Installation

Notes On Installation

The unit is designed for 12V DC negative ground operation system only. Before installing the unit, make sure your vehicle is connected to a DC12V negative ground electrical system.

The negative battery terminal must be disconnected before making connections, which can decrease the chance of damaging the unit due to short circuit.

Be sure to connect the color-coded leads correctly according to the diagram. Incorrect connection may cause unit malfunction or damage the vehicle electrical system.

Be sure to connect the speaker (-) leads to the speaker (-) terminal. Do not connect the left and right channel speaker cables to each other or to the vehicle body.

Do not block vent or radiator panels. Blocking them will cause heat build-up inside and may result in fire.

After the completion of the installation and before beginning to play the unit (including replacing the battery), please press the RESET button on the front panel with a pointed object (such as a ball-point pen) to set the unit to its initial status.
