ξSignal reception may not be possible at the distances noted below during certain times of the year or day. Radio interference may also cause problems with reception.
−Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
−Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
−Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
−Shangqiu (China) transmitter: 500 kilometers (310 miles)
ξAs of December 2010, China does not use Daylight Saving Time (DST). If China does go to the Daylight Saving Time system in the future, some functions of this watch may no longer operate correctly.
ξUsing this watch in a country covered by a time calibration that is different from the countries it supports may result in incorrect time indication due to local application of summer time, etc.
1.Confi rm that the watch is in the Timekeeping Mode. If it isn’t, hold down Cat least two seconds to enter the Timekeeping Mode.
2.The antenna of this watch is located on its 12 o’clock side. Position the watch with 12 o’clock facing towards a window as shown in the nearby illustration. Make sure there are no metal objects nearby.
ξSignal reception normally is better at night.
12 o’clock | ξ The receive operation takes from two | |
to seven minutes, but in some cases | ||
| ||
or | it can take as long as 14 minutes. | |
Take care that you do not perform | ||
| ||
| any button operation or move the | |
| watch during this time. |
ξSignal reception may be difficult or even impossible under the conditions described below.

3.What you should do next depends on whether you are using Auto Receive or Manual Receive.
ξAuto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive” on page
ξManual Receive: Perform the operation under “To perform manual receive” on page
ξWith Auto Receive, the watch performs the receive operation each day automatically up to six times (up to five times for the Chinese calibration signal) between the hours of midnight and 5 a.m. (according to the Timekeeping Mode time). When any receive operation is successful, none of the other receive operations for that day are performed.
ξWhen a calibration time is reached, the watch will perform the receive operation only if it is in the Timekeeping Mode or World Time Mode. The receive operation is not performed if a calibration time is reached while you are configuring settings.
1.In the Timekeeping Mode, keep Adepressed (for about two seconds) as the x Second Hand goes through the following sequence.
ξMoves to YES (or Y for some models) or NO (N) to indicate the last signal reception result, then to READY (R).
2.The x Second Hand indicates the operations the watch is currently performing.
| When the x Second | It means this: | |
| Hand is pointed here: | ||
|
| ||
| READY (R) | Watch is setting up for reception. | |
| WORK (W) | Reception is in progress. | |
YES (Y) | Reception was completed | ||
successfully. | |||
|
| ||
| NO (N) | Reception failed for some reason. |
ξIf signal reception is unstable, the x Second Hand may move between WORK (W) and READY (R).
3.The receive operation is complete when the x Second Hand moves to YES (Y) or NO (N) for about fi ve seconds, and then resumes regular timekeeping.
ξYou can return to the Timekeeping Mode manually by pressing Awhile the x Second Hand is pointing to YES (Y) or NO (N).
ξWhen the receive operation is successful, the watch adjusts the time setting accordingly. It does not adjust the setting if the operation failed.
NoteξTo interrupt a receive operation and return to the Timekeeping Mode, press any button.
To check the result of the latest receive operation In the Timekeeping Mode, press A.
ξThe x Second Hand will move to YES (Y) for five seconds if the latest receive operation was successful, or NO (N) if it was not. After that, regular timekeeping will resume.
ξYou can return to the Timekeeping Mode manually by pressing Awhile the x Second Hand is pointing to YES (Y) or NO (N).
Note
ξThe x Second Hand will indicate NO (N) if you have adjusted the time or date setting manually since the latest receive operation.

ξStrong electrostatic charge can result in the wrong time setting.
ξEven if a receive operation is successful, certain conditions can cause the time setting to be off by up to one second.
ξThe watch is designed to update the date and day of the week automatically for the period January 1, 2000 to December 31, 2099. Updating of the date by signal reception will no longer be performed starting from January 1, 2100.
ξIf you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Specifications” (page
ξThe receive operation is disabled under any of the following conditions.
−While power is at Level 2 or lower (page
−While the watch is in the power recovery mode (page
−When the watch is in the function sleep state (“Power Saving”, page
ξA receive operation is cancelled if an alarm sounds while it is being performed.
