Selecting fine audio equipment such as the unit you’ve just purchased is only the start of your
musical enjoyment. Now it’s time to consider how you can maximize the fun and excitement your
equipment offers. This manufacturer and the Electronic Industries Association’s Consumer
Electronics Group want you to get the most out of your equipment by playing it at a safe level.
One that lets the sound come through loud and clear without annoying blaring or distortion—and,
most importantly, without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of
sound. So what sounds “normal” can actually be loud and harmful to your hearing. Guard against
this by setting your equipment at a safe level BEFORE your hearing adapts.
To establish a safe level:
•
Start your volume control at a low setting.
•
Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.
Once you have established a comfortable sound level:
•
Set the dial and leave it there.
Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all,
we want you listening for a lifetime.
We Want You Listening For A Lifetime
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since
hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the
Electronic Industries Association’s Consumer Electronics Group recommend you avoid prolonged
exposure to excessive noise. This list of sound levels is included for your protection.

CAUTION
Never replace the fuse with one of greater
value or rating than the original fuse. Use
of an improper fuse could result in over-
heating and smoke and could cause dam-
age to the product and injury including
burns.
CAUTION
Do NOT install or use your Pioneer ampli-
fier by wiring speakers rated at 4 Ohm (or
lower) in parallel to achieve a 2 Ohm (or
lower) bridged mode (Diagram B).
Amplifier damage, smoke, and overheating
could result from improper bridging. The
amplifier surface could also become hot to
the touch and minor burns could result.
To properly install or use a bridged mode
for a two-channel amplifier and achieve a 4
Ω
load, wire two 8
Ω
speakers in parallel
with Left + and Right - (Diagram A) or use
a single 4
Ω
speaker. For a four-channel
amplifier, follow the speaker output con-
nection diagram for bridging as shown on
the back of your amplifier, and wire two 8
Ω
speakers in parallel to achieve a 4
Ω
load or use a single 4
Ω
speaker per chan-
nel.
If you have any questions or concerns,
please contact your local authorized
Pioneer dealer or call Pioneer customer
service.
WARNING
• Handling the cord on this product or cords associ-
ated with accessories sold with the product will
expose you to lead, a chemical known to the State
of California and other governmental entities to
cause cancer and birth defects or other reproduc-
tive harm.
Wash hands after handling
.
• Always use the special red battery and ground
wire [RD-223], which is sold separately. Connect
the battery wire directly to the car battery positive
terminal (+) and the ground wire to the car body.
• Do not touch the amplifier with wet hands.
Otherwise you may get an electric shock. Also, do
not touch the amplifier when it is wet.
• For traffic safety and to maintain safe driving
conditions, keep the volume low enough so that
you can still hear normal traffic sound.
• Check the connections of the power supply and
speakers if the fuse of the separately sold battery
wire or the amplifier fuse blows. Detect the cause
and solve the problem, then replace the fuse with
another one of the same size and rating.
• To prevent malfunction of the amplifier and
speakers, the protective circuit will cut the power
supply to the amplifier (sound will stop) when an
abnormal condition occurs. In such a case, switch
the power to the system OFF and check the
connection of the power supply and speakers.
Detect the cause and solve the problem.
• Contact the dealer if you cannot detect the cause.
• To prevent an electric shock or short-circuit
during connection and installation, be sure to
disconnect the negative (–) terminal of the battery
beforehand.
• Confirm that no parts are behind the panel when
drilling a hole for installation of the amplifier. Be
sure to protect all cables and important equipment
such as fuel lines, brake lines and the electrical
wiring from damage.
