Perform the following if it has not been previously done:
1. For all models except A3, remove the control head from its mounting
trunnion. Plug the radio's control cable into the proper location on the
back of the control head. (See Figures 10 and 12.) The connectors
"click" when snapped into place. A4, A5, and A7 control head models
can have the microphone plugged into either the lower left corner of the
control head front panel or in the middle section of the connector on the
rear of the control head. A9 control head models have only the rear
connection on the control head available. Connect the microphone
cable S-hook into the hole in the cable strain relief bracket on the back
of the control head (A9 model) or on the mounting trunnion (A4, A5, and
A7 models).
2. Connect the plug from the speaker lead to the mating connector
coming out of the control cable connector or accessory cable harness
(A3 model).
3. Plug the VIP connector into the remaining location on the back of the
control head.
4. Connect the control cable to the radio and tighten the connector by
tightening the jack screws.
To ensure a proper water seal, the jackscrews on the radio cable
!
connector must be tight. If the accessory port on a remote-mounted
radio is not used, the cover gasket assembly (HLN6233_) must be
installed and torqued to 6 to 8 inch-pounds.

5. Be sure the control head and microphone PTT switches are OFF.
Install the fuse (15-amp for low/mid power and 40-amp for high power)
in the radio power cable fuseholder and the 3-amp fuse(s) in the
ignition cable fuseholder(s).
6. Turn the radio ON at the control head and verify proper operation of all
controls and indicators. Radio operation in some installations require
turning on the ignition. Perform a complete operational check of the
radio.
7. Dress the control and power cables out of the way to prevent damage
(pull any excess cable into the trunk area) securing with clamps and
tie wraps where necessary.
