(servicing) instructions in the literature
accompanying the appliance.
WARNING: To prevent fire or shock hazard, do not
expose this appliance to rain or moisture
Power plug
When disconnecting the power cord from the
power outlet, always take hold of the plug, and
not the wire, and pull free. Never connect or
disconnect the power plug with wet hands since
you may receive an electric shock.
Remember to disconnect the power plug from
the power outlet when you do not intend to use
the unit for a prolonged period of time.
* Locations exposed to direct sunlight or near objects
radiating heat such as heating appliances.
* Locations exposed to moisture or humidity.
* Locations with poor ventilation exposed to dust and
dirt.
* Locations which are unstable and not perfectly flat or
which are susceptible to vibration.
Do not wipe with thinners
Wipe the panels and case from time to time
with a soft cloth. Using any kind of thinner,
alcohol or volatile liquid will mar the surface,
cause blotching on the exterior and erase the
markings and should therefore be avoided. Do

CONNECTIONS
Connection precautions
When connecting, either disconnect the power plug
from the power outlet or turn off the unit’s power
using the POWER switch.
Check the left and right channels and connect properly
(Left to L and Right to R).
Insert the plugs securely. Improper connection can lead
to the generation of noise.

PROCESSOR terminals
These terminals are used to connect a graphic equalizer or
sound processor. They also come in handy for connecting
an AV (audio/video) selector unit.
Use pin-plug cords to connect the REC terminals to the
AV1/AV2 terminals
These terminals have an electrical performance which is
equivalent to that of the CD terminals and the TUNER
terminals which means that they can be used as the audio
output terminals for a video disc player or TV tuner.
Connect these terminals to the OUTPUT terminals on the
component using the pin-plug cord.

CONNECTIONS
Speaker systems
Connect the speaker systems to the SPEAKERS terminals
on the rear panel of the unit with the speaker cords.
When viewed from the front (the listening position), the
speaker mounted on the left should be connected to the L
terminals, and the speaker mounted on the right should be
connected to the R terminals. Be sure to connect the
polarities of the speaker systems and the SPEAKER
terminals correctly (+ to +, - to -). If the polarity of one of
the speaker systems is connected improperly, sound in the
central area between the speakers will appear to be missing,
and the position of the instruments will not be clear,
resulting in a loss of stereo directionality; so take care
when connecting.
* When connecting, do not allow the conductor of the
speaker cords to be exposed from the terminals and come
into contact with other terminals.
PHONO
Connect the turntable’s output cord L (white) plug to the L
PHONO terminal and the R (red) plug to the R terminal.
If your turntable is equipped with a grounding cable,
connect it to the unit’s GND terminal. But disconnect it if
you notice increased hum.
