Operation Guide 3150

Auto light switch precautions

•

Avoid wearing the watch on the inside of your wrist. Doing so causes the
auto light switch to operate when it is not needed, which shortens battery
life. If you want to wear the watch on the inside of your wrist, turn off the
auto light switch feature.

•

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 a preset amount of
time (1.5 or 3 seconds), 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 toward
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.

More than 15 degrees
too high

•

Under certain conditions, illumination may not turn on until about one
second after you turn the face of the watch towards you. This does not
necessarily indicate malfunction of the auto light switch.

•

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.
