WARNING

•  If you connect the ignition wire (red) and the 

battery wire (yellow) to the car chassis (ground), 
you may cause a short circuit, that in turn may 
start a fire. Always connect those wires to the 
power source running through the fuse box.

•  Do not cut out the fuse from the ignition wire 

(red) and the battery wire (yellow). The power 
supply must be connected to the wires via the 
fuse. 

After the Installation

After the installation, perform the Initial Setup 
by referring to the instruction manual.

¤

•  Mounting and wiring this product requires 

skills and experience. For best safety, leave the 
mounting and wiring work to professionals.

•  Make sure to ground the unit to a negative 12V 

DC power supply.

•  Do not install the unit in a spot exposed to direct 

sunlight or excessive heat or humidity. Also avoid 
places with too much dust or the possibility of 
water splashing.

•  Do not use your own screws. Use only the screws 

provided. If you use the wrong screws, you could 
damage the unit.

•  If the power is not turned ON ("Miswiring 

DC Offset Error", "Warning DC Offset Error" is 
displayed), the speaker wire may have a short-
circuit or touched the chassis of the vehicle and 
the protection function may have been activated. 
Therefore, the speaker wire should be checked.

•  If your car’s ignition does not have an ACC 

position, connect the ignition wires to a power 
source that can be turned on and off with the 
ignition key. If you connect the ignition wire to 
a power source with a constant voltage supply, 
such as with battery wires, the battery may be 
drained.

•  If the console has a lid, make sure to install the 

unit so that the faceplate will not hit the lid when 
closing and opening.

•  If the fuse blows, first make sure the wires aren’t 

touching to cause a short circuit, then replace the 
old fuse with one with the same rating.
