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 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 World Time orAlarm 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 watch’s 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 watch’s 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 UniversalTime 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 Bto 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.

6. PRECAUTIONS FOR REPAIR: MODULE QW-4314
6-1. AC (ALL CLEAR) AND REMOVING OF MODULE
1. Perform AC (ALL CLEAR) when inserting a new battery, or else the memories and/or counters may
give erratic displays.
Touch the AC contact and the main plate with the metallic tweezers.
The contact should be made for about two seconds.
6-2. ACCURACY CHECKING
Check the accuracy of the module with the quartz timer after switching the module to “ACCURACY
CHECKING MODE”.
The operations are shown below:
A) SWITCHING TO “ACCURACY CHECKING MODE”
While pressing the Abutton, press Cand Dbuttons at the normal time keeping mode.
Then all the segments are displayed and the LCD drive signals are changed to the static drive signal
of “32 Hz” so that you can check the accuracy with the quartz timer.
B) CANCELLATION OF THE “ACCURACY CHECKING MODE”
Press any button except for Dbutton.
Then the display is returned to its original state.
NOTE: The “ACCURACY CHECKING MODE” will
automatically return to the regular mode in 1 ~ 2
