Notes
• Use speakers with an impedance of 4 to 8 ohms, and
with adequate power handling capacities. Otherwise,
the speakers may be damaged.
• Do NOT connect the speakers in parallel.
• Do NOT connect the terminals of speaker system to the
car chassis.
RESET SWITCH
• Press reset switch once, after making all connections.
If your vehicle is
not fitted with this type of connector you
must purchase the accessory pack available from your car
radio realer.
Precaution on making connections
Before connecting, make sure that the ignition switch is set
to OFF, and remove the terminal of the battery to avoid
short circuits.
Caution
Make correct connections as illustrated in the connection
diagram.
Never use the cord of each speaker in common. When
replacing the fuse, be sure to use one whose amperage
rating is identical. Use of a fuse of higher amperage may
cause serious damage to the unit.
This unit is designed for negative ground 12-V DC operation
only.
NEVER! Connect the cord of each speaker in common
to ground.

NOTE
In addition to this operating instructions manual,
be sure to refer to the labels on the unit as well.
PRECAUTIONS
• This unit is designed to be operated on a 12-
volt DC negative-ground electrical system only.
• To prevent short-circuiting, disconnect the nega-
tive car battery terminal until the unit has been
mounted and connected completely.
• When replacing the fuse, be sure to use one
whose amperage rating is identical. Use of a
fuse of higher amperage may cause serious
damage to the unit.
• Do NOT attempt to disassemble this unit. Laser
rays from the optical pickup are dangerous to
the eyes.
• Make sure that pins or other foreign objects do
not get inside the unit; they may cause malfunctioning, or a safety hazard such as electrical shock or exposure of laser rays.
• If you park your car in direct sunlight it may
result in a considerable rise in temperature inside the car. Allow the car to cool off before
operating the unit.
• Keep the volume at such a level that you can
hear outside warning sounds (horns, sirens, etc.).
• The apparatus shall not be exposed to dripping
or splashing.
CAUTION
Modifications or adjustments to this product, which
are not expressly approved by the manufacturer,
may void the user's right or authority to operate
this product.
NOTE ON CDs
• A defective or soiled disc inserted into the unit
can cause sound to drop out during playback.
• Handle the disc by holding its inner and outer
edges.
• Do NOT touch the surface of the unlabeled
side of the disc.
• Do NOT stick paper or tape etc. on the surface.
• Do NOT expose the disc to direct sunlight or
excessive heat.
• Clean the disc before playback. Wipe the disc
from the centre outward with a cleaning cloth.
• NEVER use solvents such as benzine or alcohol
to clean the disc.
• Smaller 3-inch (8cm) CDs can not be played on
this unit. And do not use adaptor as it may cause
malfunctioning.
• Do not use irregular shape CDs (example :
heart -shaped, octagonal ones). It may result in
malfunction.
INCORRECT WIRING.
The manufacturer is not responsible for any
defect that may occur due to incorrect wiring
of this product.
Never connect the cord of each speaker in
common to ground.
• This unit is designed only for negative ground 12V DC operation. The equipment can be used safely
if the negative terminal of the battery is connected to the vehicle metal work.
• Do not use speakers of impedance less than 4 ohms and do not allow the speaker wires to be shorted
together when the unit is switched on, otherwise it may overload or burn out the power amplifier
stage.
• If the car interior is extremely hot, for example after being parked in the sun, do not use the player
until the car has been driven for a while to cool off the interior.
Caution Vauxhall owners:
Vauxhall do not follow the normal ISO wiring convention which will cause the unit to lose the radio
preset memories each time the ignition switch is turned off. To prevent such occurrences swap over the
Red ignition and Orange Memory wires in the bullet connectors attached to the wiring harness of the car
radio.
PRECAUTIONS AND MAINTENANCE
IMPORTANT NOTE:
* This unit develops high power output to the front speakers. It is very important that you confirm the
front speakers fitted in your vehicle are capable of handling this power.
* If after directly connecting the unit via the vehicles ISO connector plugs it does not appear to work
(fails to power up), disconnect the Orange lead bullet connector and reconnect it to the twin bullet
connector socket on the RED wire. Try the unit again it should power up and can be used normally.
Note this phenomenon is most frequent in Volkswagen/Audi and Vauxhall vehicles.
