Alarms
You can set five independent Daily Alarms. When an
alarm is turned on, the alarm tone sounds when the alarm
time is reached. One of the alarms is a snooze alarm,
while the other four are one-time alarms.

watch to beep twice every hour on the hour.
There are six screens in the Alarm Mode. Four are for
one-time alarms (indicated by numbers from

Auto Return Feature
If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically exits the setting screen.
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 World Time or Alarm Mode, the data you were viewing when you
last exited the mode appears first.
Timekeeping
Resetting the seconds to
00
while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to
00
without changing the minutes.
With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
The year can be set in the range of 2000 to 2039.
The watchs 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 watchs batteries replaced.
World Time
The World Time Mode times are calculated from the current Home City time setting
in the Timekeeping Mode, using the Greenwich Mean Time (GMT) differentials
associated with each city code.
The GMT differential is a value that indicates the time difference between Greenwich
Mean Time and the time zone where a city is located.
GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC) data.
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 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.
