WARNING:

CAUTION:

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS PRODUCT
TO RAIN OR MOISTURE.
DO NOT OPEN THE CABINET, REFER SERVICING TO QUALIFIED PERSONNEL ONLY.

TO PREVENT ELECTRIC SHOCK, DO NOT USE THIS (POLARIZED) PLUG WITH AN EXTENSION
CORD RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED TO
PREVENT BLADE EXPOSURE.

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.

The lightning flash with arrow head symbol, within
an equilateral triangle, is intended to alert the user
to the presence of uninsulated "dangerous voltage"
within the product's enclosure that may be of
sufficient magnitude to constitute a risk of electric
shock to persons.

The exclamation point within an equilateral triangle
is intended to alert the user to the presence of
important operating and maintenance (servicing)
instructions in the literature accompanying
the product.

ATTENTION:

POUR PREVENIR LES CHOCS ELECTRIQUES, NE PAS UTILISER CETTE FICHE POLARISEE
AVEC UN PROLONGATEUR, UNE PRISE DE COURANT OU UNE AUTRE SORTIE DE COUR­ANT, SAUF SI LES LAMES PEUVENT ETRE INSEREES A FOND SANS EN LAISSER AUCUNE
PARTIE A DECOUVERT.

Important Safety Instructions 3

1. Read Instructions—All the safety and operating instructions should be read
before the product is operated.

2. Retain Instructions—The safety and operating instructions should be
retained for future reference.

3. Heed Warnings—All warnings on the product and in the operating in­structions should be adhered to.

4. Follow Instructions—All operating and use instructions should be followed.

5. Cleaning—Unplug this product from the wall outlet before cleaning. Do not

use liquid cleaners or aerosol cleansers. Use a damp cloth for cleaning.

6. Attachments—Do not use attachments that are not recommended by the
product manufacturer as they may cause hazards.

7. Water and Moisture—Do not use this product near water—for example,
near a bathtub, wash bowl, kitchen sink or laundry tub; in a wet basement; or
near a swimming pool; and the like.

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 ventilation
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 similar surface. This product should not be placed in a built-in installation
such as 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 supplied 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—If this product is equipped with a three-wire grounding­type plug, a plug having a third (grounding) pin, the 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.
12 a. Mise à la terre ou Polarisation—Cet appareil est équipé avec un cordon
d'alimentation à trois fils. Il est a brancher sur une prise ayant un connecteur a
la terre. Assurez-vous que la connection a la terre ne manque pas.

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. 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 antenna-discharge unit, connection to
grounding electrodes, and requirements for the grounding electrode.
See Figure A.

15. Lightning—For added protection for this product during a lightning 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.

16. Power Lines—An outside antenna system should not be located in the
vicinity of overhead power lines, other electric light or power circuits, 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 may be fatal.

17. Overloading—Do not overload wall outlets, extension cords, or integral
convenience receptacles as this can result in a risk of fire or electric shock.

18. Object and Liquid Entry—Never push objects of any kind into this product
through openings as they may touch dangerous voltage points or short-out parts
that could result in a fire or electric shock. Never spill liquid of any kind on the
product.

19. Servicing—Do not attempt to service this product yourself as opening or
removing covers may expose you to dangerous voltage or other hazards. Refer
all servicing to qualified service personnel.

20. Damage Requiring Service—Unplug this product from the wall outlet and
refer servicing to qualified service personnel under the following conditions:

a. When the power-supply cord or plug is damaged,
b. If liquid has been spilled, or objects have fallen into the product,
c. If the product has been exposed to rain or water,
d. If the product does not operate normally by following the operating

instructions. Adjust only those controls that are covered by the operating
instructions as an improper adjustment of other controls may result in damage
and will often require extensive work by a qualified technician to restore the
product to its normal operation,

e. If the product has been dropped or damaged in any way, and
f. When the product exhibits a distinct change in performance—this indicates

a need for service.

21. Replacement Parts—When replacement parts are required, be sure the
service technician has used replacement parts specified by the manufacturer
or have the same characteristics as the original part. Unauthorized substitutes
may result in fire, electric shock or other hazards.

22. Safety Check—Upon completion of any service or repairs to this product,
ask the service technician to perform safety checks to determine that the
product is in proper operating condition.

23. Wall or Ceiling Mounting—The product should be mounted to a wall or
ceiling only as recommended by the manufacturer.

24. Heat—The product should be situated away from heat sources such as
radiators, heat registers, stoves, or other products (including amplifiers) that
produce heat.
