●Table of radio controlled time zones (city)

•The cities listed in the table below may be abbreviated or spelled out, depending on the model.

•The signal station is changed depending on the selected city.

•When you use the watch in a place which is not shown in the table below, set the time using the alternate time mode (A-TM).

•The time difference in the table below is based on the coordinated universal time (UTC).

•The stored setting for the presence of daylight savings radio signal is common to all regions in each radio signal zone.

Indication	City name	Time difference	Signal from...
LON	London	0	Germany
NYC	New York	−5		* Transmitter
CHI	Chicago	−6	U.S.A.

•The time in each city is calculated from the time difference from UTC.

•When the watch receives radio signal in a city or you correct the time of a city manually, the times in all other cities are corrected accordingly based on the time differences. (This also applies to A-TM.)

■ Receiving the radio signal

There are three ways to receive the radio signal.

This watch also incorporates a function to check last radio reception results. → pages 14 and 15

Reception method	Explanations
Automatic reception	Receives the signal at 2:00 a.m. every day. If reception is unsuccessful,
	the watch tries to receive at 3:00 a.m. and 4:00 a.m.
On demand	Receive the signal manually when you want to adjust the time
reception	and date. →page 24
Recovery automatic	Receives the signal automatically after charging when the watch
reception	stops due to insufficient charge.

• These reception operations take place only when the crown is in the closed position 0 and the watch is not moved.

•When the watch is in a low power state (second hand moving in two second intervals), radio reception will not be attempted.

Notes on the radio signal reception

•Radio signal reception cannot be deactivated.

•Even when this watch receives a radio signal successfully, the accuracy of the displayed time will be dependent on the reception environment and internal processing.

•If the watch is not able to receive the signal, it will operate normally within an accuracy range of ±15 seconds per month.

■ During radio reception:

Remove the watch and place it on a stable surface where it can receive the signal better, such as next to a window.

• The reception antenna is located at the 6:00 position of the watch. Place the watch with the 6:00 position facing toward the station.

•While the watch is receiving radio signals (the second hand indicates RX, H, M, or L), do not move the watch as a successful update will not be acheived.

Notes on the radio signal reception

■ Note on the radio signal

This watch receives the radio signal from the two signal stations located in U.S.A. or Germany and automatically adjusts the time and date.

The receivable signal stations are listed as follows:

Signal stations	Kind of the radio signal
Fort Collins station, Denver, Colorado State, U.S.A.	WWVB
Mainflingen station, southeast Frankfurt, Germany	DCF77

Notes on the radio signal reception

■ When signal reception is poor

Radio signal reception may be affected by the surrounding environment. High-tension wires nearby or windows containing wire meshes make it difficult to receive radio signal. In this case, you should find another suitable place considering the location of the transmitter station in your region. Then, place the watch at a window facing to the station and attempt manual reception. → pages 24 and 25

If the window contains wire screens, open the window or change the location of the watch.

Notes on the radio signal reception

■ Poor reception areas

It may be difficult to receive the radio signal properly under certain environmental conditions or in areas susceptible to radio noise.
