•If you are in an area where signal reception is not possible, the watch keeps time with the precision noted in “Specifications” (page E-79).

•The receive operation is disabled under any of the following conditions.

−While power is at Level 2 or lower (page E-17)

•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 when you rotate the crown. If this happens, push the crown back in and then pull it out again.

•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.

• 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.

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.

•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 scientifi c standard of timekeeping. The reference point for UTC is Greenwich, England.
