b. DC-to-DC Converter. The output of the transient suppressor is fed into the dc-to-dc converter. It
provides the following regulated output voltage:

13-3. TWO-WIRE TRANSIENT PROTECTION CIRCUIT.
The two-wire transient protection circuit provides for transient protection of the remote control signals between
the RT and either the control-monitor or the remote control unit.
13-4. POWER SUPPLY ADAPTER CHASSIS.
The power supply adapter chassis provides the basic radio interconnections as shown in figure FO-28. Several
other functions are also performed. The power input is switched on and off by CB1. EMP protection is provided
by CR1 through CR3 and the CCA-diode. The two-wire transient protection circuit couples the RT and either the
control-monitor or the remote control unit.
