Operation Guide 3420
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, disable 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" (page E-30)), 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.

* As of December 2012, the offi cial UTC offset for Caracas, Venezuela (CCS) has
been changed from –4 to –4.5, but this watch still uses an offset of –4 (the old
offset) for CCS.
** As of December 2012, the offi cial UTC offset for Moscow, Russia (MOW) has
been changed from +3 to +4, but this watch still uses an offset of +3 (the old
offset) for MOW. Because of this, you should leave the summer time setting
turned on (which advances the time by one hour) for the MOW time.
This table shows the city codes of this watch.
The rules governing global times (UTC offset and GMT differential) and summer
time are determined by each individual country.
