OBJECTIVE
Upon completion of this lesson, you will be able to perform preventive
maintenance checks and services (PMCS) on the AN/GRC-213 radio set.
REFERENCES
This lesson is based on TM 11-5820-923-12 and other material approved for US
Army instruction.

continually subject to change. Therefore, base your examination answers on
material presented in this lesson rather than on individual or unit
experience.
22. INTRODUCTION.
PMCS are done to spot minor deficiencies before they
become major and to keep the equipment in good physical and operational
condition.
23. PREVENTIVE MAINTENANCE.
Organizational-level PMCS for radio
sets
normally are done on a monthly and quarterly basis as scheduled on DD
Form
314 (Preventive Maintenance Schedule and Record).
Your supervisor
will
establish a monthly and quarterly PMCS schedule on DD Form 314 for
each
wheeled vehicle that has a radio set, but this PMCS may be done
more
frequently as directed by your supervisor.
a. Monthly (M) PMCS would be scheduled, for example, on 12 January, 12
February, 12 March, and so on.
Quarterly (Q) PMCS (done every 3 months)
would be scheduled; for example, on 12 January, 12 April, 12 July and so on.
The organizational level checks and services are listed in Table 4.
A
record of any faults found during periodic PMCS and the corrective actions
taken should be kept on DA Form 2404.
A faulty item of equipment that
cannot be repaired at the organizational maintenance level will be sent to
the next higher level of maintenance accompanied by a DA Form 2407.
NOTE:
Complete instructions for the use, completion, and disposition of
maintenance forms and records are in DA Pam 738-750.
b. Organizational-level
PMCS
for
communications-electronic
(C-E)
equipment are done to ensure that your unit radio equipment is in top
operating condition.
A comprehensive PMCS program reduces equipment
downtime and increases your unit operational readiness.
c. Some PMCS are considered to be routine and should be done any time
you see that they need to be done.
For some items of equipment, routine
PMCS are not listed in the PMCS table. Routine PMCS that are listed in the
PMCS table are there because others have reported unusual or significant
problems with a particular item of equipment.
Some routine PMCS would
include the following:
(1) Check and ensure that the vehicle radio set as installed is
complete. TM 11-5820-923-12 identifies all items that comprise the AN/GRC-
213 radio set.
