i. In Manual (Local) Mode, the Switch Controller does not monitor the PA

4. Both TXA and TXB Off at the same time: The Switch Controller will not allow both

PAs to be off (or on) at the same time. If this is desired for test purposes, then it can be

accomplished by an onsite engineer by disabling the PA-to-Switch Controller

communications and simply using the PA front panel On/Off buttons for individual PA

control. Simply follow the steps below.

a. Local (onsite): To turn both TXs off (or on) at the same time ...

i. Put both PAs into Local mode by selecting Local on the PA web

The Switch Controller will still command one of the two PAs on, but

without drive from the exciter, there will be no output power from either

PA. Be sure to remotely network to both PAs, both Exciters, and the

Switch Controller to have full remote control of the system.
