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 in a bidirectional radio system, the radio
receiver cannot send any message back 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 handheld transmitter; the status
display is illuminated.
Note
Do not press the P button until the receivers are in program-
ming mode. The channel for a radio system is decided during
the programming. If the receivers are not in programming
mode, the channel of the sender changes to the unidirectional
mode. In order to restore the starting condition, press the
STOP and P buttons simultaneously for 6 seconds until the
status display lights.
Status display
A radio signal is indicated by the status display (LED ring around
the STOP button) lighting up. The various colours of the status
display mean:
Status display Meaning
Flashing orange Channel (transmitter) not programmed in any
receiver
Flashing orange
rapidly Channel (transmitter) in bidirectional program-
ming mode. Operation of already programmed
receivers is not possible.
Every 3 seconds in group programming mode
(also without pressing a button)
Orange then green Channel (transmitter) is operating bidirectionally
and receiver has received the signal
Orange then fl ashing
red
Channel (transmitter) is operating bidirectionally
and one of the receivers has not received the
signal
Red then green Channel (transmitter) is operating bidirectionally
and receiver has received the signal, batteries
weak
Red then fl ashing red Channel (transmitter) is operating bidirectionally
and one of the receivers has not received the
signal, batteries weak
Green Channel (transmitter) is operating unidirection-
ally: Transmit signal is being sent
Green with repeat,
then red (unidirec-
tional) Channel (transmitter) is deleted
Alternating orange
and green (or red),
then red (bidirec-
tional) Channel (transmitter) is deleted
Flashing red Batteries weak
The transmitting power or the radio range will be reduced by the
reduction in the performance of the battery. No more functions are
executed and there is no display if the voltage drops below 2 V.
