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.

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.

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:

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.
