Before applying 13.8 VDC primary power to radio for the first time, inspect wiring going
to accessory connector very carefully. Ensure that pin 1 (speaker+), and pin 2 (speaker-)
ARE NOT connected to chassis ground. Failure to follow this precaution may result in
permanent damage to the radio and require replacement of audio power amplifier integrated
circuit and/or complete transceiver board.
This radio must be operated only in negative ground electrical systems. Reverse polarity
will cause the cable fuse to blow. Check the vehicle ground polarity before you begin
installation to prevent wasted time and effort.
The DC power cable shipped with the mobile radio is long enough for installation in most
vehicles. Begin the power cable installation in the following manner:
1.
Determine a routing plan for the power cable with reference to where the radio is to
be mounted.
2.
Locate an existing hole with a grommet in the vehicle fire wall, or drill a 10 mm Ø
access hole at the location for passing the power cable into the engine compartment.
Install a grommet with a 5 mm inner diameter in the access hole to avoid damage to
the cable.
High degree of care should be exercised not to damage any existing vehicle wires.
3.
From inside the vehicle, feed the red and black leads (without lugs attached) through
the access hole and into the engine compartment (see Figure 10).

4.
Locate the nearest available vehicle chassis ground mounting point and shorten the
black lead to remove excess cable length.
5.
Install ring lugs (supplied) onto stripped end of power cable black lead, and onto
stripped end of red lead on fuse holder (see Figure 11).
6.
Locate the fuse holder as close to the battery as possible and away from any hot
engine component. Mount the fuse holder using the provided mounting hole and
dress wires as necessary. Connect the fuse holder red adaptor lead plug to the mating
receptacle on the red lead of the power cable (see Figure 11).
7.
Connect the power cable black lead directly to the vehicle chassis ground.
