Note
•The “Transmitter Mode” setting specifies the time calibration signal transmitter mode, or turns auto receive off. See “Transmitters” for more information.
•Auto DST (AUtO) can be selected only while LON, PAR, BER, or ATH is selected as the Home City code. For more information, see “Daylight Saving Time (DST)” below.
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.
The time calibration signals transmitted from Rugby and Mainflingen include both Standard Time and DST data. When the Auto DST setting is turned on, the watch switches between Standard Time and DST (summer time) automatically in accordance with the received time signal.
•The default DST setting is Auto DST (AUtO) whenever you select LON, PAR, BER, or ATH as your Home City code.
•If you experience problems receiving the time calibration signal in your area, it is probably best to switch between Standard Time and Daylight Saving Time (summer
time) manually.
