Operating Instructions

Clock synchronization

When the clock has been connected, the time display shows:
-- --
:00
The '00' indication flashes every second as soon as the seconds clock
frequency runs synchroniously with the time signal and normal-
GB --- ---
frequency transmitter DCF77 in Mainflingen.
If this is not the case after a few seconds, the signal strength is poor or there are signal-interferences.
You should then reposition the connected aerial, for example in a horizontal position at right angles to the
receiver, further away from the receiver and away from metallic objects or switched-on TV receivers.
To help you, the display is provided with 6 segments below the day and date indication.
Try to obtain a maximum number or these segments being visible.
If the signal strength is sufficient, the '00' indication stops flashing and the seconds are count up to 60. If a
correct time telegram has been received, this will be indicated by the radio tower symbol at the right of
the display.
The clock is now running exactly to the second. Synchronization through DCF77 takes place permanently.
The radio tower symbol is switched off if no synchronization was

possible for more than 1 minute. Nevertheless, the clock continues
running being controlled by the built-in quartz.
MO 19. 7.
Pressing the SNOOZE button a longer time (> 5 seconds)
automatically starts new synchronization.
The unit meets the CEE regulations concerning interference radiation.
This set complies with the safety regulations according to VDE 0860 / BS 415 and thus with the
international safety regulations according to IEC 65.
