2-7. Functional Description. The recorder set consists of two major assemblies:

power supply and recorder (figure 2-6). A microphone and/or receiver and head-

set are used during normal operation.

a. Power Supply. Fuse card (2A1) provides overload protection in normal oper-

ation of the recorder set.

b. Recorder. Authorized maintenance at organizational level is limited to fuse

replacement of the power supply, therefore, principles of operation of the recorder

will not appear in this chapter.

c. Operation. A microphone and/or a receiver may be used to apply voice informa-

tion to the recorder set, to be recorded on a cassette tape for future use. To monitor

this recorded or reproduced information a headset is used.

NOTE

Microphone information cannot be monitored during recording.
