Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto Return Feature
•The watch automatically returns to the Timekeeping Mode if you do not perform any
button operation for two or three minutes in the Telememo, Alarm, or Hand Setting
Mode.
•If you leave a screen with flashing digits or a cursor on the display for two or three
minutes without performing any operation, the watch automatically exits the setting
screen.

Timekeeping Mode. This operation does not work while a setting screen is on the
display.
Scrolling
The Band Dbuttons 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 Telememo, World Time, or Alarm Mode, the data you were
viewing when you last exited the mode appears first.
World Time
•The UTC differentials associated with each city code are used to calculate World
Time Mode times, based on the time you set for any one of the World Time cities.
•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.
Backlight Precautions
The backlight uses an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark. In any mode, press Bto illuminate the display for
about one second.
•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.
