About Auto Receive
The watch receives the time calibration signal automatically up to 6 times a day (5 times a day for the Chinese calibration signal). When any auto receive is successful, the remaining auto receive operations are not performed. The reception schedule (calibration times) depends on your currently selected Home City, and whether standard time or Daylight Saving Time is selected for your Home City.

Note
•When a calibration time is reached, the watch 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 you are configuring settings.
•Auto receive of the calibration signal is designed to be performed early in the morning, while you sleep (provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove the watch from your wrist, and put it in a location where it can receive the signal easily.
•Remember that reception of the calibration signal depends on the current time in the Timekeeping Mode. The receive operation will be performed whenever the display shows any one of the calibration times, regardless of whether or not the displayed time actually is the correct time.
To perform manual receive
1. While in the Timekeeping Mode or Battery/Receive
Receiving | Mode, hold down Cfor about two seconds. |
| • The second hand will move to READY (R) and signal |
| reception will start. |
| • The digital display will go blank at this time. |
| • The second hand will indicate the current reception |
| status. |
| READY (or R) : Unstable |
| WORK (or W) : Stable |
| • Keep the watch in a location where reception is stable |
| while a receive operation is in progress. |
READY (or R) | • Signal reception takes from three to eight minutes, but |
| in some cases it can take as long as 16 minutes. Take |
| care that you do not perform any button operations or |
| move the watch during this time. |
•Even under optimum reception conditions, it can take about 30 seconds for reception to stabilize.
|
|
•Check the second hand position to find out the status of a receive operation and to determine the best location for signal reception.
•Note that weather, the time of day, surroundings, and other factors all can affect reception.
Note
To cancel an ongoing signal receive operation, press any button.
When reception is successful
•“GET” appears when reception is complete, and the
watch adjusts its current time setting.
• To return to the Timekeeping Mode after “GET” appears, press Bor C, or do not perform any operation for one or two minutes.
• The receive successful indicator is displayed after a successful receive operation.
When reception fails
•The watch displays “ERROR” without adjusting the current time setting.
•To return to the Timekeeping Mode after “ERROR” appears, press Bor C, or do not perform any operation for one or two minutes.
•Once any receive operation is successful, the receive successful indicator will remain on the display for the rest of the day, even if other receive operations fail.
To turn auto receive on and off
|
|
| 1. In the Timekeeping Mode, press B to enter the | |
|
|
| Battery/Receive Mode. | |
|
|
| 2. Press Cto display the date and time of the last | |
|
|
| successful signal reception. | |
|
|
| 3. Hold down A until the current auto receive setting (ON | |
|
|
| or OFF) starts to flash. This is the setting screen. | |
