Confi guring Home City Settings
For your Home City, you should select one of the 24 cities in the City Code Table
that is in the same time zone as your current location. You also need to select either
standard time (STD) or daylight saving time (DST) in accordance with the use of
daylight saving time in your country or geographic area.
If you are in an area where time calibration signal reception is possible, setting
the wrong city as your Home City can make reception impossible or may result in
incorrect time settings.

Regular Timekeeping and World Time
Regular timekeeping is performed in accordance with the current Home City time,
which is determined by your current Home City and its daylight saving time setting.
Based on your Home City time, the watch also keeps track of the current time in 24
cities around the world (World Time).
If your currently selected Home City is one that supports time calibration signal
x
reception, the time setting will be automatically adjusted whenever a signal is
received.
If your Home City does not support signal reception, regular timekeeping is
x
performed like a normal quartz timepiece.
Important!
Whenever you are in an area where a signal cannot be received or if your Home
x
City does not support signal reception, you will need to confi gure time settings
manually. See “Confi guring Current Time Settings Manually” (page E-46).

Radio-controlled Atomic Timekeeping Precautions
Strong electrostatic charge can result in the wrong time setting.

x
setting to be off by up to one second.

with the precision noted in “Specifi cations” (page E-60).
The receive operation is disabled under any of the following conditions.
