This equipment has been tested and found to
comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable
p
rotection against harmful interference in a
residential installation. This equipment
generates, uses, and can radiate radio frequency
energy and, if not installed and used in
accordance with the instructions, may cause
harmful interference to radio communications.
However, there is no guarantee that interference
wi
ll not occur in a particular installation. If this
equipment does cause harmful interference to
radio or television reception, which can be
determined by turning the equipment off and
on, the user is encouraged to try to correct the
interference by one or more of the following
measures:
R
eorient or relocate the receiving antenna.
ncrease the separation between the
I
equipment and receiver.
C
onnect the equipment into an outlet on a
circuit different from that to which the receiver
is connected.
C
onsult the dealer or an experienced radio/TV
technician for help.
You are cautioned that any changes or
m
odifications not expressly approved in this
manual could void your authority to operate this
equipment.

Connections
Before making any connections, disconnect the
ground (earth) terminal of the car battery to avoid
short circuits.
I
f your car is equipped with a computer system for
navigation or some other purpose, disconnecting
the ground (earth) wire from the car battery may
damage the computer memory. Leaving the
ground (earth) wire connected and disconnecting
the +12 V power supply wire until all the other
wires have been connected may prevent short
circuits.
Be su
re to use speakers with an adequate power
rating. If you use small capacity speakers, they
may be damaged.
Do
not connect the terminal of the speaker
system to the car chassis, and do not connect the
terminal of the right speaker with that of the
left speaker.
In
stall the input and output cords away from the
power supply wire. Running them close together
may generate interference noise.

B
e sure to connect the ground (earth) wire of the
unit securely to a metal point of the car. A loose
connection may cause a malfunction of the
amplifier.
B
e sure to connect the remote control wire of the
car audio unit to the remote input (REM) wire of
the supplied power connection cable.
W
hen using a car audio unit without a remote
output for the amplifier, connect the remote input
(REM) wire of the supplied power connection
cable to the accessory power supply.
U

to the car (ground (earth) to chassis) are of a wire
gauge at least equal to that of the main power
wire connected from the battery to the amplifier.
D
uring full-power operation, a current of more
than 15 A will run through the system. Therefore,

Maintenance
Fuse Replacement
When replacing the fuse, be sure to use one
matching the amperage stated above the fuse
holder. If the fuse blows, check the power
connection and replace the fuse. If the fuse blows
again after replacement, there may be an internal
malfunction. In such a case, consult your nearest
Sony dealer.
Warning
Never use a fuse with an amperage rating
exceeding the one supplied with the unit as this
could damage the unit.
