Precautions Before Connecting The System; Before Installing This Product; To Prevent Damage - Pioneer DMH-AF555BT Quick Start Manual

NEVER SERVICE THIS PRODUCT YOURSELF.
Installing or servicing this product and its
connecting cables may expose you to the
risk of electric shock or other hazards, and
can cause damage to this product that is
not covered by warranty.
Precautions before
connecting the system
WARNING
Do not take any steps to tamper with or
disable the handbrake interlock system
which is in place for your protection.
Tampering with or disabling the
handbrake interlock system could result in
serious injury or death.
CAUTION
• Secure all wiring with cable clamps or
electrical tape. Do not allow any bare
wiring to remain exposed.
• Do not directly connect the yellow lead of
this product to the vehicle battery. If the
lead is directly connected to the battery,
engine vibration may eventually cause
the insulation to fail at the point where
the wire passes from the passenger
compartment into the engine
compartment. If the yellow lead's
insulation tears as a result of contact with
metal parts, short-circuiting can occur,
resulting in considerable danger.
• It is extremely dangerous to allow cables
to become wound around the steering
column or gearstick. Be sure to install this
product, its cables, and wiring away in
such so that they will not obstruct or
hinder driving.
• 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.
Before installing this
product
• 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.

To prevent damage

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.
ACC position No ACC position
• 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.
• The graphical symbol placed on
the product means direct current.
Notice for the blue/
white lead
• When the ignition switch is turned on
(ACC ON), a control signal is output
through the blue/white lead. Connect to
an external power amp's system remote
control terminal, the auto-aerial relay
control terminal, or the aerial booster
power control terminal (max. 300 mA 12
V DC). The control signal is output
through the blue/white lead, even if the
audio source is switched off.
