Transmitters
The time calibration signal received by this watch depends on the currently
selected Home City code (page E-13).
• When a U.S. time zone is selected, the watch receives the time calibration
signal transmitted from the United States (Fort Collins).
• When a Japanese time zone is selected, the watch receives the time
calibration signal transmitted from Japan (Fukushima and Fukuoka/Saga).
• When a European time zone is selected, the watch receives the time
calibration signals transmitted from Germany (Mainflingen) and England
(Anthorn).
• When a China time zone is selected, the watch receives the time calibration
signals transmitted from China (Shangqiu City).
• When your Home City is LON, PAR, BER, or ATH (which can receive both
the Anthorn and Mainflingen signals), the watch first tries to pick up the
signal it last successfully received. If that fails, it tries the other signal. For
the first receive after you select your Home City, the watch tries the nearest
signal first (Anthorn for LON, Mainflingen for PAR, BER, and ATH).
