Operation Guide 3024
•Signal reception is normally better at night than during the day.
•Time calibration signal reception takes from two to five minutes. Take care that you do not perform any button operations or move the watch during this time.
•This watch is designed to pick up the time calibration signal transmitted from Fort Collins, Colorado (USA).
Reception Range
600 miles | 2,000 miles |
Fort Collins
•At distances further than about 600 miles (1,000 kilometers) from the transmitter, signal reception may not be possible during certain times of year or times of day. Radio interferance may also cause problems with reception.
•Even when the watch is within the reception range of the transmitter, signal reception is impossible if the signal is blocked by mountains or other geological formations between the watch and signal source.
•Signal reception is affected by weather, atmospheric conditions, and seasonal changes.
•See the information under “Signal Receive Troubleshooting” if you experience problems with time calibration signal reception.
About Auto Receive
When auto receive is turned on, the watch starts to receive the time calibration signal automatically when the time in the Timekeeping Mode reaches midnight, 1:00 a.m. , 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m. (calibration times).
When any auto receive is successful, the remaining auto receive operations are not performed.
Note
•Auto receive works only while the watch is in the Timekeeping Mode or World Time Mode. Auto receive is not performed if an auto receive time is reached while an alarm is sounding, while a countdown timer operation is in progress, or while a setting screen (a screen with a flashing setting) is on the display.
•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.
•When auto receive is turned on, the watch receives the calibration signal for two to five minutes everyday when the Timekeeping Mode time reaches each of the calibration times. Do not perform any button operation within five minutes before or after any one of the calibration times. Doing so can interfere with correct calibration.
•Remember that reception of the calibration signal depends on the time kept 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 Timekeeping Mode time is actually the correct time.
•If more than one auto receive is successful, the watch uses the data from the last successful receive to adjust settings. When only one reception is successful, the watch uses the data of the successful reception.
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 receive operations.
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 Cfor about two seconds until RC! appears on the display.
• Time calibration signal reception takes from two to five 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
Receiving indicator • To interrupt a receive operation and return to the Timekeeping Mode, press C.
•If the receive operation is unsuccessful, the message ERR appears on the display for about 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 C.
