BridgeComSystems BCM-220, User Manual

Page: 6 / 32

Unpacking and Radio Preparation:
Electronic equipment (e.g. electronic fuel injection, anti-skid braking, and cruise
control) in your vehicle may malfunction if not properly protected from the RF energy
generated when the BCM-220 is transmitting. Enlist the aid of a knowledgeable Ham or
vehicle mechanic in determining if the equipment will perform normally while
transmitting.
Vehicle Power Cable Connection:
The BCM-220 operates on 12V negative ground systems only! Check the battery polarity
and voltage of vehicle before installing the transceiver. Decide whether to power the radio
from the vehicle “HOT” wire line or the ignition key enabled ACC or ON wire.
Check for an existing hole that is conveniently located in the firewall. This will allow for the
power cable to easily pass through.
If no hole exists, use a circle cutter to drill a hole, then install a rubber grommet.
Run the power cable though the firewall and into the engine compartment.
Connect the red lead to the (+) battery terminal and the black lead to the negative (-)
battery terminal.
Place the fuse as close to the battery as possible.
Coil the surplus cable and secure it with a retaining band.
Be sure to leave enough slack in the cables so the transceiver can be removed for servicing
while keeping the power applied.
Install procedure for inside the vehicle:
For passenger safety, install the BCM-220 securely using the supplied mounting bracket
and screw set. This will ensure the radio will not break loose in the event of a collision.
Mark the position of the hole in the dash, using the mounting bracket as a template.
Using a 4.2mm (5/32 inch) drill bit, drill the holes, then attach the mounting bracket using
the supplied screws. Mount the transceiver within easy reach of the user and where there is
sufficient space at the rear of the transceiver for cable connections.
Connect the antenna and the supplied power cable to the radio.
Slide the transceiver into the mounting bracket and secure it using the supplied hex-headed
screws.
Mount the microphone hanger in a location where it will be within easy reach of the user.
The microphone and microphone cable should be mounted in a place where they will not
interfere with the safe operation of the vehicle.
