2.What you should do next depends on whether you are using Auto Receive or Manual Receive.

ξAuto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive” on page E-21 for details.

ξManual Receive: Perform the operation under “To perform manual receive” on page E-22.

Auto Receive

ξWith Auto Receive, the watch performs the receive operation each day automatically up to three times between the hours of 2 a.m. and 4 a.m. (1 a.m. and 3 a.m. for the Chinese calibration signal). When any receive operation is successful, none of the other receive operations for that day are performed.

ξWhen a calibration time is reached, the watch will perform the receive operation only if it is in the regular timekeeping. The receive operation is not performed if a calibration time is reached while you are configuring settings.

E-21

To perform manual receive

1.In the regular timekeeping, keep Adepressed (for about two seconds) as the x Second Hand goes through the following sequence.

ξMoves to YES (Y) or NO (N) to indicate the last signal reception result, then to Receiving (RC).

2.The x Second Hand indicates the operations the watch is currently performing.

When the x Second

It means this:

Hand is pointed here:

Receiving (RC)

Reception is in progress.

 

 

YES (Y)

Reception was completed

successfully.

 

NO (N)

Reception failed for some reason.

 

 

ξWhen the receive operation is successful, the watch adjusts the time setting accordingly. It does not adjust the setting if the operation failed.

Note

ξTo interrupt a receive operation and return to the regular timekeeping, press any button.

To check the result of the latest receive operation

In the regular timekeeping, press A.

ξ The x Second Hand will move to YES (Y) for five seconds if the latest receive operation was successful, or NO (N) if it was not. After that, regular timekeeping will resume.

ξ You can return to the regular timekeeping manually by pressing Awhile the x Second Hand is pointing to YES (Y) or NO (N).

Note

ξThe x Second Hand will indicate NO (N) if you have adjusted the time setting manually since the latest receive operation.

Radio-controlled Atomic Timekeeping Precautions

ξStrong electrostatic charge can result in the wrong time setting.

ξEven if a receive operation is successful, certain conditions can cause the time setting to be off by up to one second.

ξIf you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Specifications” (page E-46).

ξThe receive operation is disabled under any of the following conditions.

−While power is at Level 2 or lower (page E-12)

−When the watch is in the function sleep state (“Power Saving”, page E-15)

−While the b Ornament is moving (page E-32)
