2.The antenna of this watch is located on its 6 o’clock side. Position the watch with 6 o’clock facing towards a window as shown in the nearby illustration. Make sure there are no metal objects nearby.

6 o’clock

••Signal reception normally is better at night.

••The receive operation takes from two to seven minutes, but in some cases 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.

••Signal reception may be difficult or even impossible under the conditions described below.

Inside or among Inside a vehicle	Near household	Near a	Near	Among or behind
buildings	appliances,	construction	high-tension	mountains
	office equipment,	site, airport, or	power lines
	or a mobile	other sources of
	phone	electrical noise

3.What you should do next depends on whether you are using Auto Receive or Manual Receive.

••Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive” for details.

••Manual Receive: Perform the operation under “To perform manual receive”.Auto Receive

••With 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 Home City time). When any receive operation is successful, none of the other receive operations for that day are performed.

••The receive operation is not performed if a calibration time is reached while you are configuring settings.

To perform manual receive

1.In the regular timekeeping mode, keep Adepressed (for about two seconds) as the x Second Hand goes through the following sequence.

••Moves 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 Hand is	It means this:
	pointed here:	It means this:
	pointed here:
	READY (R)	Watch is setting up for reception.
	WORK (W)	Reception is in progress.

	YES (Y)	Reception was completed successfully.
	YES (Y)	Reception was completed successfully.
	NO (N)	Reception failed for some reason.

••If 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 five seconds, and then resumes regular timekeeping.

••You can return to regular timekeeping manually by pressing Awhile the x Second Hand is pointing to YES (Y) or NO (N).

	••When the receive operation is successful, the watch adjusts the time

	setting accordingly. It does not adjust the setting if the operation failed.

Note

••To interrupt a receive operation and return to the regular timekeeping, press any button.

To check the result of the latest receive operationIn the regular timekeeping mode, press A.

	••The 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.

	••You can return to regular timekeeping manually by pressing Awhile the
	x Second Hand is pointing to YES (Y) or NO (N).

Note

••The x Second Hand will indicate NO (N) if you have adjusted the time or date setting manually since the latest receive operation.

Radio-controlled Atomic Timekeeping Precautions••Strong electrostatic charge can result in the wrong time setting.

••Even if a receive operation is successful, certain conditions can cause the time setting to be off by up to one second.

••The watch is designed to update the date 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.

••If you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Specifications”.

••The receive operation is disabled under any of the following conditions. −−While power is at Level 2 or lower

−−When the watch is in the function sleep state (“Power Saving”)

To configure Home City settings

Note

••This watch does not have a city code that corresponds to Newfoundland.1. Press Cto enter the World Time Mode.

	2. Use Dto move the x Second Hand clockwise until it is indicating the city


	code you want to select as the World Time City.

••Each press of Dmoves the x Second Hand to the next city code.

••About 1.5 seconds after you press D, the time setting will change to the current time in the selected city. Note that it may take some time (about one minute) before the watch’s hands stop moving.

••All operations except for the following are disabled while the watch’s hands are moving to the current time for a newly selected city code. D: City selection

C: Entering the Regular Timekeeping Mode••For details about city codes, see the “City Code Table”.

3.Hold down Afor about two seconds to toggle between daylight saving time and standard time.

••Changing the setting will cause the x Second Hand to move to STD or DST.

••The x Second Hand will return to the city code you selected in step 2 after about five seconds, or if you press Aagain.

••If you want to configure other settings, wait until the x Second Hand moves back to the city code before proceeding.

••You can select STD or DST for each World Time City code, except UTC.

4.After the settings are the way you want, hold down Bfor about three seconds until the watch returns to the Regular Timekeeping Mode.

••As you hold down B, the x Second Hand will move to either AM (A) or PM (P), and then the watch will enter the Regular Timekeeping Mode.

Note

••After you specify a city code, the watch will use UTC* offsets to calculate the World Time based on the current time in your Home City.

**Coordinated Universal Time, the world-wide scientific standard of timekeeping. The reference point for UTC is Greenwich, England.

••Selecting some city codes makes it possible for the watch to receive the time calibration signal for the corresponding area automatically. See “Radio Controlled Atomic Timekeeping” for details.
