Troubleshooting Guide
The following checklist will assist in the correction of most problems which you may encounter with your unit.
Before going through the checklist below, refer to the connection and operating procedures.
Cause/Solution
The fuse is blown. t Replace the fuse with a new one.
The ground lead is not securely connected. t Fasten the ground lead securely to
a metal point of the car.
The voltage going into the remote terminal is too low.
•
The connected master unit is not turned on.
t
Turn on the master unit.
• The system employs too many amplifiers. t Use a relay.
Check the battery voltage (10.5 – 16 V).
Turn off the power switch. The speaker outputs are short-circuited. t Rectify
the cause of the short-circuit.
Turn off the power switch. Make sure the speaker cord and ground lead are
securely connected.
The unit heats up abnormally.
• Use speakers with suitable impedance.
— 2 – 8 Ω (stereo) , 4 – 8 Ω (when used as a bridging amplifier).
• Make sure to place the unit in a well ventilated location.
The power connecting leads are installed too close to the RCA pin cords. t Keep
the power connecting leads away from the RCA pin cords.
The ground lead is not securely connected. t Fasten the ground lead securely to
a metal point of the car.
Negative speaker leads are touching the car chassis. t Keep the leads away
from the car chassis.
The FILTER switch is set to the “LPF” position.
The level adjustment control is set to the “MIN” position.

Coupez l’interrupteur d’alimentation. Les sorties de haut-parleur sont court-
circuitées. t Remédiez à la cause du court-circuit.
Coupez l’interrupteur d’alimentation. Assurez-vous que le cordon de haut-
parleur et le fil de masse sont correctement branchés.
L’appareil chauffe anormalement.
• Utilisez des haut-parleurs d’une impédance appropriée.
— 2 – 8 Ω (stéréo) , 4 – 8 Ω (
utilisé comme amplificateur en pont).
• Installez l’appareil dans un endroit bien aéré.
Les câbles d’alimentation sont installés trop près des câbles à broches RCA.
t Eloignez les câbles d’alimentation des broches RCA.
