World Time
•
The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
•
All World Time Mode times are calculated from the current Home City time in the
Timekeeping Mode using UTC time differential values.
•
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 “Universal Time Coordinated”, 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 turns off automatically whenever an alarm sounds.
•
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 in about one 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 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.
