8 Accessories - Do not place this product on an unstable cart, stand,

tripod, bracket, or table. The product may fall, causing serious injury to
a child or adult, and serious damage to the product. Use only with a
cart, stand, tripod, bracket, or table recommended by the manufac­turer, or sold with the product. Any mounting of the product should
follow the manufacturer’s instructions, and should use a mounting ac­cessory recommended by the manufacturer.

9 A product and cart combination should be moved with

care. Quick stops, excessive force, and uneven surfaces
may cause the product and cart combination to over­turn.

10 Ventilation - Slots and openings in the cabinet are provided for venti-

lation and to ensure reliable operation of the product and to protect it
from overheating, and these openings must not be blocked or cov­ered. The openings should never be blocked by placing the product on
a bed, sofa, rug, or other similar surface. This product should not be
placed in a built-in installation such as a bookcase or rack unless proper
ventilation is provided or the manufacturer’s instructions have been
adhered to.

11 Power Sources - This product should be operated only from the type

of power source indicated on the marking label. If you are not sure of
the type of power supply to your home, consult your product dealer or
local power company. For products intended to operate from battery
power, or other sources, refer to the operating instructions.

12 Grounding or Polarization - This product may be equipped with a

polarized alternating-current line plug (a plug having one blade wider
than the other). This plug will fit into the power outlet only one way.
This is a safety feature. If you are unable to insert the plug fully into the
outlet, try reversing the plug. If the plug should still fail to fit, contact
your electrician to replace your obsolete outlet. Do not defeat the safety
purpose of the polarized plug.

Alternate Warnings - This product is equipped with a three-wire
grounding-type plug, a plug having a third (grounding) pin. This plug
will only fit into a grounding-type power outlet. This is a safety feature.
If you are unable to insert the plug into the outlet, contact your electri­cian to replace your obsolete outlet. Do not defeat the safety purpose
of the grounding-type plug.

13 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 product.

14 Protective Attachment Plug - The product is equipped with an at-

tachment plug having overload protection. This is a safety feature. See
Instruction Manual for replacement or resetting of protective device. If
replacement of the plug is required, be sure the service technician has

IMPORTANT SAFETY INSTRUCTIONS (continued)

15 Outdoor Antenna Grounding - If an outside antenna or cable system

is connected to the product, be sure the antenna or cable system is
grounded so as to provide some protection against voltage surges and
built-up static charges. Article 810 of the National Electrical Code, ANSI/
NFPA 70, provides information with regard 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.

storm, or when it is left unattended and unused for long periods of
time, unplug it from the wall outlet and disconnect the antenna or cable
system. This will prevent damage to the product due to lightning and
power-line surges.

17 Power Lines - An outside antenna system should not be located in the

vicinity of overhead power lines or other electric light or power circuits,
or where it can fall into such power lines or circuits. When installing an
outside antenna system, extreme care should be taken to keep from
touching such power lines or circuits as contact with them might be
fatal.

ENERGY STAR® Program Information

As an ENERGY STAR® Partner, SHARP has determined that this product
meets the

ENERGY STAR® is a U.S. registered mark.

By using
electric bills and use less energy.
That makes good economic sense and it’s good for our environment.

ENERGY STAR® is a U.S. registered mark.

ENERGYSTAR® guidelines for energy efficiency.

WHY PURCHASE
PRODUCTS?

Many Electrical/Electronic Products use energy
both when they are on and when they are off.
Americans spend more than $3 billion a year on
energy consumed by home electronic products when
they are not in use. The new
labeled models will reduce that energy “leakage” by
up to 75 percent. Ultimately, this will mean more
than $1 billion a year in energy savings for
consumers.
The energy savings will help reduce the burning of
fossil fuels and the related carbon dioxide pollution
that contributes to global warming. If every American
family replaced their electronic equipment with

ENERGY STAR® labeled models, it would reduce

air pollution equivalent to eliminating more than two

Precautions

SD-EX220

 General

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

sure that there is at least 4" (10 cm) of free space along the sides, top and back of
the equipment.
(Unless the unit is to be wall mounted.)

4" (10 cm)

z Use the unit on a firm, level surface free from vibra-

tion.

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

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

z Do not place anything on top of the unit.
z Do not expose the unit to moisture, to temperatures higher than 140°F (60°C) or to

extremely low temperatures.

z 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.

z In case of an electrical storm, unplug the unit for safe-

ty.

4" (10 cm) 4" (10 cm) 4" (10 cm)

z Hold the AC power plug by the head when removing it

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

z Do not remove the outer cover, as this may result

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

z This unit should only be used within the range of 41°F - 95°F (5°C - 35°C).

Warning:

z The voltage used must be the same as that specified on th is unit. Us i ng this prod-

uct with a higher voltage other than that which is specified is dangerous and may
result in a fire or other type of accident caus ing 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.

z CD players use a laser pickup which can damage the eyes if viewed directly.

Do not look at the pickup, and do not touch the pickup directly.



Volume control

The sound level at a given volume sett ing depends on speaker efficiency, locat ion
and various other factors. It is advi sable to avoid exposure to high volume level s,
which occurs while turning the unit on with the volume control setting up high, or
while continually listening at high volumes.

Care of compact discs

- Maintenance / Error messages -

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.

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

signals are read. Do not mark this surface.
