for
more information.
• The above operation turns on illumination regardless of
the current auto light switch setting.

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 illuminate the display under bright light.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you at more than 40 degrees causes illumination to turn on.
• Wear the watch on the outside of your wrist.

More than
40°
Warning!
• Always make sure you are in a safe place whenever you are reading 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 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 indicator displayed) and off (auto light switch indicator not displayed).
• The auto light switch indicator remains in all modes while the auto light switch is
turned on.
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 only partially
covered.
