Chapter 2 Standard Configurations
2.1 Planning the Installation
The XPR 4300/4350/4500/4550 radio operates only in negative ground electrical systems. Before
starting the radio installation, make sure that the ground polarity of the vehicle is correct. Accidentally
reversing the polarity will not damage the radio, but will cause the cable fuses to blow.
Planning is the key to fast, easy radio installation. Before starting the installation, inspect the vehicle
and determine how and where you intend to mount the antenna, radio, and accessories. Plan wire
and cable runs to provide maximum protection from inching, crushing, and overheating.
2.1.1 Installation Examples
Your mobile two-way radio offers various methods of installation, including dash or remote mount.
Except for 110W radios, all versions of the XPR 4300/4350/4500/4550 can be either dash or remote
mounted (see Figure 2-1 through Figure 2-2).
CAUTION Before installing any electrical equipment, check the vehicle manufacturer’s user manual.
