The preceding diagram shows the recommended modes of
scrambler operation.
In example A. of the diagram, the body transmitter is
operating in the CLEAR (CL) mode. The repeater, which is in
the CLEAR (CL) mode, receives the clear transmitter signal
and re-transmits the signal in the clear mode. The Unitel®
receiver is set to the CLEAR (CL) mode.
In example B. of the diagram, the body transmitter is
operating in the SCRAMBLE (SC) mode. The repeater, which
is in the CLEAR (CL) mode receives the scrambled transmitter
signal and re-transmIts the signal unchanged (scrambled).
The Unitel® receiver is set to the SCRAMBLED (SC) mode.
In example C. of the diagram, the body transmitter is
operating in the CLEAR (CL) mode. The repeater is operating
in the SCRAMBLED (SC) mode. The repeater receives the
CLEAR signal, scrambles it, and re-transmits aSCRAMBLED
signal. The Unitel® receiver is set to the SCRAMBLED (SC)
m o d e .
In Summary:
When the repeater mode switch is in the CL position, the
repeater re-transmits the signal as received. For example. If
the repeater receives aCLEAR signal, it re-transmits a
CLEAR signal, if the repeater receives aSCRAMBLED signal,
it re-transmits aSCRAMBLED signal.
If the repeater is set to SCRAMBLE (SC) mode, and it
receives ascrambled signal, the repeater will re-transmit a
clear signal. This is not arecommended mode of operation.
