Cautions
• This unit is designed for negative earth 12 V
DC operation only.
• Do not get the wires under a screw, or caught
in moving parts (e.g. seat railing).
• 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 earth wires to a common earth
point.
• Be sure to insulate any loose unconnected
wires with electrical tape for safety.
Notes on the power supply cord (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.

• Use only the supplied mounting hardware for
a safe and secure installation.
To open/close the front panel smoothly, to insert/
eject a disc easily, and especially to drive safely, a
certain distance between the front panel and the
shift lever is necessary. The necessary distance
differs, depending on the shift lever position of
your car. Before installing the unit, choose the
installation location carefully so that you can
drive safely.
