• Normally , the signal reception date shown by the Last Signal screen is the date data
included in the received time calibr ation signal. When only time data is received,
howe ver , the Last Signal screen shows 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 impossib le, the
watch keeps time within ±20 seconds a month at normal temperature.
• If y ou have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your tr ansmitter, current city code , DST
(summer time), and auto receive settings. The f ollowing are the initial factory defaults
for these settings.

T ransmitters
This watch is designed to receive the time calibration signal tr ansmitted from Rugby ,
England and the signal from Mainflingen, Germany . Y ou can select either one of the
transmitters, or y ou can configure the watch to automatically select the transmitter that
has the strongest signal.
• The follo wing explains how the watch determines which transmitter it should chec k
first while the watch is configured for auto tr ansmitter search (
A/T).
In this case:
The first signal auto search operation
after factory default settings are in eff ect,
or after the city code has been changed
Any case other than the abov e.
The watch does this:
1. Checks the Rugby signal first.
2. If the Rugby signal cannot be received,
checks the Mainflingen signal.
1. Checks the last successfully received
signal first.
2. If the last successfully received signal
cannot be received, checks the other
signal.

Timekeeping
• Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased b y 1. In the range of 00 to 29, the seconds are
reset to
00 without changing the minutes.
• The day of the week is automatically displa yed in accordance with the date (year ,
month, and day) settings .
• The year can be set in the range of 2000 to 2039.
• The watch ’s built-in full automatic calendar mak es allowances for diff erent month
lengths and leap years . Once y ou set the date, there should be no reason to change
it e xcept after you have the watch’s batter y replaced.
• The current time f or all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Greenwich Mean Time (GMT) differential for each
city , based on your Home City time setting.
• GMT differential is calculated b y this watch based on Universal Time Coordinated
(UTC*) data.
* The letters “UTC ” stands for “ Universal Time Coordinated,” 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. The reference point for UTC is
Greenwich, England.
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 P (PM) indicator appears on the display f or times in the
range of noon to 11:59 p .m. and no indicator appears f or times in the range of
midnight to 11:59 a.m.
• With the 24-hour format, times are display ed in the range of 0:00 to 23:59. The
indicator 24 indicates the 24-hour format.
Illumination Precautions
The watch has an EL (electro-luminescent) panel that causes the entire displa y to
glow for easy reading in the dark.
In any mode, press B to illuminate the displa y for about one second.
• The electro-luminescent panel that provides illumination loses po wer after very long
use.
• Illumination ma y be hard to see when viewed under direct sunlight.
• The watch may emit an audib le sound whenev er the display is illuminated. This is
due to vibration of the EL panel used f or illumination, and does not indicate
malfunction.
• Illumination turns off automatically whenever an alarm sounds .
• Frequent use of illumination runs do wn the battery.
