Make sure that the cables and wires will
not interfere with or become caught in
any of the vehicle’s moving parts,
especially the steering wheel, gearstick,
handbrake, sliding seat tracks, doors, or
any of the vehicle’s controls.
•
Do not route wires where they will be
exposed to high temperatures. If the
insulation heats up, wires may become
damaged, resulting in a short circuit or
malfunction and permanent damage to
the product.
•
Do not shorten any leads. If you do, the
protection circuit (fuse holder, fuse
resistor or filter, etc.) may fail to work
properly.
•
Never feed power to other electronic
products by cutting the insulation of the
power supply lead of this product and
tapping into the lead. The current
capacity of the lead will be exceeded,
causing overheating.
•
Use this unit with a 12-volt battery and
negative earthing only. Failure to do so
may result in a fire or malfunction.
•
To avoid shorts in the electrical system,
be sure to disconnect the (–) battery
cable before installation.
WARNING
•
When speaker output is used by 4
channels , use speakers over 50 W
(Maximum input power) and between 4
Ω to 8 Ω (impedance value). Do not use 1
Ω to 3 Ω speakers for this unit.
•
The black cable is earth. When installing
this unit or power amp (sold separately),
make sure to connect the earth wire first.
Ensure that the earth wire is properly
connected to metal parts of the car’s
body. The earth wire of the power amp
and the one of this unit or any other
device must be connected to the car
separately with different screws. If the
screw for the earth wire loosens or falls
out, it could result in fire generation of
smoke or malfunction.
•
When replacing the fuse, be sure to only
use a fuse of the rating prescribed on this
product.
•
This product cannot be installed in a
vehicle without ACC (accessory) position
on the ignition switch.
•
To avoid short-circuiting, cover the
disconnected lead with insulating tape. It
is especially important to insulate all
unused speaker leads, which if left
uncovered may cause a short circuit.
•
For connecting a power amp or other
devices to this product, refer to the
manual for the product to be connected.
