Using the Set 840-TV system
What if you don’t hear the desired sound source?
The channel search has possibly found another sound
source (e.g. from another nearby system).
If you still cannot find your sound source:
̈ Change the transmission channel as described in the
next chapter.
̈ Read the chapter “If a problem occurs ...” on page 24.

very close to one another, reception can be subject to inter-

̈ Press the channel search button 4 on the receiver to re-
start the channel search.
If reception is still subject to interference :
̈ Read the chapter “If a problem occurs ...” on page 24.
To continue the channel search:
̈ Press the channel search
button 4 on the receiver
repeatedly until you have
found your sound source.
̈ Change, if necessary several
times, the position of the
channel selector switch F on
the transmitter to change to
an interference-free channel.
