Trotzdem luft die Uhr weiter und wird unterdessen von der Frequenz der Stromversorgung 50 Hz kontrolliert. Drcken Sie die Taste SNOOZE lnger ( 5 Sekunden), startet die Ne

15、usynchronisation. Dieses Gert ist funkenstrt entsprechend den geltenden EG-Richtlinien. Dem Bundesamt fr Zulassungen in der Telekommunikation (BZT) wurde angezeigt, da das Gert in Ver- kehr gebracht wurde.

Interrupting and repeating the wake-up function A short pressure on the SNOOZE button on the top of the set interrupts each wake-

30、up mode and the sleep symbolflashes. After 10 minutes, the wake-up function is recovered. This function can be repeated (within the switch-on period of 60 minutes). In the wake-up mode with radio programme and sound signal, the first brief pressure on the SNOOZE button will interrupt only the sound

31、signal, and the second pressure also the radio. Aborting the wake-up function Keep the SNOOZE button on the top of the set pressed until the symboldisappears. Wake-up standby for the next day is retained. If you do not wish to be woken up at certain days, for example during the weekend, repeatedly p

32、ress the AL. MODE button until no wake-up symbol is indicated. The set wake-up time is retained for the next wake-up procedure. To recover wake-up standby for the next day, select the respective symbol with the AL. MODE button. Wake-up during a mains failure If a mains failure occurs, the wake-up fu

33、nction will not be carried out. When the mains failure is cleared, the clock will first be synchronized. If the mains supply is recovered within 2 hours after the set wake-up time, the selected wake-up function will be made up. If the mains failure lasts longer than 2 hours, the wake-up function for

34、 this day is lost. Mains failure during a wake-up function If the mains supply is recovered within 2 hours after the wake-up function has started, the wake-up functionwill be started again if it was not yet running longer than 3 minutes when the mains failure occured If the wake-up function was alre

35、ady running more than 3 minutes when the mains failure occured, it will not be started again. Going to sleep while listening to the radio You can programme your set so that it automatically switches off after a preset playing time of max. 59 minutes has elapsed. If you wish wake-up standby for the n

The unit will switch on with the last selected radio station and the display indicates thesymbol and a playing time of 10 minutes. By holding the SLEEP button pressed down, this playing time can be increased i

Operating Instructions Setting the time zone The time signal transmitter DCF 77 transmits the time valid in middle-europe, or the Daylight Saving Time of middle-europe. When using your SONOCLOCK 910 in another time zone or to indicate a local time in anot

39、her time zone, you can set the respective time difference as follows: Press and hold first the SNOOZE button and press then also the SLEEP button longer as 5 seconds. The date indication disappears and e.g. the indication TI -4 appears in the bottom part of the display. The indication TI indicates T

40、ime Zone and the figure indicates the time difference in hours between the displayed time and the time received from DCF 77 (middle-europe). For normal use in middle-europa (and after putting the set in operation for the first time) the time difference is installed at 0: After entering the time zone adjustment mode, you can now install the time zone (from -9 to +9 hours) with the +/- buttons. The actual time indicated in the upper part of the display changes respectively and in
