Caution
• This unit is designed for negative ground 12 V DC operation only.
• Be careful not to pinch any wires between a screw and the body of the car or this unit or between any
moving parts such as the seat railing, etc.
• Before making connections, disconnect the ground terminal of the car battery to avoid short circuits.
• Connect the yellow and red power input leads only after all other leads have been connected.
• Be sure to connect the red power input lead to the positive 12 V power terminal which is energized
when the ignition key is in the accessory position.
• Run all ground wires to a common ground point.
• Connect the yellow cord to a free car circuit rated higher than the unit's fuse rating. If you connect this
unit in series with other stereo comportents, the car circuit they are connected to must be rated higher
than the sum of the individual component's fuse rating. If there are no car circuits rated as high as the
unit's fuse rating, connect the unit directly to the battery. If no car circuits are available for connecting
this unit, connect the unit to a car circuit rated higher than the unit's fuse rating in such a way that if the
unit blows its fuse, no other circuits will be cut off.
• When installing a car without ACC (accessory) position on the ignition key switch, connect the red
power input lead to the + 12 V power terminal which is energized at all times with the yellow lead.
