Precautions
Your new product and this manual
Do not operate this product, any applications, or the rear
view camera option (if purchased) if doing so will divert your
attention in any way from the safe operation of your vehicle.
Always observe safe driving rules and follow all existing
traffic regulations. If you experience difficulty in operating
this product or reading the display, park your vehicle in a
safe location and apply the handbrake before making the
necessary adjustments.
Do not install this product where it may
(i) obstruct the driver’s vision,
(ii) impair the performance of any of the vehicle’s operating
systems of safety features, including airbags, hazard lamp
buttons, or
(iii) impair the driver’s ability to safely operate the vehicle.
In some cases, it may not be possible to install this product
because of the vehicle type or the shape of the vehicle
interior.
The graphical symbol

direct current.
Important safeguards
CAUTION
Pioneer does not recommend that you install this
product yourself. This product is designed for
professional installation only. We recommend that only
authorised Pioneer service personnel, who have special
training and experience in mobile electronics, set up and
install this product. 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 product with a 12-volt battery and negative ground-
ing only. Failure to do so may result in a fire or malfunction.
To avoid shorts in the electrical system, be sure to discon-
nect the (–) battery cable before installation.
To prevent damage
WARNING
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 product.
The black lead is earth. Please earth this lead separately
from the earth of high-current products such as power
amps. Do not earth more than one product together with
the earth from another product. For example, you must
separately earth any amp unit away from the earth of this
product. Connecting grounds together can cause a fire
and/or damage the products if their grounds became
detached.
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.
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 termi-
nal (max. 300 mA 12 V DC). The control signal is output through
the blue/white lead, even if the audio source is switched off.
Important
When this product is in “
Power OFF
” mode, the control signal
is also turned off. If “
Power OFF
” mode is cancelled, the
control signal is output again and the aerial is extended with
the auto aerial function (if the aerial is being used). Be careful
so that the extended aerial does not come into contact with
any obstacles.
