8-8. TIME CALIBRATION SIGNAL TEST
A signal reception failure may be caused by a number of reasons.
Follow the steps shown in the flowchart below to run the signal receiving test.
START
Check the Receiving Station
MANUAL Reception
Reception OK?
YES
OK
Insufficient Signal
The time calibration signal may not be properly received under the following conditions.
• The strength of the signal has changed due to season or time of day
• The watch is placed in the reinforced concrete building
• There is a broadcasting station nearby
• Strong enough signal cannot be received due to the position of the watch
The real signal in China differs from the signal for the test with TEM cell.
* To check the real signal reception in China, perform the inspection in the normal mode.
* To check the signal reception for China with TEM cell, perform the inspection in the Test Mode.
8-8-1. MANUAL/AUTO Reception
To change the signal station, you may easily do so
by using the test mode in P.22 "CONFIGURING
HOME CITY".
For details of MANUAL and AUTO reception modes,
refer to the Operation Guide.
MANUAL Reception
While on the Timekeeping mode, hold down
seconds. After the second hand displays the last signal reception result, the second hand will move to "R"
(19-second position). The second hand will be at "W" (23-second position) while receiving signal.
When the signal is received successfully, the second hand will move to "Y"(7-second position).
When the reception fails, the second hand will move to "N"(11-second position).
After the result is indicated for one second, the watch will return to the Timekeeping mode.
* Press any button to end the reception or the reception result display and return to the Timekeeping mode.
AUTO Reception
Turn on the AUTO Reception setting. When AUTO Reception is turned ON, the calibration signal is
automatically received up to 6 times from midnight through early morning.
(If reception is successful once, the subsequent AUTO reception will not be conducted on the same
day.)
* To check whether the calibration signal was received successfully, press
ing mode and determine the result by the position of the second hand.
(If successful, the second hand indicates the "Y" (7-second position) and if failed the "N" (11-second
position))
Perform the test in "MANUAL Reception"
