2. Setting the correct radio channel
A special digital transmission pro-
cess ensures that the radio signals
are picked up without errors. This
process also makes it possible to set
10 different radio channels.
When supplied from the factory, all
RF telephone transmitters direct are
set to channel 0.
It is only necessary to set units to
other channels if you have several
different users operating units in the
same building.
Set the required channel by using a
small screwdriver to turn the channel
selector switch, which is located
towards the top of the battery com-
partment, to the required channel
number.
All transmitters and receivers must
be set to the same channel.
