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.
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.
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.

Note
• The auto light switch is always disabled, regardless of its on/off setting, when any
one of the following conditions exists.

• The electro-luminescent panel that provides illumination loses power after very long
use.
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
Auto light switch precautions
• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of
your arm can cause frequent activation of the auto light switch and illumination of
the display. To avoid running down the battery, turn off the auto light switch
whenever engaging in activities that might cause frequent illumination of the
display.
• Note that wearing the watch under your sleeve while the auto light switch is turned
on can cause frequent illumination of the display and can run down the battery.
