j. Attach cables to J2 and J5 of AM-6545.
k. Attach CU-2064 to the shelf, and tighten the wing-nut clamps.
1. Attach cable from J1 AM-6545 to J2 CU-2064, and attach J4 of AM-6545 to J1
of CU-2064 with W5 cable.
m. Attach radio cable from J2 of AM-6879 to J2 of RT-1209.
n. Mount the antenna bracket on the vehicle.
o. Mount the antenna base and antenna.
p. Feed the antenna cable through the polyvinyl chloride (PVC) tubing (part
of the installation kit), clamp it to the vehicle, and attach it to the antenna
base and J4 of the CU-2064.
q. Make certain all radio switches are in the off position, and connect the
power cable assembly to J3 AM-6545. Then connect the other end to the power supply
junction box, red lead to positive and black lead to negative.
WHEN MAKING CONNECTIONS TO THE BATTERY TERMINALS OF A VEHICLE OR TO A POWER SUPPLY,
MAKE SURE CONNECTIONS ARE TIGHT. AVOID ACCIDENTAL GROUNDING OF POSITIVE TERMINALS.
r. Route the power cable out of the way, clamp it in place with the clamps
provided in the installation kit, and add the audio attachments (handset on J1 RT-
s. Make sure polarity is correct.
Pin B of CX-4720 at P3 should be positive.
4. INSTALLATION OR REINSTALLATION. The procedure for mounting equipment when an
installation kit is already installed is the same as in d through m above. The CU-
2064 must be removed from the standard mount and attached to the MT-6378/GRC-193A
tactical antenna siting kit (up to 200 feet from the radio) using the RC-435/U
When used in the remote antenna configuration, the AM-6545
should be operated in the 400-watt position.
The CU-2064 must be effectively
If the remote cable is ran overhead, the weight of the cable must be
supported to prevent damage to the cable connectors. The cable is not designed to
support its own weight. Excess cable on the reel must not be stored with the flat
side toward the radio but stored edge-on to the radio to prevent it acting as a big
