Troubleshooting Guide
What might appear to be a malfunction in your unit may just be the result of slight misoperation or miswiring. Before calling service, first check the following table for possible problems.
No sound. (Blown fuse.)
✔Input (or output) cables are disconnected.
☞Connect the input (or output) cables.
✔Protection circuit may be activated.
☞Check connections by referring to <Protection function>.
✔Volume is too high.
☞Replace the fuse and use lower volume.
✔The speaker cord is shorted.
☞After check the speaker cord and fixing the cause of the short, replace the fuse.
The output level is too small (or too large).

✔The input sensitivity adjusting control is not set to the correct position. ☞ Adjust the control correctly referring to <Controls>.
The sound quality is bad. (The sound is distorted.)
✔The speakers wire are connected with wrong 9 / · polarity.
☞Connect them properly checking the 9 / · of the terminals and wires well.
✔A speaker wire is pinched by a screw in the car body.
☞Connect the speaker wire again so that it is not pinched by anything.
✔The switches may be set improperly.
☞Set switches properly by referring to <Controls>.
1Power indicator
When the power is turned on, the Power indicator lights.
If the Power indicator does not light when the power is turned on, the protection function may be activated. Check whether there is any indication of trouble. Refer to <Protection function> (page 3).

3FILTER switch
This switch allows to apply
•HPF (High-Pass Filter) position:
The filter outputs the band of higher frequencies than the frequency set with the "HPF FREQUENCY" control.
•OFF position:
The entire bandwidth is output without filtering.
•LPF (Low-Pass Filter) position:
The filter outputs the band of lower frequencies than the frequency set with the "LPF FREQUENCY" control.
The speaker output is automatically switched to monaural (L+R).
4BASS BOOST LEVEL control
Sets the low frequency level to be compensated.
5INPUT SENSITIVITY control
Set this control according to the
Use the diagram on the right as a guide.
6LPF FREQUENCY control
Sets the cutoff frequency when the "FILTER" switch is set to "LPF".
7HPF FREQUENCY control
Sets the cutoff frequency when the "FILTER" switch is set to "HPF".
