Cause
• The fuse is blown.
• The power supply pin (yellow) of the 10-pin con-
nection cord is not connected.
• 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 completely.
• The negative ⊖ cable of the car battery is discon-
nected.
• The attenuator of the audio components is set to
ON.
• The VOLUME control is set to the MIN position.
• The speaker cords are connected improperly.
• Connection terminals are connected improperly.
• The input level is set to low.
• Connection terminals are connected improperly.
• Large power input causes the protection circuit
for this unit to operate.
• The input level is set to high.
• The speaker cords are connected with incorrect
positive ⊕/negative ⊖ polarity.
• The grounding pin (black) of the 10-pin connec-
tion cord is poorly contacted.
• The remote control cord is unplugged.
• 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).
• 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 connect
the ⊖ cable to the battery.
• Check the connections of all cords, then connect
the ⊖ cable to the battery.
• Switch the attenuator OFF.
• Increase the volume to an optimum level (on
page 7).
• Connect the cords correctly by referring to the
connection example (on page 4).
• Insert the connectors or jacks all the way in to
the terminals.
• Turn the VOLUME control knob and set the input
level to an optimum level.
• Plug the cord into the REMOTE terminal.
• Check that the RCA cord is connected properly.
• Turn the volume to MIN for a while.
• Turn the VOLUME control knob and set the input
level to an optimum level.
• 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.
• Plug the cord into the REMOTE terminal.
• Insert the connector all the way in.
