High-speed Movement	To stop high-speed movement

When rotating the crown to move the hands of the watch, you can use the operations described below to move the hands at high speed, either forward or back. There are two high-speed levels: HS1 and HS2 (faster than HS1).

To start HS1 high-speed movement

While the crown is pulled out, rotate it rapidly three turns away from you (for forward movement) or towards you (for reverse movement). High-speed movement will continue even if you release the crown.

To start HS2 high-speed movement

While HS1 high-speed movement is in progress, again rotate the crown rapidly three turns in the same direction as the current HS1 movement (away from you for forward movement or towards you for reverse movement).

Rotate the crown in the direction that is opposite that of the current high-speed movement or press any button.

Note

x If you do not perform any operation for more than two minutes after pulling out the crown, crown operations will become disabled automatically. If this happens, push the crown back in and then pull it out again to re-enable crown operations.

x You can use high-speed hand movement when configuring time settings in the Timekeeping Mode, Alarm Mode, or Countdown Timer Mode.

x Button operations become disabled after you perform a crown operation. If this happens, rotate the crown slightly. This should restore button operations.

possible.

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.

E-14	E-15

Low Power

Moves at two-second intervals.

E-16

Low power conditions are indicated by the movement of the x Second Hand in the Timekeeping Mode.

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

x 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.

	3	x Second Hand stopped.	All functions disabled

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 x 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 “Confi guring Current Time and Day Settings Manually” (page E-41) 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-20

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

Important!

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

Configuring Home City Settings

The Home City is location where you will normally use the watch. You can choose from a selection of city codes that represent 29 cities around the globe.

To configure Home City settings

Note

x This watch does not have a city code that corresponds

to Newfoundland.

1. Pull out the crown.

x This will cause the x Second Hand to move to the

city code of the currently selected Home City. x This indicates the city code setting mode.

TYO (TOKYO)

x If you do not perform any operation with the crown for about two minutes after pulling it out, crown operations will become disabled and the hand will not move if you rotate the crown. If this happens, push the crown back in and then pull it out again.

x For details about city codes, see the “City Code Table” at the back of this manual.

2. Rotate the crown to move the x Second Hand to the city code you want to select as your Home City.

x Each time you select a city code, the z Hour Hand,

c Minute Hand and n Day Indicator move to the

current time and day for that city code.

3. Push the crown back in to return to the Timekeeping Mode.

E-36	E-37

STD/DST Switching

You can select summer time or standard time independently for each city. The initial default setting for all cities is AT (AUTO).

Normally you should use the AT (AUTO) setting because it automatically switches between summer time and standard time. You should change the setting to STD (standard time) or DST (summer time) in the following cases.

−When using a time of a location that is not included in the watch’s list of 29 cities

−When the preset AUTO standard time/summer time timing is incorrect for some reason

Daylight Saving Time (DST)

Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.

x Note that you cannot switch between STD (standard time) and DST (daylight saving time) while UTC* is selected as your Home City.

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

To switch between standard time and summer time manually

1.Perform steps 1 and 2 under “To confi gure Home City settings” (page E-36). x Selecting a city code will cause the z Hour Hand, c Minute Hand, and

v Upper Dial Hand to move automatically to the current time for the selected city code.

x If you will use the watch in a city that is not included in the city code list, select a city code that is in the same time zone as your city.

x Displaying the Home City Settings screen will cause the b Lower Dial Hand to move to AT (auto switching), STD (standard time), or DST (daylight saving time).

AT (AUTO) The watch automatically switches between standard time and daylight saving time in accordance with its calendar.

STD	The watch always shows standard time.
DST	The watch always shows daylight saving time.
