8.2 Antenna Short-Circuit

(Only for assembly groups with front display)

In case of an antenna line short-circuit the following message appears in the display:

ANTENNA

SHORT-CIRCUIT

DISCONNECT POWER

! ! !

If this message appears the clock has to be disconnected from the mains and the defect eliminated. After that
the clock can be powered-up again. The supply voltage for the antenna/converter unit is approx. 15 V DC when
the antenna is connected.
