E-53
Illumination
This watch has an EL (electro-luminescent) panel that causes the entire display to
glow for easy reading in the dark. In any mode (except when a setting screen is on
the display), press
B
to illuminate the display for about three seconds.
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 turns off automatically whenever an alarm sounds.
Frequent use of illumination runs down the battery.
E-52
The UTC offset 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.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.
With the 12-hour format, the PM indicator (
P
) 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.
E-51
The watch’s Home City code setting will change automatically to
TYO
(Tokyo)
whenever the battery goes dead or is replaced.
TYO
(Tokyo) causes the watch to
receive the time calibration signals of Japan. If you are using the watch in North
America or Europe, you will need to change the Home City code setting to match
your location after having the watch’s battery replaced.
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.
The day of the week is displayed automatically in accordance with the date (year,
month, and day) settings.
The year can be set in the range of 2000 to 2099.
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 battery replaced.
The times for the Timekeeping Mode and all the city codes of the World Time Mode
are calculated in accordance with each city’s UTC offset.
E-50
Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to
time data only.
Normally, the signal reception date shown by the Last Signal screen is the
date data included in the received time calibration signal. When only time data
is received, however, the Last Signal screen shows the date as kept in the
Timekeeping Mode at the time of signal reception.
If you are in an area where proper time calibration signal reception is impossible,
the watch keeps time with the precision noted in “Specifications”.
If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your current city code (page E-10), DST
(summer time) (page E-45), and auto receive settings (page E-25). The following are the
initial factory defaults for these settings.
