Reception is difficult and may even be impossible in the locations described below. Avoid such locations when performing signal reception.
•You should think of your watch as operating like a radio or TV when it is receiving the calibration signal.
Among or near buildings | Near |
Calibration Signal Reception Precautions
• Auto receive is disabled while the watch is in the Chronograph |
Mode. |
• 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 a calibration signal |
transmitter before performing the receive operation. Remember |
that geographic contours, nearby buildings, the season, or the |
time of day can 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 using the calibration |
signal for some reason, timekeeping accuracy is within ±20 |
Troubleshooting
1. The watch cannot receive the time calibration 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. |
• Are you within the reception range of a transmitter? |
See “Reception Ranges” for information about areas where the |
watch can receive the signal. |
• Do you have the correct Home City code selected? |
Remember that auto receive is not performed unless TYO |
(Tokyo), HKG (Hong Kong), NYC (New York), CHI (Chicago), |
DEN (Denver), LAX (Los Angeles), ANC (Anchorage), or HNL |
(Honolulu) is selected as the Home City. Select the correct Home |
City code using the procedure under “Changing the Home City |
Setting”. |
• Is the signal being transmitted? |
Though the time data of the Japanese calibration signal (Call |
2.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 off slightly (within one second).
3.Time calibration signal reception is successful, but the current time setting is wrong.
•Is the correct city code selected for your Home City? Select the correct Home City code using the procedure under “Changing the Home City Setting”.

seconds per month. |
• Strong electrostatic charge can cause timekeeping error. |
• Receive is cancelled if an alarm 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. |

Technology (NICT), it sometimes may be interrupted for periodic |
maintenance work, or because of lightning or other problems. |
If you are experiencing problems with reception, move away from the types of locations described above to a location with better reception, and try again.
