Configuring Auto Receive Settings
Use the procedure below to turn auto calibration signal reception on and off.
•The following is the procedure for configuring auto receive settings when TYO (Tokyo) is selected as the Home City.

(6 times)
2. Hold down the E button for about two seconds until the current On/OFF setting starts to flash on the display. This is the setting screen.
(2 seconds)
4. When the setting is the way you want, press the E button to exit the setting screen and return to the reception date and time 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.
When the time zone setting is TYO
•On
Selecting this setting turns on auto receive and auto transmitter selection. The watch automatically selects either the Otakadoya Mountain signal (40kHz) or the Hagane Mountain signal (60kHz), whichever is strongest.
•OFF
Selecting this setting turns off auto receive and auto transmitter selection.
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 when any one of the following conditions exists.
•Timer operation in progress
•Battery at Level 3 or Level 4
•Recover indicator (RECOV) displayed
•While altitude recording is being performed (Manual signal reception can still be performed.)
•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 only. Note that you will need to make your own adjustments when using this watch outside of Japan, 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 is 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
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 sometimes be interrupted 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” for more information.
•Do you have the correct Home City code selected?
Signal reception is not performed when the Home City setting is any city code other than TYO (Tokyo). For details about setting the correct Home City, see “To configure Home City settings”.
•Is auto receive turned off?
Use the procedure under “Configuring Auto Receive Settings” to turn on auto receive.
•Barometric pressure readings (at the top of each
•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.
Time calibration signal reception is successful, but the hourly time signal and current time are slightly off.
•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 slightly off (within one second).
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 “To configure Home City settings” to change the summer time setting to OFF.
Time calibration signal reception is successful, but the current time setting is wrong.
•Is TYO (Tokyo) selected for your Home City? For details about setting the correct Home City, see “To configure Home City settings”.
Can you configure auto receive settings?
•Auto receive settings cannot be configured when the Home City setting is any city code other than TYO (Tokyo). For details about setting the correct Home City, see “To configure Home City settings”.
When 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.
How can I view the last reception date and time?
•In the Timekeeping Mode, press the D button (lower left) six times to enter the Receive Mode.
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.
How can I perform manual receive?
•In the Receive Mode, hold down the C button (lower right) 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.
•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.
•The following are the watch’s factory default settings, which are configured automatically whenever you have the battery of the watch replaced.
