(8) Slide the latched receiver-exciter (E) and the amplifier-coupler
(B) units forward to disengage the retaining cleats, and lift them from the
amplifier-power supply (J).
(9) Lay the latched receiver-exciter (E) and the amplifier-coupler
(B) on a flat surface, and unfasten the front and rear latches
(respectively),
securing
the
receiver-exciter
and
amplifier-coupler
together.
(10) Carefully separate the receiver-exciter (E) from the amplifier-
coupler (B).
d. Amplifier-coupler
installation
instructions.
To
install
a
replacement amplifier-coupler onto the AN/GRC-213, proceed as follows (see
Figure 33):
(1) Secure the amplifier-coupler (B) to the receiver-exciter (E), and
fasten the latches.
(2) Place the latched receiver-exciter (E) and the amplifier-coupler
(B) on the top of the amplifier-power supply (J).
(3) 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.
(4) 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).
(5) Connect the audio cable to the lower AUDIO connector (F) on the
receiver-exciter (E).
(6) Connect the handset or the telegraph key to the upper audio
connector (H) on the receiver-exciter (E).
(7) Connect the RF cable to the BNC connector (G) on the amplifier-
coupler (B).
(8) Connect the quick-release ground connector (C)
between
the
mounting base (D) and the rear of the receiver-exciter (E).
(9) Connect the AN/PRC-104(A) power cable to the AN/PRC-104(A) power
input connector (A) on the rear of the amplifier-coupler (B).
e. Amplifier-power supply removal instructions.
To remove the
amplifier-power supply from the AN/GRC-213, proceed as follows (see Figure
33):
(1) Verify that the POWER ON/OFF switch on the amplifier-power
supply is set to OFF. If necessary, set the switch to OFF.
(2) Disconnect the
RF
cable
from
the
BNC
connector
(G)
on
the
amplifier-coupler (B).
