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.

Setting	Initial Factory Default
Transmitter	A/T
City code	LON (London) (Modules 2734, 3749, and 4774)
	BER (Berlin) (Modules 2758, 3748, and 4773)
DST (summer time)	A	(Auto switching)
	DST
Auto receive	ON	(Auto receive)
	R/C

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 (A/T).

Modules 2734, 3749, and 4774

In this case:	The watch does this:
The first signal auto search operation	1. Checks the Rugby signal first.
after factory default settings are in effect,	2. If the Rugby signal cannot be received,
or after the city code has been changed	checks the Mainflingen signal.
Any case other than the above.	1. Checks the last successfully received
	signal first.
	2. If the last successfully received signal
	cannot be received, checks the other
	signal.
Modules 2758, 3748, and 4773
In this case:	The watch does this:
The first signal auto search operation	1. Checks the Mainflingen signal first.
after factory default settings are in effect,	2. If the Mainflingen signal cannot be
or after the city code has been changed	received, checks the Rugby signal.
Any case other than the above.	1. Checks the last successfully received
	signal first.
	2. If the last successfully received signal
	cannot be received, checks the other
	signal.

•Since the watch checks signals from both transmitters when A/T is selected as the 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 Auntil the transmitter indicator starts to flash, which indicates the setting screen.

2. Use Dto scroll through available transmitter settings until the one you want to select is displayed.

To set up the watch to do this:	Select this transmitter setting:
Automatically select the Rugby or Mainflingen signal	A/T
Receive the Mainflingen signal	DCF
Receive the Rugby signal	MSF

•Note that ---appears in place of the transmitter indicator when any city code

besides LON, PAR, BER, or ATH is selected as the Home City code. This indicates that you cannot specify a transmitter.

3.Press Atwice to exit the setting screen.

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.
