Note
Do not press the
P
button until the receivers are in programming
mode. The active channel decides for a radio system during
programming. If the receivers are not in programming mode, the
transmitter channel changes to unidirectional mode. Press the
STOP
and
P
buttons simultaneously for 6 seconds until the status
display lights up, to restore the initial condition.
Status display of the indicator lamp
A radio signal is displayed by the illumination of the status display
(LED indicator lamp). After the status display, the operating mode
of the transmitter is displayed by the same indicator lamp.
Explanation of functions
Bidirectional radio system
A bidirectional radio system transmits radio signals to radio receiv-
ers and enables feedback 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 confirmation back to the
transmitter. Bidirectional radio operation is only possible, if all
participants are bidirectional. Otherwise, the system is only unidi-
rectional.
Unidirectional radio system
A unidirectional radio system transmits radio signals to radio
receivers. However, unlike in a bidirectional radio system, the
radio receivers cannot send back any feedback to the transmitter.
A passing-on of the radio signals from one radio receiver to the
next radio receiver is not possible.
Initial operation
The handheld transmitter is switched on by pressing the button,
and status display and operating mode are displayed successively
by the indicator lamp. The handheld transmitter is in automatic
mode during initial operation. As long as no receiver is pro-
grammed, the automatic display is not available.
