Important Safeguards

CAUTION

All the safety and operating instructions should be read before the appliance is
operated, and should be retained for future reference.
Electrical energy can perform many useful functions. This unit has been engineered
and manufactured to assure your personal safety. Improper use can result in
potential electrical shock or fire hazards. In order not to defeat the safeguards,
observe the following basic rules for its installation, use and servicing.

1

Heed Warnings - All warnings on the appliance and in the operating instructions
should be adhered to.

2

Follow Instructions - All operating and use instructions should be followed.

3

Water and Moisture - The appliance should not be used near water - for
example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet base­ment, or near a swimming pool, etc.

4

Carts and Stands - The appliance should be used only with a cart or stand that is
recommended by the manufacturer.

● An appliance and cart combination should be moved with care.
Quick stops, excessive force, and uneven surfaces may cause
the appliance and cart combination to overturn.

5

Wall or Ceiling Mounting - The appliance should be mounted to a wall or ceiling
only as recommended by the manufacturer.

6

Ventilation - The appliance should be situated so that its location or position does
not interfere with its proper ventilation. For example, the appliance should not be
situated on a bed, sofa, rug, or similar surface that may block the ventilation
openings; or, placed in a built-in installation, such as a bookcase or cabinet that
may impede the flow of air through the ventilation openings.

7

Heat - The appliance should be situated away from heat sources such as
radiators, heat registers, stoves, or other appliances (including amplifiers)
that produce heat.

8

Power Sources - The appliance should be connected to a power supply only of
the type described in the operating instructions or as marked on the appliance.

9

Power-Cord Protection - Power-supply cords should be routed so that they are
not likely to be walked on or pinched by items placed upon or against them,
paying particular attention to cords at plugs, convenience receptacles, and the
point where they exit from the appliance.

10

Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.

11

Power Lines - An outdoor antenna should be located away from power lines.

12

Outdoor Antenna Grounding - If an outside antenna is connected to the receiver ,
be sure the antenna system is grounded so as to provide some protection against
voltage surges and built-up static charges. Section 810 of the National Electrical
Code, ANSI/NFPA No. 70-1984, provides information with respect to proper
grounding of the mast and supporting structure, grounding of the lead-in wire to
an antenna discharge unit, size of grounding conductors, location of antenna­discharge unit, connection to grounding electrodes, and requirements for the
grounding electrode.

Precautions

■

General

● Please ensure that the equipment is positioned in a well-ventilated area and ensure

that there is at least 8" (20 cm) of free space along the sides, top and back of the unit.

8" (20 cm) 8" (20 cm)

● Use the unit on a firm, level surface free from vi-

bration.

● Keep the unit away from direct sunlight, strong mag-

netic fields, excessive dust, humidity and electronic/
electrical equipment (home computers, facsimiles,
etc.) which generates electrical noise.

● Do not place anything on the unit.

● Do not expose the unit to moisture, to tempera-

tures higher than 140°F (60°C) or to extremely low
temperatures.

● If your system does not work properly, disconnect

the AC power cord from the AC outlet. Plug the AC
power cord back in, and then turn on your system.

● In case of an electrical storm, unplug the unit for

safety.

● Hold the AC power plug by the head when remov-

ing it from the AC outlet, as pulling the cord can
damage internal wires.

● Do not remove the outer cover, as this may

result in electric shock. Refer internal service to
your local SHARP service facility.

● This unit should only be used within the range

of 41°F - 95°F (5°C - 35°C).

Warning:

The voltage used must be the same as that specified on this unit.
Using this product with a higher voltage other than that which is specified is dangerous
and may result in a fire or other type of accident causing damage. SHARP will not be
held responsible for any damage resulting from use of this unit with a voltage other
than that which is specified.

■

Volume control

The sound level at a given volume setting depends on speaker efficiency , location and
various other factors.
It is advisable to avoid exposure to high volume levels, which occur while turning the unit
on with the volume control setting up high, or while continually listening at high volumes.

■

Care of compact discs

Compact discs are fairly resistant to damage, however mistracking can occur due to
an accumulation of dirt on the disc surface.
Follow the guidelines below for maximum enjoyment from your CD collection and player .

● Do not write on either side of the disc, particularly the non-label side from which

signals are read. Do not mark this surface.

● Keep your discs away from direct sunlight, heat, and excessive moisture.

● Always hold the CDs by the edges. Fingerprints, dirt, or water on the CDs can

cause noise or mistracking. If a CD is dirty or does not play properly, clean it with a
soft, dry cloth, wiping straight out from the center, along the radius.

NO

■

Cassette tape

● For playback, use normal or low-noise tapes for the best

sound. (Metal or CrO2 tapes are not recommended.)
For recording, use only normal tapes.

● Do not use C-120 tapes or poor-quality tapes, as they may cause

malfunctions.

● Before loading a tape into the cassette compartment, tighten

the slack with a pen or pencil.

Cassettes have removable tabs which prevent accidental record­ing or erasing.
Removing the tab will protect the corresponding side.
Cover the tab holes with adhesive tape to erase or record again.

Bi-amp system:

Each speaker unit has a built-in subwoofer (low frequency range) which is driven sepa­rately from the woofer and tweeter (mid-to-high frequency range). Two independent
amplifiers which have individual frequency characteristics are used.
By amplifying separately the two frequency bands, clearer sound is achieved.
