Operation Guide 3311/3356

Troubleshooting

The watch cannot receive the time calibration signal.

•Is the signal being transmitted?

Though the Japanese calibration signal (Call Sign: JJY) is continually transmitted by the National Institute of Information and Communications Technology (NICT) in theory, it may sometimes be interrupted for periodic maintenance work, or because of lightening or other problems.

•Are you within the reception range of a transmitter?

See “Reception Range” 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? Remember that auto receive is not performed unless TYO (Japan), NYC (New York), CHI (Chicago), DEN (Denver), or LAX (Los Angeles) is selected as the Home City. Select the correct Home City code using the procedure under “Selecting Your Home City”.

•Is auto receive turned off (OF)?

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.

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 (ON)?

Use the procedure under “Configuring Summer Time (Daylight Saving Time) Settings” to turn off summer time.

Time calibration signal reception is successful, but the current time setting is wrong.

•Is the correct city code selected for your Home City?

If you are in Japan, you should have TYO selected for your Home City. For other areas, select the correct Home City code using the procedure under “Selecting Your Home City”.

Auto receive is turned on (ON), but the receive icon “” is not on the display.

•The receive icon appears when a signal is received successfully and the time is updated. It is not displayed if there is no successful signal reception throughout the day. Also note that the icon disappears from the display each day at 3:00 a.m.

Make sure that you are using the watch in an area that is within the reception range of a transmitter, and make sure that the watch is in the Timekeeping Mode or World Time Mode when it is time for auto signal reception.

The current auto receive on (ON)/off (OF) setting does not appear on the setting screen.

•The auto receive on (ON)/off (OF) setting is not displayed unless TYO (Japan), NYC (New York), CHI (Chicago), DEN (Denver), or LAX (Los Angeles) is selected as the Home City.

Use the procedure under “Selecting Your Home City” to select your correct Home City.

The AT, JP40, and JP60 options do not appear for the transmitter selection mode setting.

•The AT, JP40, and JP60 transmitter selection mode options are available only when TYO (Tokyo) is selected as the Home City code.

Use the procedure under “Selecting Your Home City” to select your correct Home City.

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 its 12 o’clock position facing in the general direction of the transmitter.

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 its 12 o’clock position facing in the general direction of the transmitter.

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 D button again. See “To view the last reception date and time” for more information.
