■ Power Cable Connection
The transceiver operates in 12 V negative ground systems only! Check the battery polarity and
voltage of the vehicle before installing the transceiver.
Check for an existing hole, conveniently located in the firewall, where the power
cable can be passed through.
• If no hole exists, use a circle cutter to drill a hole, then install a rubber grommet.
Run the power cable through the firewall and into the engine compartment.
Connect the red lead to the positive (+) 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.
■ Installing the Transceiver
For passenger safety, install the transceiver securely using the supplied mounting bracket and
screw set, so the transceiver will not break loose in the event of a collision.
Note: Before installing the transceiver, check how far the mounting screws will extend below
the surface. When drilling mounting holes, be careful not to damage vehicle wiring or parts.
Mark the position of the holes in the dash, using the mounting bracket as a
template. Using a 4.2 mm (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 transceiver.
Slide the transceiver into the mounting bracket and secure it using the supplied hexheaded 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.
When replacing the fuse in the DC power cable, be sure to replace it with a fuse of the same
value. Never replace a fuse with one that is rated with a higher value.
