Explanation of functions
Bidirectional radio system
A bidirectional radio system transmits radio signals to a radio
receiver and enables feedback from the radio receiver to the
transmitter. The radio signal can be sent directly to the target
receiver. If this is not possible then the radio signal is forwarded via
other bidirectional participants until the signal reaches the target
receiver. The target receiver carries out the command and sends a
con
fi
rmation back to the transmitter.
Bidirectional radio operation is only possible if all participants are
bidirectional. Otherwise, the system is only unidirectional.
Unidirectional radio system
A unidirectional radio system transmits radio signals to radio
receivers. However, unlike the bidirectional radio system, the
radio receivers cannot send back a reply to the transmitter. The
transmission of radio signals from radio receiver to radio receiver is
also not possible.
Initial operation
Press a button to switch on the hand-held transmitter and illuminate
the status display and operating mode display. The hand-held
transmitter is in automatic mode during initial operation.
Note
Do not press the
P
button until the receivers are in
programming mode. The active channel for a radio system
is decided during programming. If the receiver is not in
teach-in mode, the channel from the transmitter changes to
unidirectional mode. Press and hold the
STOP
and
P
buttons
simultaneously for 6 seconds until the status display lights up.
