No transformers, relays, contactors or the like are allowed to be
installed within a radius of 1 m around the radio receiver. If
there is a fluorescent lamp in this vicinity, it is necessary to
guarantee that it will be turned off from time to time, in order
ensure that a correct reception is possible during the switching
-
off time.
The transmitter is located in the vicinity of Frankfurt/Main. The
most favourable reception possibility is provided if the printed
front surface of the receiver is facing towards Frankfurt/Main. If
the LED that can be seen through the underside of the radio
receiver is flashing every second, this means the reception is
correct.
If wall mounting is used, the wall should not have any electrical
cables and metallic objects that disrupt reception.
The radio receiver is not allowed to be installed in a switch
cabinet or in the immediate vicinity of one.
After the radio receiver has been connected to a time switch, it
may take up to 60 seconds for the LED on the underside of the
