Amplifier-power supply installation instructions.

f. Amplifier-power supply installation instructions.

To install a

replacement amplifier-power supply onto the AN/GRC-213, proceed as follows

(see Figure 33):

(1) Place the latched receiver-exciter (E) and the amplifier-coupler

(B) on the top of the amplifier-power supply (J).

(2) Slide the latched units toward the rear of the amplifier-power

supply (J) until the receiver-exciter (E) and the amplifier-coupler (B)

fully engage the retaining cleats on the amplifier-power supply (J).

(3) Tighten the fasteners (I) over the hooks located on the front of

the receiver-exciter (E) and the amplifier-coupler (B) until both units are

securely attached to the top of the amplifier-power supply (J).

(4) Connect the audio cable (chained to the front of the amplifier-

power supply) to the lower AUDIO connector (F) on the receiver-exciter (E)

and to the upper AUDIO radio (S) connector on the amplifier-power supply

(J).

(5) Connect the AN/PRC-104(A) power cable to connector J104 (R) on

the rear of the amplifier-power supply (J).

(6) Slide the amplifier-power supply (J) with the latched receiver-

exciter (E) and the amplifier-coupler (B) onto the mounting base (D). The

rear of the amplifier-power supply will be toward the rear of the mounting

base.

Slide the amplifier-power supply straight back until it is fully

seated against the guide pin assembly (Q), located on the mounting base.

(7) Tighten the fasteners (O) over the hooks (P) until the amplifier-

power supply (J) is securely attached to the mounting base (D).

(8) Connect the quick-release ground connector ((C) and (N)), located

on the rear of the amplifier-power supply (J) and the receiver-exciter (B),

to the mounting base (D).

(9) Connect the power cable to connector J101 (K) located on the rear

of the amplifier-power supply (J).

(10) If AN/VIC-1(V) is to be used, connect the intercommunication

cable to connector J102 (L) on the rear of the amplifier-power supply (J).

(11) If the parallel radio set is to be used, connect its power cable

to connector J103 (M) on the rear of the amplifier-power supply (J).

(12) Connect the RF cable to the BNC connector (G) on the amplifier-

coupler (B).
