Installation / Setup
The installation/setup highlights for the radio include planning the installation by inspecting the vehicle for mounting the radio antenna and accessories, ensuring cable runs are protected, and preventing overheating. The antenna should ideally be mounted in the center of a large, flat conductive area, such as the roof center, with the trunk lid as a preferred alternative. The radio can be mounted using a universal mount bracket, ensuring the surface can support the radio’s weight and allowing space for air cooling. The radio should be positioned for easy access to controls. For DC power, the radio should be installed in negative ground electrical systems only, with the positive power lead connected directly to the vehicle battery positive terminal, and the ground lead to the battery negative terminal. If the DC power is controlled by the vehicle ignition switch, a switching relay should be used. The provided cable is sufficient for the radio’s maximum current demand, but if extended, the additional wire must handle the current and length.
