Data and Setting Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during
a scroll operation scrolls through the data at high speed.
Initial Screens
When you enter the Timekeeping, World Time, or Data Bank Mode, the data
you were viewing when you last exited the mode appears first.
World Time
•The current time in all World Time Mode cities is calculated in accordance
with the Greenwich Mean Time (GMT) differential for each city, based on the
current Home City time setting in the Timekeeping Mode.
•The GMT differential is the time difference between the time zone where the
city is located and Greenwich Mean Time. Note that the GMT differentials of
this watch is always based on standard time.
•GMT differential is calculated by this watch based on Universal Time
Coordinated (UTC) data.
Backlight Precautions
In any mode, press B to illuminate the display for about two seconds.
•The electro-luminescent panel that provides illumination loses power after
very long use.
•The illumination provided by the backlight 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.
•The backlight automatically turns off whenever an alarm sounds.
•Frequent use of the backlight shortens the battery life.
