Time Calibration Signal Reception
This watch is designed to pick up a time calibration signal and update its time setting
in accordance with the signal. There are two different methods you can use to receive
the signal: Auto Receive and Manual Receive. With Auto Receive, the watch
automatically receives the calibration signal four times each day and makes
appropriate adjustments. With Manual Receive, you perform a specific button
operation to receive the calibration signal.
•
This watch is able to receive the time calibration signal
transmitted from Fort Collins, Colorado. Under good
reception conditions, signal reception is possible within
a radius of about 2,000 miles (3,000 kilometers) from
the Fort Collins transmitter.
•
At distances further than about 600 miles (1,000
kilometers) from the Fort Collins transmitter, the signal
may become weak and reception may be impossible
under certain conditions.

•
This watch automatically receives a time calibration
signal in the middle of the night, when reception is best.
Note
•
If you are using the time calibration signal to set the time for this watch, be sure to
correctly set your Home City. Otherwise, there is the chance that the watch will not
set the correct time. See “Setting the Time and Date Manually” for details.
•
Note that signal reception is possible only when the watch is within range of a time
calibration signal transmitter, and a city code that supports signal reception is
selected as the Home City code.
•
The current time setting in accordance with the time calibration signal takes priority
over any time settings you make.
•
Auto receive is turned on when the watch is shipped from the factory.
•
See the information under “Time Calibration Signal Reception” if you experience
problems with time calibration signal reception.
