How a Radio-controlled Watch Works

What is a radio-controlled watch?
Your radio-controlled watch is designed to receive a time calibration signal that contains standard time data, and adjust its current time setting accordingly.
Signal is received by
Transmitter Long-wave time
Cesium
atomic clock
After the watch receives the Standard Time signal, it performs internal calculations to determine the current time. Because of this, there may be an error of up to one second in the displayed time.

Receiving the Calibration Signal
There are two methods you can use in order to receive the time calibration signal.
Auto receive (Reception is performed automatically at midnight, 1:00, 2:00, 3:00, and 4:00 each morning.)
Manual receive (You initiate reception using a button operation.)
If reception is not successful for any of the normal auto receive operations shown above, auto receive is performed one more time at 5:00 a.m.
The watch is set up for auto receive at the factory, so all you need to do is to place it in a location that allows good reception each night.
To position the watch for optimum reception
Remove the watch from your wrist and place it somewhere so its top (12 o’clock, where the antenna is located) is facing approximately in the direction of the signal transmitter. Keep it away from metal objects.

built-in antenna.
Decode
Watch decodes received data and converts it to time data.
Time is adjusted according to time data.
Calibration Signal
The Japanese calibration signal (Call Sign: JJY) is maintained by the National Institute of Information and Communications Technology (NICT). It is transmitted 24 hours a day from the Mt. Otakadoya transmitter (40 kHz) located in Tamura-gun, Fukushima Prefecture, and from the Mt. Hagane transmitter (60 kHz) located on the border between Saga Prefecture and Fukuoka Prefecture.
The U.S. calibration signal (Call Sign: WWVB) is transmitted by the National Institute of Standards and technology from Fort Collins, Colorado.
The time data of the Japanese calibration signal (Call Sign: JJY) is maintained by the Japan Standard Time Group of the National Institute of Information and Communications Technology (NICT). Note that transmission of the standard wave may be interrupted occasionally due to maintenance, lightning, etc. For more information, visit the website of the Japan Standard Time Group of the National Institute of Information and Communications Technology (NICT) at the following URL.
http://jjy.nict.go.jp
Note that the above URL is subject to change.
Time Required for Reception
Signal reception takes anywhere from about two to seven minutes. In cases where receipt is not possible from the transmitter from which the signal was last received, reception may take up to 14 minutes.
To perform signal reception manually
In the Timekeeping Mode, hold down the about two seconds.
The watch will beep and reception will start. The receive indicator cycles from “Unstable” through “Stable” as shown below while reception is in progress. How far it cycles depends on the signal strength.
To interrupt reception
Press the
All other buttons besides D are disabled during signal reception.
When reception is successful
The watch terminates reception and adjusts the current time. Next it beeps and then displays the date and time the adjustment was performed. The receive indicator on the display also indicates successful signal reception. The indicator is cleared from the display each day at midnight.
When reception fails (ERR Indicator)
In the case of an error, the watch will not adjust its current time setting, but display “ERR” instead.
The display will return to the normal timekeeping screen automatically if you do not perform any operation for about one or two minutes.

Troubleshooting
1. The watch cannot receive the time calibration signal.
Is the signal being transmitted? Though the time data of the Japanese calibration signal (Call Sign: JJY) is maintained by the Japan Standard Time Group of the National Institute of Information and Communications Technology (NICT), it may be interrupted sometimes for periodic maintenance work, or because of lightning or other problems.
Are you within the reception range of a transmitter? See Reception Ranges for information about areas where the watch can receive the signal.
Is there something in the immediate area that may be interfering with reception? Even if you are within the reception range of a transmitter, objects between you and the transmitter or electrical noise can interfere with reception. Avoid such areas during signal reception. See Location.
Do you have the correct Home City code selected? Remember that auto receive is not performed unless one of the following is selected as the Home City: TYO (Tokyo), SEL (Seoul), HKG (Hong Kong), YVR (Vancouver), LAX (Los Angeles), YEA (Edmonton), DEN (Denver), MEX (Mexico), YWG (Winnipeg), CHI (Chicago), MIA (Miami), YTO (Toronto), NYC (New York), YHZ (Halifax), or YYT (St. Johns). Correctly select your Home City using the procedure under Configuring Home Time Settings”.
Is auto receive turned off? Use the procedure under Configuring Auto Receive Settings to turn on auto receive.
3. Press the
4. When the setting is the
Press the D button to

