Important!
•
Normally, your watch should show the correct time as soon as you select your Home
City code. If it does not, it should adjust automatically after the next auto receive
operation (in the middle of the night). You can also perform manual receive or you
can set the time manually.
•
The watch will receive the time calibration signal automatically from the applicable
transmitter (in the middle of the night) and update its settings accordingly. For
information about the relationship between city codes and transmitters, see “Home
City Codes and Transmitters”.

Under factory default settings, auto receive is turned off for all of the following city
codes: HNL (Honolulu), ANC (Anchorage), ATH (Athens), and MOW (Moscow). For
details about turning on auto receive for these city codes, see “To turn auto receive
on and off”.
