To illuminate the display

• The above operation turns on illumination regardless of the current auto light switch
setting.
About the Auto Light Switch
While the auto light switch is enabled, illumination turns on whenever you position
your wrist as described below in any mode.
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.
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.
This 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 turns on illumination
automatically when you angle the watch for reading
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 more important
information.

light switch on (auto light switch indicator displayed) or off (auto light switch indicator
not displayed).
• The auto light switch indicator is on the display in all modes while the auto light
switch is turned on.
• In order to protect against running down the battery, the auto light switch turns off
automatically approximately six hours after you turn it on.

back towards you again. If this does not work, drop your
arm all the way down so it hangs at your side, and then
bring it back up again.