The display also will exit the setting screen automatically if you do not perform any operation for about two or three minutes.
Is the watch in any mode other than the Timekeeping Mode or World Time Mode during the auto receive times (midnight, 1:00 a.m., 2:00 a.m., 3:00 a.m., 4:00 a.m., and 5:00 a.m.)? Auto receive is performed only when the watch is in the Timekeeping Mode or World Time Mode. It is not performed if the watch is in any other mode.
Is a timer operation in progress? Calibration signal reception is disabled while a timer operation is in progress. Because of this, you should avoid performing timer operations during the timeframes that signal reception is performed, or perform manual receive after your timer operation is complete.
2. Time calibration signal reception is successful, but the hourly time signal and current time are off slightly.
After the watch receives the time calibration signal, it performs an internal decoding process before updating its time setting. Because of this, the time setting may be off slightly (within one second).
3. Time calibration signal reception is successful, but the current time is one hour fast.
Do you have summer time (DST) turned on? Use the procedure under Configuring Home Time Settings to select either AUTO or OFF for the summer time setting.

4. Time calibration signal reception is successful, but the current time setting is wrong.
Is TYO (Tokyo) or HKG (Hong Kong) selected for your Home City? Correctly select your Home City using the procedure under Configuring Home Time Settings.
5. The digital time and analog time are different.
Normally, the received time calibration data is used to adjust the digital display time, and then the analog hands are adjusted to match the digital time. If the hands are misaligned for some reason, they will not indicate the correct time. If this happens, use the procedure under Setting the Analog Time Manually to adjust the analog time.
6. Can you configure auto receive settings?
Remember that auto receive is not performed unless one of the following is selected as the Home City: TYO (Tokyo), SEL (Seoul), HKG (Hong Kong), YVR (Vancouver), LAX (Los Angeles), YEA (Edmonton), DEN (Denver), MEX (Mexico), YWG (Winnipeg), CHI (Chicago), MIA (Miami), YTO (Toronto), NYC (New York), YHZ (Halifax), or YYT (St. Johns). Correctly select your Home City using the procedure under Configuring Home Time Settings”.
7. What time is auto receive performed?
Auto receive is performed in the middle of the night, when reception conditions are best. Before going to bed at night, place the watch near a window, with 12 oclock facing in the general direction of the transmitter.
Calibration Signal Reception Precautions
Auto receive can be performed while the watch is in the Timekeeping Mode or World Time Mode only.
Signal reception is not possible while a timer operation is in progress.
Receipt of a calibration signal causes the digital time to be adjusted first, followed by adjustment of the analog time. In order to ensure correct correction of the analog time, be sure to match the analog time with the digital time before performing a signal receive operation.
Operating any button while auto receive is in progress will cause the watch to beep and then exit the receive operation.
Make sure you are within the range of the calibration signal transmitter before performing the reception operation. Remember that geographic contours, nearby buildings, the season, the time of day, can even make reception impossible even when you are within range of the transmitter.
Proper reception may be impossible if there is something blocking the signal. If reception is unsuccessful, try again.
This watch is designed to adjust its current time setting in accordance with the calibration signal transmitted in Japan and the United States only. Note that you will need to make your own adjustments when using this watch outside of Japan or the United States, or in any area that is outside the range of one of the receivable time calibration signal transmitters.
When the watch is unable to adjust its time signal using the calibration signal for some reason, timekeeping accuracy is within
±15 seconds per month.
Strong electrostatic charge can cause timekeeping error.
Signal reception is cancelled if an alert operation starts while it is
being performed.
The watchs calendar shows dates up to the year 2099. Attempting a receive operation after that causes an error.
8. How can I perform manual receive?
Hold down the lower right D button for about two seconds. The watch will beep to indicate that manual receive has started. Place it near a window, with 12 oclock facing in the general direction of the transmitter.
9. How can I view the last reception date and time?
In the Timekeeping Mode, press the lower right D button. This will display the date and time that the time calibration signal was last received successfully. To return to the Timekeeping Mode, press the D button again.
If you cannot receive the calibration signal or if the current time setting is incorrect after signal reception, check the current setup of the watch.
