Operation Guide 3390
Location
Reception is difficult and may even be impossible in the locations described below. Avoid such locations when performing signal reception.
•You should think of your watch operating like a radio or TV when it is receiving the calibration signal.
Receiving the Calibration Signal
There are two methods you can use to receive the time calibration signal.
•Auto receive (Reception is performed automatically at midnight, 2:00, 3:00 and 4:00 each morning.)
•Manual receive (You initiate reception using a button operation.)
•If reception is not successful for any of the normal auto receive operations shown above, auto receive is performed one more time at 5:00 a.m.
•The watch is set up for auto receive at the factory, so all you need to do is to place it in a location that allows good reception each night.
❚Time Required for Reception
A calibration signal receive operation takes anywhere from about two to six minutes.
•Note that when “AUTO” (Auto Select) is specified as the transmitter selection mode, signal reception can take up to 12 minutes.
•See “Configuring Auto Receive Settings” for more information.
❚To perform manual receive
❚Receive Indicator
The receive indicator cycles from “Unstable” through “Stable” as shown below while reception is in progress. How far it cycles depends on the signal strength. Keep the watch in a location where reception is stable while reception is in progress.

Reception Error (ERR Indicator)
•Even under optimum reception conditions, it can take about 10 seconds for reception to stabilize.
•Use the receive indicator to check reception status and to determine the best location for signal reception.
•Note that weather, the time of day, surroundings, and other factors can all affect reception.
If you are experiencing problems with reception, move away from the types of locations described above to a location with better reception, and try again.
•Orienting the watch so it is sideways to the transmitter makes it more difficult to receive the signal.
•Do not move the watch while it is receiving the calibration signal.
The watch does not adjust its current time setting, and displays “ERR” when signal reception is unsuccessful for some reason.
•The watch will return to the Timekeeping Mode automatically if you do not perform any operation for about one or two minutes.
