with signal reception.
• Calibration signal reception is disabled while a countdo wn timer operation is in

About Auto Receive
The watch receives the time calibr ation signal automatically up to six times a day (fiv e
times for the China signal). When any auto receiv e is successful, the remaining auto
receive operations are not perf ormed. The reception schedule (calibration times)
depends on your currently selected Home City , and whether standard time or Daylight
Saving Time is selected for y our Home City .

Note
• When a calibration time is reached, the w atch will receive the calibration signal only
if it is in either the Timekeeping Mode or World Time Mode. Reception is not
performed if a calibration time is reached while y ou are configuring settings.

morning, while you sleep (provided that the Timekeeping Mode time is set correctly).
Before going to bed f or the night, remove the watch from your wrist, and put it in a
location where it can receive the signal easily .
• The watch receiv es the calibration signal for two to 14 min utes ev eryday when the
time in the Timek eeping Mode reaches a calibration time. Do not perform any button
operation within 14 minutes bef ore or after the calibration times. Doing so can
interfere with correct calibr ation.
• Remember that reception of the calibration signal depends on the current time in
your Home City , as kept in the Timek eeping Mode.
T o perform manual receive

• If signal reception is unstable during reception, the left
dial hand may mov e betw een W ( WORK ) and
R ( READ Y).
• The hour and minute hands continue to k eep time
normally .

• Time calibration signal reception takes from tw o to
7 minutes, b ut in some cases it can take as long as
14 minutes. T ake care that you do not perf orm any
button operations or mo ve the watch during this time .
• When signal receive oper ation is successful, GET

shows the time and date of the successful operation.
The watch will adjust its time setting in accordance to
with the inf or mation provided by the signal.
• The watch will return to the Timekeeping Mode if you
press A or if you do not perf orm any operation for
about one or two minutes.
• ERR will appear on the upper displa y if the receive
operation is not successful. The watch will not adjust its
