HOW TO PROCEED IN CASE OF FAULTS
No function
The connection cable is not connected correctly (=terminals +12v/Gnd/rmt).
Ensure that all connections have electric and mechanic contact and that
the jacket has been removed. The fuse is defective - pay attention to the
correct value of a new fuse!
No sound
Speaker cables or speaker plugs are not connected correctly.
No sound / green LED shines
The plus and minus wires of the speaker cables have contact, thus
eliminate the short circuit.
Poor sound quality (distortions)
The speakers are overloaded, therefore turn down the volume level and
check the volume control positions.
INTERFERENCE
All cables are source of interference or gather them. The power cable and
Cinch/RCA audio cable are very prone to interference; the remote cables
are less prone. There is often interference caused by the generator (pi-
ping), ignition (crackling) or other car electonic parts. Most of these pro-
blems can be eliminated by correct and careful cabling. In doing so, there
are the following guidelines:
- Use only a shielded audio cables for the wiring between Òlow level
inÓ of the amplifier and RCA or DIN outputs of the radio.
- Lay the signal, speaker and power cables separately with enough
distance from another and also from any other car cable. If not
possible, you can lay the circuit and ground cable together with the
serial cables. Audio and speaker cable should be as far away from
these as possible. The Rmt cable to the automatic antenna output
of the radio can be laid together with the signal cables
