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
combi I RF transmitters are set to chan-
nel 0.
It is only necessary to set units to other
channels if you have several different
users operating units in the same buil-
ding.
Set the channel you want by adjusting
the channel selector switch on the left-
hand side of the unit to the required
channel number. Use a small screwdri-
ver to adjust this switch.
All transmitters and receivers must be
set to the same channel.
