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.

x On the dashboard of a car parked in direct sunlight x Too close to an incandescent lamp

x Under direct sunlight

Important!

x 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.

x 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.

Checking the Current Power Level

Certain functions will be disabled when the power level is low. If the power level is low, leave the watch in a location where its face (solar panel) is exposed to light.

To check the current power level

1.In the Timekeeping Mode, press B. The 2 Second Hand will move to H (High), M (Medium), or L (Low) to indicate the power level.

x When power drops to Level 3, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults.

x When the watch is at Level 3, exposing it to light for a while will cause the 2 Second Hand to move to the position of second 57. This indicates that charging has started.

Power Recovery Mode

The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever power suddenly drops below a certain level due to continuous signal reception or other operations over a short period. Note that all operations are disabled while the watch is in the power recovery mode.

The hands will move to the correct positions and the watch will resume normal operation after power recovers (in about 15 minutes). Putting the watch in a location where it is exposed to light will help power to recover sooner.

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 Day Settings Manually” (page E-43) 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.

E-21

	If your Home City Code setting is this:	The watch can receive the signal from
		the transmitter located here:
	LON (LONDON), PAR (PARIS), ATH (ATHENS)	Anthorn (England), Mainflingen

	HKG (HONG KONG)	Shangqiu City (China)
	TYO (TOKYO)	Fukushima (Japan), Fukuoka/Saga
		(Japan)
	HNL (HONOLULU), ANC (ANCHORAGE),
	LAX (LOS ANGELES), DEN (DENVER),	Fort Collins, Colorado (United States)
	CHI (CHICAGO), NYC (NEW YORK)

Important!

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

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

x Auto Receive: Leave the watch over night in the location you selected in step 2. See “Auto Receive” on page E-28 for details.

x Manual Receive: Perform the operation under “To perform manual receive” on page E-29.

Auto Receive

x 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 Timekeeping Mode time). When any receive operation is successful, none of the other receive operations for that day are performed.

x When a calibration time is reached, the watch will perform the receive operation only if it is in the Timekeeping Mode. The receive operation is not performed if a calibration time is reached while you are configuring settings.

To perform manual receive

1.In the Timekeeping Mode (page E-37), keep Bdepressed (for about two seconds) as the 2 Second Hand goes through the following sequence.

x Moves to H (High), M (Medium), or L (Low) to indicate the power level and then moves to R (READY).

2.The 2 Second Hand indicates the operations the watch is currently performing.

			When the 2 Second Hand is	It means this:
			pointed here:
			R (READY)	Watch is setting up for reception.
30			W (WORK)	Reception is in progress.

x If signal reception is unstable, the 2 Second Hand may move between W (WORK) and R (READY).

x When the receive operation is successful, the watch adjusts the time setting accordingly, and then resumes

2regular timekeeping. It does not adjust the setting if the operation failed.
