Signal Level Indicator
During calibration signal reception, the signal level indicator displays the
signal level as shown below.
Weak (Unstable)
Strong (Stable)
The level indication will change in accordance with reception conditions
while reception is being performed.
As you watch the indicator, keep the watch in a location that best
maintains stable reception.
•
Even under optimum reception conditions, it can take about 10
seconds for reception to stabilize.
•
Note that weather, the time of day, surroundings, and other factors all
can affect reception.

Radio-controlled Atomic Timekeeping Precautions
•
Strong electrostatic charge can result in the wrong time setting.
•
The receive operation is disabled under any of the following conditions.
– While power is at Level 3 (
L
) or lower (page E-15)
– While the watch is in the power recovery mode (page E-17)
– When the watch is in the function sleep state (“Power Saving”, page E-19)
– While the crown is pulled out
– While barometric pressure change indicator is being measured
– While a countdown timer operation is in progress (page E-90)
•
A receive operation is cancelled if an alarm sounds while it is being performed.
•
The watch is designed to update the date and day of the week automatically for the period January 1,
2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed
starting from January 1, 2100.
•
Even if a receive operation is successful, certain conditions can cause the time setting to be off by up
to one second.
•
If you are in an area where signal reception is not possible, the watch keeps time with the precision
noted in “Specifi cations”.
•
The Home City setting reverts to the initial default of
TYO
(Tokyo) whenever the battery power level
drops to Level 5 or when you have the rechargeable battery replaced. If this happens, change the
Home City to the setting you want (page E-34).
