(c) Two "Take Control" switches (one for each transceiver) allow the operator to switch
the control of a radio between control heads.
(d) The primary headset/microphone audio's on P500 of each C-5000 are paralleled and
connected to the FM1 position on the audio panel. The secondary
headset/microphone audio's on P500 of each C-5000 are paralleled and connected
to FM2 position on the audio panel.
If an operator wants to control RT-5000 #1 with C-5000 #1, they put the Take Control switch for radio
#1 in the position that grounds pin 17 of P501 on C-5000 #2. At this point, C-5000 #2 gives up control
of RT-5000 #1 and displays "NO CONTROL" on the top line of its display. C-5000 #1 will now show the
status of RT-5000 #1 on the top line of its display To transmit on radio #1, the operator tunes
the audio panel to FM1 and pushes the PTT switch.
If an operator wants to control RT-5000 #1 with C-5000 #2, they put the Take Control switch for radio
#1 in the position that grounds pin 17 of P501 on C-5000 #1. At this point, C-5000 #1 gives up control
of RT-5000 #1 and displays "NO CONTROL" on the top line of its display. C-5000 #2 will now show the
status of RT-5000 #1 on the top line of its display To transmit on radio #1, the operator tunes
the audio panel to FMI and pushes the PTT switch.
If an operator wants to control RT-5000 #2 with C-5000 #1, they put the Take Control switch for radio
#2 in the position that grounds pin 17 of P501 on C-5000 #2. At this point, C-5000 #2 gives up control
of RT-5000 #2 and displays "NO CONTROL" on the bottom line of its display. C-5000 #1 will now show
the status of RT-5000 #2 on the bottom line of its display To transmit on radio #2, the operator
tunes the audio panel to FM2 and pushes the PTT switch.
If an operator wants to control RT-5000 #2 with C-5000 #2, they put the Take Control switch for radio
#2 in the position that grounds pin 17 of P501 on C-5000 #1. At this point, C-5000 #1 gives up control
of RT-5000 #2 and displays "NO CONTROL" on the bottom line of its display. C-5000 #2 will now show
the status of RT-5000 #2 on the bottom line of its display To transmit on radio #2, the operator
tunes the audio panel to FM2 and pushes the PTT switch.
All the above boils down to the following: To use RT-5000 #1, put the "Take Control" switch in
the position so the operators control head shows the status of RT-5000 #1. To transmit, put the audio
panel on FM1. Do the same for transceiver #2 except use Take Control switch for RT-5000 #2 and
then select FM2 on the audio panel.
