Operation Guide COMBIWVGE1
• 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 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 within ±20 seconds a month at normal temperature.
• If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your transmitter, current city code, DST
(summer time), and auto receive settings. The following are the initial factory defaults
for these settings.

Transmitters
This watch is designed to receive the time calibration signal transmitted from Rugby,
England and the signal from Mainflingen, Germany. You can select either one of the
transmitters, or you can configure the watch to automatically select the transmitter that
has the strongest signal.
• The following explains how the watch determines which transmitter it should check
first while the watch is configured for auto transmitter search (

• Since the watch checks signals from both transmitters when
transmitter setting, the signal receive operation can take as long as 12 minutes.
• To find out the module number of your watch, look at its
2734
back cover. The Module number (2734, 2758, 3748,
3749, 4773, or 4774) will be engraved inside the box on
2758
the back cover.
To select a transmitter
1. In the Timekeeping Mode, hold down A until the
transmitter indicator starts to flash, which indicates the
setting screen.
2. Use D to scroll through available transmitter settings
until the one you want to select is displayed.
To set up the watch to do this:

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 automatically displayed 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 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 current time for 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 by 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 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. The
indicator 24 indicates the 24-hour format.

Illumination Precautions
The watch has 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 one second.
• 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.
