BACKUP ASSIGNMENTS, PRIORITIES
This subscreen allows the user to program the RCS20 with priorities for each prime channel. A 1
indicates the highest priority channel and a 9 indicates the lowest priority channel. The highest priority
prime channel for each backup channel will have its modulator and/or demodulator placed in hot standby.
For revertive backup mode, the highest priority channel modulators and demodulators will be backed up if
multiple channels fail.
