When Radio Set AN/VRC-7 is installed in a vehicle, the operating installation is referred to as a system. The radio set proper is refered to as a basic set and it must be combined with an installation unit before an operating system can be effected.
Receiver-Transmitter RT-70/GRC, which is a unit of Radio Set AN/VRC-7, is often referred to simply as the Receiver-transmitter. Because it often is used in conjunction with other receiver-transmitters in more complex systems, Receiver-Transmitter RT-70/GRC is referred to also as Set 2 on control unit panels and some schematic diagrams. In Radio Set AN/VRC-7 there is no Set 1 receiver-transmitter, although panel and schematic references are made to such a set.
AF Amplifier AM-65/GRC, another major unit of the radio set, generally is referred to by the more functional title of interphone amplifier. The various control units of the radio set also are referred to by functional title as follows :
- Local Control C-434/ GRC is referred to as the local control unit.
- Remote Control C-433/ GRC is referred to as the remote control unit.
- Control Box C-375/VRC is referred to as the interphone box or simply as the control box.
The term power supply is used to designate Power Supply PP-281/GRC, Power supply PP-282/GRC, or Power Supply PP-448/ GRC, any one of which may be used to supply operating voltages for both Receiver-Transmitter RT-70/GRC and AF Amplifier AM-65/GRC. The vehicular battery voltage available determines which power supply must be used, Power Supply PP-448/GR, PP-281/GRC, or PP-282/GRC, being required for 6-volt, 12 volt, or 24-volt operation, respectively.
