	“Charging the Watch”.

2. Check the Home City and the daylight saving time (DST) setting.

Use the procedure under “To configure Home City settings” to configure your Home City and daylight saving time settings.

Important!

Proper time calibration signal reception and World Time settings depend on correct Home City, Home Time, and Home Date settings. Make sure you configure these settings correctly.

3. Set the current time.

••To set the time using a time calibration signal

See “To get ready for a receive operation”.

••To set the time manually

See “Configuring Current Time and Date Settings Manually”.

The watch is now ready for use.

••For details about the watch’s radio controlled timekeeping feature, see “Radio Controlled Atomic Timekeeping”.

Charging the Watch

The face of the watch is a solar cell that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Warning!

Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

••On the dashboard of a car parked in direct sunlight

••Too close to an incandescent lamp

••Under direct sunlight

Important!

••Keep the watch in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.

••Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to bright light whenever possible.

Power Levels

Moves at two-second intervals.

You can get an idea of the watch’s power level by observing the movement of the x Second Hand.

••If the x Second Hand is moving normally at one-second intervals, power is at Level 1.

••If the x Second Hand is moving at two-second intervals, power is at Level 2, which is quite low. Expose the watch to light as soon as possible so it can charge.

••When power drops to Level 3, all functions will be disabled but the watch will continue to keep time internally for about one week. If you recharge the battery sufficiently during this period, the analog hands will move automatically to the correct setting and regular timekeeping will resume. After one week, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults.

••The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep state when 6:00 AM arrives, however, it will remain in the sleep state.

To recover from the sleep state

Move the watch to a well-lit area or press any button.

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Configuring Current Time and Date Settings Manually” for more information.

This section explains how the watch updates its time settings when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.

	If your Home City Code setting is this:	The watch can receive the signal from
		the transmitter located here:
	LONDON (LON), PARIS (PAR), ATHENS (ATH)	Anthorn (England), Mainflingen (Germany)
	HONG KONG (HKG)	Shangqiu City (China)
	TOKYO (TYO)	Fukushima (Japan), Fukuoka/Saga (Japan)
	HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX),	Fort Collins, Colorado (United States)
	DENVER (DEN), CHICAGO (CHI), NEW YORK (NYC)

Important!

••The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration signal transmitters, so certain conditions may cause reception problems.

••When HONOLULU (HNL) or HONG KONG (HKG) is selected as the Home City, only the time and date are adjusted according to the time calibration signal. You need to switch manually between standard time and daylight saving time (DST) if required. See “To toggle the Home City time between standard time and daylight saving time” for information about how to do this.

••Even when the watch is within range of a transmitter, signal reception may be impossible due to the effects of geographic contours, structures, weather, the time of year, the time of day, radio interference, etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the influence of the above conditions becomes even greater.

••Signal 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.

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:
	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.

••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 operation

In 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 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.

••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”)
