by a chargeable battery. Long-term storage of the watch can cause
the battery to run low, so be sure to expose the watch to light for
some time before using it for the first time. See Solar Charging for
more information.

When reception is complete (Signaled when the watch beeps.)
When the receive operation is successful, the indicator hand
moves to Y, the watch adjusts its time, and then the indicator
hand returns to its second hand operation after about one or two
minutes.
When the receive operation fails, the indicator hand moves to N
and then the watch returns to the unadjusted time after about one
or two minutes.
Reception Ranges
This watch is designed to receive the standard time calibration signal of Japan (JJY) or of the United States (WWVB). The signal that is
received depends on the current Home City setting.
For information about selecting a Home City, see Changing the Home City Setting. See the World Time City Code List for
information about city codes.

Certain conditions can make reception impossible even when the watch is within one of the reception ranges shown above.
Signals become weaker outside of the smaller circles indicated by dashed lines, so the reception environment has a greater effect on signal
reception.
The following also can affect signal reception: geographic contours, structures, weather, climate, time of day (afternoon, evening), noise.
Inside a vehicle
(automobile, train, plane, etc.)
Next to a household
appliance or office
equipment (TV, speaker, fax,
computer, cell phone, etc.)

When you are using the watch in an area that supports time
calibration signal reception, it will adjust the date automatically
for month lengths and leap years. If you use it in an area that
does not support signal reception, you will have to make
adjustments for month lengths and leap year manually.
