• Before making connections, turn the car ignition off to avoid short circuits.
• Connect the yellow and red power input leads only after all other leads have been connected.
• Run all ground leads to a common ground point.
• Be sure to in su late any loose unconnected leads with electrical tape for safety.
• The use of optical instruments with this product will increase eye hazard.

Notes on the power supply lead (yellow)

• When connecting this unit in combination with other stereo components, the connected car circuit's rating must be higher than the sum of each component's fuse.
• When no car circuits are rated high enough, connect the unit directly to the battery.

Parts list

• The numbers in the list are keyed to those in the instructions.
• The bracket and the protection collar are attached to the unit before shipping. Before mounting the unit, use the release keys to remove the bracket and the protection collar from the unit. For details, see "Removing the protection collar and the bracket ( )".
