Operation Guide 3178
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 the preset illumination
duration (see “To specify the illumination duration”),
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 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.
•
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.

Based on data as of March 2008.
•
The rules governing global times (UTC offset and GMT differential) and summer
time are determined by each individual country.
* In December 2007, Venezuela changed its offset from –4 to –4.5. Note, however,
that this watch displays an offset of –4 (the old offset) for the CCS (Caracas,
Venezuela) city code.
