TRANSMIT WILL RESULT WHEN THE OTHER END OF THE AUDIO CABLE (E) IS CONNECTED
TO EITHER AUDIO CONNECTOR ((G) OR (H)) OF THE RECEIVER-EXCITER. THIS COULD
DAMAGE THE AN/PRC-104(A).
d. Connect the audio cable (E), attached to the front of the amplifier-
power supply by a short chain, to the upper AUDIO RADIO connector (I)
located on the front of the amplifier-power supply. Connect the other end
of the AUDIO cable (E) to lower AUDIO connector (G) on the front of the
e. Connect the RF cable (J) from the BNC connector (K) on the
amplifier-coupler to BNC RADIO-RF connector J201 (L) on the switching unit
f. If a loudspeaker is to be used in the vehicle, connect an LS-454
loudspeaker to the lower AUDIO SPEAKER connector (F) on the amplifier-power
g. Connect an H-250/U handset to the upper AUDIO connector (H) on the
front of the receiver-exciter.
(The handset, or a second handset, may be
connected to the lower AUDIO SPEAKER connector (F) on the front of the
amplifier-power supply if the loudspeaker is not use.)
h. If the
(1) Connect the intercommunication cable (part of the installation
kit) to connector J102 (M) on the rear of the amplifier-power supply.
Verify that the other end of the intercommunication cable is connected to
the audio frequency amplifier (part of AN/VIC-1(V)) as described in the
(2) If the AN/VIC-1(V) is to be used for the retransmit capability,
connect the vehicular VHF FM radio power cable to connector J103 (N) on the
rear of the amplifier-power supply.
i. If a parallel radio set is to be used, connect its power cable to
connector J103 (N) on the rear of the amplifier-power supply.
j. If the dipole antenna is to be used in place of the whip antenna
(refer to paragraphs 4b(2)(a) and (b) for antenna comparison), connect the
dipole RF cable to the dipole antenna adapter. Connect the dipole RF cable
with adapter to connector J203 (O) on the rear of the switching unit (part
GROUNDING REQUIREMENTS. For
proper operation, the AN/GRC-213 must be
properly grounded. Jumper cables
with quick-release connectors (Figure 19
(P)) are provided on the rear
of both the receiver-exciter and the
the grounding jumpers to the jumpers
attached to the upper tray of the
