Safety precautions

2WARNING

To prevent injury or fire, take the following precautions:

•When extending the ignition, battery, or ground wires, make sure to use automotive- grade wires or other wires with a 5 mm2 (AWG 10) or more to prevent wire deterioration and damage to the wire coating.

•To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the unit.

•If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer.
