Configuring Auto Receive Settings
Use the procedure below to turn auto calibration signal reception on and off.
•For information about selecting a Home City, see “Configuring Home Time Settings”.
•The following procedure can be performed when any one of the following city codes is selected as the Home Time: TYO, SEL, HKG, YVR, LAX, YEA, DEN, MEX, YWG, CHI, MIA, YTO, NYC, YHZ, or YYT.
1. In the Timekeeping Mode, press the D button to display the last reception date and time.
• This displays the last
reception date and timeReception Time screen.
•The display will return to the normal timekeeping screen automatically if you do not perform any operation for about one or two minutes.
2. Hold down the Abutton for about two seconds until the current auto receive setting flashes on the display.
•This is the auto receive setting screen.
3. Press the Dbutton to toggle the setting between ON and OFF.
4. When the setting is the way you want, press the
Abutton to exit the setting screen.
•Press the D button to return to the Timekeeping Mode.
•The display also will exit the setting screen automatically if you do not perform any operation for about two or three minutes.
•ON
Selecting this setting turns on auto receive and auto transmitter selection. The watch selects either the Otakadoya Mountain signal (40 kHz) or the Hagane Mountain signal (60 kHz) automatically, whichever is strongest.
•The transmitter from which a signal was last successfully received will be given priority for the next auto receive operation.
•OFF
Selecting this setting turns off auto receive and auto transmitter selection.
When the Home City is YVR, LAX, YEA, DEN, MEX, YWG, CHI, MIA, YTO, NYC, YHZ, or YYT
•ON
Selecting this setting turns on auto receive. The watch always receives the Fort Collins signal.
•OFF
Selecting this setting turns off auto receive.
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 watch’s calendar shows dates up to the year 2099. Attempting a receive operation after that causes an error.
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. John’s). 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.
•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. John’s). 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 o’clock facing in the general direction of the transmitter.
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 o’clock 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 Dbutton. This will display the date and time that the time calibration signal was last received successfully. To return to the Timekeeping Mode, press the Dbutton 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.
