Installation and Preparation for Use

INSTALLATION AND PREPARATION FOR USE.

The following instructions

refer to installing the AN/GRC-213 radio set after you have verified the

proper installation kit on the vehicle. Proper polarity of the power cable

from the battery to the AM-7152/GRC-213 and secure connection of grounds are

critical.

a. Unpacking. The following subparagraphs have unpacking instructions

for the AN/GRC-213.

(1) AN/PRC-104(A). (See Figure 11.) The AN/PRC-104(A) is contained,

transported, and stored in a transit case. The transit case normally should

be kept closed.

To unpack the equipment, unfasten the four latches and

remove the transit case cover. Each of the individual pieces of equipment

fits in a molded space in the case. Check to ensure that the equipment is

complete by referring to the equipment supply list in TM 11-5820-919-12.

Inspect the equipment for any damage incurred during shipment.

The

receiver-exciter, amplifier-coupler, continuous wave (cw) key, and handset

are the components normally used for the AN/GRC-213.

Other equipment

supplied in the transit case is for manpack operation (TM 11-5820-919-12)

and should be stored in the transit case. AN/PRC-104(A) maintenance will be

discussed with its configuration later in the lesson.

(2) Amplifier-power supply and auxiliary equipment.

The amplifier-

power supply and auxiliary equipment for the AN/GRC-213 are shipped in

standard packages sufficient to provide adequate protection from shock and

freight damage.

Verify that all items listed on the packing lists are

present. Inspect the equipment for any damage incurred during shipment.
