Problem Cause Remedy
Power cannot be
turned on (illumina-
tion does not light).
• The fuse is blown. • Check the (+)/(-) polarity of the power cord and
that the cords are not shorted, then replace
with a fuse with the rated capacity.
• Re-connect the cords correctly by referring to
the connection example (on page 4, 5).
• The power supply pin (yellow) of the 10-pin con-
nection cord is not connected.
• Connect the cord correctly by referring to the
connection example (on page 4, 5).
• Attach the grounding terminal to the metallic
section of the vehicle (not a coated surface) by
tightly screwing it.
• Insert the connector all the way in.
• Check the connections of all cords, then con-
nect the (-) cable to the battery.
• The power control pin (blue/white) of the 10-pin
connection cord is not connected.
• The grounding pin (black) of the 10-pin connec-
tion cord is not connected.
• The 10-pin connector is not plugged in complete-
ly.
• The negative (-) cable of the car battery is discon-
nected.
• Check the connections of all cords, then con-
nect the (-) cable to the battery.
No sound
• The attenuator of the center unit is set to ON. • Switch the attenuator OFF.
• The VOLUME control is set to the MIN position. • Increase the volume to an optimum level (on
page 7).
• The speaker cords are connected improperly. • Connect the cords correctly by referring to the
connection example (on page 4).
• Connection terminals are connected improperly. • Insert the connectors or jacks all the way in to
the terminals.
Sound is small.
• The input level is set to low. • Turn the VOLUME control knob and set the in-
put level to an optimum level.
• Connection terminals are connected improperly. • Plug the cord into the REMOTE terminal.
• Check that the RCA cord is connected properly.
Sound quality is bad
(sound is distorted). • The input level is set to high. • Turn the VOLUME control knob and set the in-
put level to an optimum level.
Sound is unnatural.
• The speaker cords are connected with incorrect
positive (+)/negative (-) polarity.
• Connect the cords correctly by referring to the
connection example (on page 4, 5).
• Attach the grounding terminal to the metallic
section of the vehicle (not a coated surface) by
tightly screwing it.
• The grounding pin (black) of the 10-pin connec-
tion cord is poorly contacted.
Remote control does
not work. • The remote control cord is unplugged. • Plug the cord into the REMOTE terminal.
• Insert the connector all the way in.
The illuminations on
