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”.
Dual Time
The Dual Time Mode shows you the current time in 29
time zones around the world.
• If the current time shown for a time zone is wrong, check
your Home Time Zone time settings and make the
necessary changes.
• All of the operations in this section are performed in the
Dual Time Mode, which you enter by pressing B.
To view the time in another Time Zone
1. In the Dual Time Mode, press C to display the UTC differential value of the
currently selected time zone for about two seconds.
2. To change the UTC differential value, press C while a UTC differential value is on
the display to scroll eastward through time zones.
• Note that if you do not press C to scroll within two seconds after displaying a
UTC differential value, the display will change automatically to the current time
based on the currently displayed UTC differential value.
3. When the UTC differential value you want is on the display, do not perform any
button operation for about two seconds. This will cause the current time to appear,
which will be based on the UTC differential value you selected.
