Auto light switch precautions
•
Illumination may not turn on if the face of the watch is more than
15 degrees above or below parallel. Make sure that the back of
your hand is parallel to the ground.
•
Leaving auto light enabled can run down the watch's battery due
to frequent display illumination.
•
Static electricity or magnetic force can interfere with proper
operation of the auto light switch. If illumination does not turn on,
try moving the watch back to the starting position (parallel with
the ground) and then tilt it back towards your face 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.
•
You may notice a very faint clicking sound coming from the watch when it is
shaken back and forth. This sound is caused by mechanical operation of the auto
light switch, and does not indicate a problem with the watch.
•
To protect against running down the battery, auto light switch operation
automatically disables approximately six hours after you enable it.

Illumination Precautions
•
The LED 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.

personal injury.

About the Auto Light Switch
Enabling 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.
