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.
Problem Cause/Solution
The POWER/PROTECTOR
indicator does not light up.
The fuse is blown. —► Replace the fuse with a new one.
The ground lead is not securely connected. —► 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. —♦ Turn on the master unit.
• The system employs too many amplifier. —► Use a relay.
Check the battery voltage (10.5 - 16 V).
The OVER CURRENT indicator light up Turn off the power switch. The speaker outputs are short-circuited. —>
In amber. Rectify the cause of the short-circuit.
The OFFSET indicator lights up in
amber. Turn off the power switch. Make sure the sp>eaker cord and ground lead
are securely connected.
The THERMAL indicator lights up in
amber.
The unit heats up abnormally.
• Use speakers with suitable impedance.
- HI-CURRENT mode: 1 to 8 П.
- HI-VOLTAGE mode: 2 to 8 D.
Use HI-CURRENT mode to reduce generated heat.
• Make sure to place the unit in a well ventilated location.
Alternator noise is heard. The power connecting leads are installed too dose to the RCA pin cords.
—► Keep the leads away from the cords.
The ground lead is not securely connected. —► Fasten the ground lead
securely to a metal point of the car.
Negative speaker leads are touching the car chassis. —» Keep the leads
away from the car chassis.
The sound is muffled. The FILTER selector switch is set to the "LPF" position.
The sound is too low. The LEVEL adjustment control is set to the “MIN" position.
