Assembly and Installation
Assembly of the unit consists of installing the receiv-
ers in the frame and connecting the antenna leads and
power cables to each receiver.
“A” Antenna Leads
“B” Antenna Leads
Power Supply Leads
Installing the Receivers
1. Remove the U-channel wire cover by completely re-
moving the four counter-sunk phillips head screws
from the top of the unit. Underneath the U-channel
wire cover is a rectangular metal bar held down
by five counter-sunk phillips head screws. Loosen
these five screws five to seven turns (it’s not neces-
sary to remove them completely.)
Note: Before installing the receivers, be sure to
record the serial numbers and frequencies. This
information is printed on the side panel labels
which won’t be visible after installation.
2. Route the three longest “B” antenna leads behind
the post nearest the housing as shown here. Re-
move the screw from the post next to the housing if
necessary to route the longer “B” leads. The short-
est “B” lead should be routed along the housing
directly to the front panel.

3. Route the antenna leads through the slots on the
front of the frame before mounting the receivers.
Start with the shortest “A” lead and the shortest “B”
lead for the receiver closest to the power supply,
then the next shortest A and B leads for the next re-
ceiver, and so forth. Each diversity receiver must be
connected to an “A” lead and a “B” lead for diversity
reception.

4. Insert the first receiver into the slot nearest to the
power switch by sliding it under the wiring harness
and the rectangular metal bar. Be sure the front
panel of the receiver is fully inserted into the cutout
on the inside of the front panel. Install the remaining
receivers in the same manner.
5. Secure the receivers into the frame by tightening
the five counter-sunk phillips head screws in the
rectangular metal rod. Don’t overtighten!
With each receiver, route the
“B” antenna cable under the
bar and place it in the gap
next to the screw.
