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 re-
place 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
connection 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 com-
pletely.
• The negative
⊖
cable of the car battery is dis-
connected.
• Check the connections of all cords, then con-
nect the
⊖
cable to the battery.
No sound
• The attenuator of the audio components 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 improper-
ly.
• 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
input level to an optimum level.
• Connection terminals are connected improper-
ly.
• Plug the cord into the REMOTE terminal.
• Check that the RCA cord is connected proper-
ly.
• Large power input causes the protection circuit
for this unit to operate.
• Turn the volume to MIN for a while.
Sound quality is bad
(sound is distorted).
• The input level is set to high.
• Turn the VOLUME control knob and set the
input 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 con-
nection 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
t h e r e m o t e c o n t r o l
unit do not light.
