Operation Guide 3772
•Signal reception is normally better at night than during the day.
•Time calibration signal reception takes from two to seven minutes, but in some cases it can take as long as 14 minutes. Take care that you do not perform any button operations or move the watch during this time.

Fort Collins
•Under good reception conditions, signal reception is possible within a radius of about 2,000 miles (3,000 kilometers) from the Fort Collins transmitter.
•At distances further than about 600 miles (1,000 kilometers) from the Fort Collins transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.
•See the information under “Signal Reception Troubleshooting” if you experience problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch automatically starts to receive the time calibration signal when the time in the Timekeeping Mode reaches 0:00 a.m., 1:00 a.m., 2:00 a.m., 3:00 a.m., and 4:00 a.m. each day (calibration times). The watch will also perform an additional auto receive at 5:00 a.m. if none of the regularly scheduled auto receive operations are successful.
When any auto receive is successful, the remaining auto receive operations are not performed.
Note
•Auto receive is performed only if the watch is in the Timekeeping Mode or World Time Mode when one of the calibration times is reached. It is not performed if a calibration time is reached while an alarm is sounding, or while you are configuring settings (while settings are flashing on the display).
•Auto receipt 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 easily receive the signal.
•When auto receive is turned on, the watch receives the calibration signal for two to seven minutes everyday when the time in the Timekeeping Mode reaches each of the five calibration times. Do not perform any button operation within seven minutes before or after any of the five calibration times. Doing so can interfere with correct calibration.
•Remember that reception of the calibration signal depends on the time kept in the digital display. Reception will be performed whenever the display shows one of the five calibration times, regardless of whether or not the displayed time is actually the correct time.
•Calibration signal reception is disabled while a countdown timer operation is in progress.
About the Receiving Indicator
The receiving indicator shows the strength of the calibration signal being received. For best reception, be sure to keep the watch in a location where signal strength is strongest.
Receiving indicator
Weak | Strong |
(Level 0) | (Level 3) |
•Even in an area where signal strength is strong, it takes about 10 seconds for signal reception to stabilize enough for the receiving indicator to indicate signal strength.
•Use the receiving indicator as a guide for checking signal strength and for finding the best location for the watch during signal reception.
•The Level 3 receiving indicator remains on the display in all modes following reception of the time calibration signal and calibration of the watch’s time setting. The Level 3 receiving indicator is not displayed if signal reception was unsuccessful or after manual adjustment of the current time setting.
•The Level 3 receiving indicator indicates that at least one of the five calibration signal receive operations was successful. Note, however, that the Level 3 receiving indicator is cleared from the display at 0:00 a.m. each day.
To perform manual receive
1. Place the watch on a stable surface so its top (12 o’clock side) is facing towards a window.
2. In the Timekeeping Mode, hold down Dfor about two seconds until the watch beeps.
3. After you release Dthe display will show the current time and the letters RC!. This indicates that signal reception is in progress.
•Time calibration signal reception normally takes from two to seven minutes. Take care that you do not perform any button operations or move the watch during this time.
•After signal reception is complete, the display of the watch changes to the last signal screen.
Note
•To interrupt a reception and return to the Timekeeping Mode, press D.
•If reception is unsuccessful, the message ERR appears on the display for one or two minutes. After that, the watch returns to the Timekeeping Mode.
•You can also change from the last signal or ERR screen to the normal timekeeping screen by pressing D.
•Calibration signal reception is disabled while a countdown timer operation is in progress.
To turn auto receive on and off
1. In the Timekeeping Mode, press D to display the last signal screen.
• The watch will automatically return to the Timekeeping Mode if you do not perform any button operation for one or two minutes after displaying the last signal screen.
2. Hold down A until the current auto receive setting
flashes on the display. This is the setting screen.

3.Use Dto turn auto receive on (ON) or off (OFF).
4.Press Ato exit the setting screen.
•To return to the Timekeeping Mode from the last signal screen, press D.
•For information about city codes that support signal reception, see “To set your Home City”.
