Radio Mounting

6.1

Mounting Trunnion

The standard mounting trunnion allows the radio to be mounted to a variety of surfaces. Ensure the

mounting surface is able to adequately support the weight of the radio. Allow sufﬁcient space around

the radio for free air ﬂow for cooling. Ensure that the unit is close enough to the vehicle operator to

permit easy access to operating controls. Although the trunnion can be mounted to a plastic

dashboard, it is recommended that the mounting screws be located so they penetrate the

supporting metal frame of the dashboard.

6.2

DC Power Cable Installation

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 3 meter (10 feet) DC power cable shipped with the radio is long enough for installation in most

vehicles. Begin the power cable installation in the following manner:

Determine a routing plan for the power cable with reference to where the radio is to be

mounted.

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 5 mm Ø inner diameter in the access hole to avoid damage to the cable.

CAUTION:

From inside the vehicle, feed the red and black leads (without lugs attached) through the

access hole and into the engine compartment. (see Figure 1-1).
