Operation Guide 2734 58 3748 9
•The current time setting in accordance with the time calibration signal takes priority over any time settings you make.
•The watch is designed to automatically update the date and day of the week for the period January 1, 2000 to December 31, 2039. Setting of the date by the time calibration signal cannot be performed starting from January 1, 2040.
•This watch can receive signals that differentiate between leap years and
•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 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 (A/T).
Module 2734 and 3749
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. |
Module 2758 and 3748 |
|
|
|
| |
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, or |
| 3749) will be engraved inside the box on the back |
2758 | 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: | 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
indicates that you cannot specify a transmitter. 3.Press A twice 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
•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

•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.
