Operation Guide 5285 (OC)

STD/DST Switching

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

Normally you should use the 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 the watch in a city not included in the City Code Table

−When the switching dates in your location are different from those shown in the City Code Table

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.

ξNote 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 ÒTo conÞ gure Home City settingsÓ (page E-22).

ξDisplaying the Home City Settings screen will cause the , Lower Dial Hand to

move to AUTO (auto switching), STD (standard time), or DST (daylight saving time).
