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
confirmation back to the transmitter.
Unidirectional radio system
A unidirectional radio system transmits radio signals to a radio
receiver. However, the radio receiver cannot send back a reply to
the transmitter, unlike in a bidirectional radio system. It is also not
possible to pass on the radio signal from one radio receiver to
another.
Initial operation
Press a button to switch on the hand-held transmitter and illuminate
the display, status display and operating mode display. The hand-
held transmitter is in automatic mode during initial operation.
NOTE
Select the required language by navigating the menu during initial
operation.
