Operation Guide 3247
The watch’s built-in full automatic calendar makes allowances for different month •
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
World Time
All World Time Mode times are calculated from the current Home City time in the
Timekeeping Mode using UTC time differential values.
The seconds count of the World Time is synchronized with the seconds count of the •
Timekeeping Mode.
The UTC differential is a value that indicates the time difference between a •
reference point in Greenwich, England and the time zone where a city is located.
The letters “UTC” is the abbreviation for “Coordinated Universal Time”, which is the •
world-wide scientific standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s
rotation.
Illumination Precautions
The electro-luminescent panel that provides illumination loses power after very long •
use.
Illumination may be hard to see when viewed under direct sunlight. •
The watch may emit an audible sound whenever the display is illuminated. This •
is due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
Illumination will turn off automatically if an alarm starts to sound while Flash Alert is •
turned off. When Flash Alert is turned on, illumination will flash with the alarm.
Frequent use of illumination runs down the battery. •
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” (page E-33)),
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.
