wires/leads and the vehicle body. Collect all wires as bundles and make sure that the ends of the
wires do not have any contact with metal parts.
NOTES:
• Do not short circuit the antenna and ground wire.
• This unit has a negative grounding.
• Do not short circuit the speaker wires.

Precautions
• Must use only not grounded speakers.
• The speakers used with this unit should have a sufficient music power rating.
• Speakers with too low power rating can be damaged.
• Must use 4 - 8 Ω impedance speakers. A too high or to low impedance leads to performance
losses and can damage of the speakers or this unit.
• Don't use a 3 leads speaker system with a common ground wire. Never connect the speaker
wire at the car body.
• Keep the speaker wires away from the antenna and antenna wire (about 30 cm).
• The unit becomes damaged, if speakers (front, rear) are not correctly connected.
• Never connect more than one speaker to a set of speaker wires (except the connection of a
tweeter).
Fuse
As a replacement for a blown fuse it is absolutely necessary to use a fuse with the prescribed rating
(3 A). By the use of fuses with higher ratings or by the connection without the use of a fuse a fire or
a damage of the unit can be caused. If the exchanged fuse is blown likewise, please contact the
next workshop.
