Information about
wireless intercoms
Possible interference causes
and how to solve them:
Short Function Test
Plug transmitter and receiver in a multiple-socket (as per drawing) Switch
on both sets. In case both operate perfectly now, the mains may be the
cause of the interference. In this case please address to your next after-sales
service or electrical specialist for installation of interference suppresstons.
Do not return your intercoms to the manufacturers before not being sure
whether the intercoms produce the interfering noises or the frequencies
in the mains.
Interference: More or less heavy rustle or crackle noise influence the
quality of reception.
Cause:
One
connecte.d
electric equipment supplies the interfering
noise.
Remedy:
Unplug all electric equipments. Connect same again, one
by one, till you get the interfering noise again. Now you
discovered the “producer”. An adapter (for domestic
appliances or TV) will solve this problem. Consider,
however, a slight constant background noise during the
transmission is normal as no mains works completely
noiseless.
Interference: You hear heavy noise although all equipments are
unplugged despite the intercoms (eventually reception of
other Intercoms).
Cause:
Interferences from outside enter in your domestic electric
circuit.
Remedy:
A specialist has to install a carrier-frequency filter or has to
alter the phases. In case you operate with multi-way-sets
first try to select another channel (frequency). This might be
already sufficient.
I
Interference:
No communication at all between the various intercoms
Cause:
Both sets operate on different phases
Remedy:
A specialist must install a phase coupler (VIVANCO PK 1) to
bridge the different electric circuits.
