Installation
Connect Power
This transceiver should be connected to a 13.8V DC
power supply. It can not be connected directly to an
AC outlet. Connect the transceiver to a regulated
power supply with the supplied power cable. Do not
replace the DC power cable with a thinner wire. The
supplied cable is rated to meet the power requirements
of the transceiver.
Connect the DC power cable to a DC power supply or
battery. Connect the red wire to the positive terminal
and the black wire to the negative terminal. Then, plug
the power connector into the DC power outlet of the
transceiver.
Note: Make sure to turn off the DC power supply and
transceiver before connecting.
The DC power supply can only be connected to an AC
power outlet after all connections are completed.
Keeping the Transceiver Cool
As with all modern electronics, it is very important
that the transceiver not be allowed to overheat. The
Transceiver has been designed to take advantage of
natural air flow to keep it cool. Thus, to help in
providing enough space for natural air flow, it is very

4
important that you install the transceiver using the
supplied mounting bracket. If the transceiver is
installed without providing for adequate air flow, the
transceiver may overheat. If adequate air flow is not
available, the transceiver will be damaged from
overheating. Do not place books or other equipment
directly on the transceiver. Allow 4In (10cm) of
clearance between the rear of the transceiver and any
other objects.
Install with Bracket
An adjustable angle bracket is supplied with the
transceiver. Please attach the bracket to your desired
installation location. Remove the two mounting
screws from the sides of the transceiver and reinstall
them through the holes in the bracket.
Note: Do not install the transceiver where it might interfere
with the deployment of airbags.
Do not place the transceiver in the front windshield. The heat
of the sun may damage the transceiver.
Connect Accessories
Hand Microphone: The Hand microphone connection
jack is located on the left side of the front panel of the
