Before installation, check the ground polarity and voltage of the vehicle power. The radio must work with a 13.6
V±15% negative ground electrical system.

Before installation, check how long the screws will extend from the bottom surface of the radio. Drill the mounting
hole cautiously to avoid damage to the vehicle wiring and other parts.

Before you install the radio in the mounting bracket, connect the antenna and power cord to the radio. Use the
dedicated antenna and power cord provided by the Company for digital radios.

Install the radio with the mounting bracket supplied by the Company, to avoid accidental radio looseness. The loose
radio may cause bodily injury.

Install the radio in a location where you can reach the front panel conveniently.

Keep sufficient clearance at the back of the radio for wiring.


of the radio.
