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.
• When you are wearing the watch, make sure that its auto light switch is disabled 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 traffi c accident
and serious personal injury.
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.
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, disable 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 enabled can cause
frequent illumination of the display and can run down the battery.
• 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.
• Illumination turns off after the preset illumination duration (page E-106), even if you keep
the watch pointed towards your face.
• 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.
