Signal Reception Troubleshooting
Check the following points whenever you experience problems with signal reception.
For further information, see “Important!” under “Time Calibration Signal Reception”
and “Radio-controlled Atomic Timekeeping Precautions”.
World Time
The World Time Mode digitally displays the current time in
48 cities (29 time zones) around the world.
If the current time shown for a city is wrong, check your
Home City time settings and make the necessary
changes.
The watch will perform a signal reception even if it is in
the World Time Mode when a calibration time is
reached. If this happens, the World Time Mode time
settings will be adjusted in accordance with the
Timekeeping Mode’s Home City time.
All of the operations in this section are performed in the
World Time Mode, which you enter by pressing C.
