NB: The TC “Marche” is
not given to the transmitter.
If it was OFF on load, it
will remain OFF, if it was ON,
it will be ON on air after the
permutation.

Validation of the permutation
means: Relay OK & Audio OK

Figure 6-8:Permutation
The first step of this process is to disable the power output of the transmitters
involved in the permutation. This is done giving the OFF TS on both transmitters
and waiting for the relevant TS to have the required values (HT and RF Power
have to disappear).
