dark.
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 automatically turns off whenever an alarm
sounds.
• Frequent use of illumination runs down the battery.

off.
Auto Return Features
• If you leave the watch in the Alarm Mode for two or three minutes without performing
any operation, it changes to the Timekeeping Mode automatically.

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 scrolls at high
speed.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when you
last exited the mode appears first.
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 “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.
