CAUTION STATEMENTS

WARNING: TO PREVENT FIRE OR

ELECTRICAL SHOCK DO NOT EXPOSE

THIS PRODUCT'S AC ADAPTER OR AMPLIFIER

TO RAIN OR MOISTURE.

¡WARNING!

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION:

TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT

REMOVE COVER OF AC ADAPTER OR AMPLIFIER.

NO USER-SERVICABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED PERSONNEL.

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.

The lightning flash with arrow head symbol, within an equi-

lateral 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 in-

tended to alert the user to the presence of important operat-

ing and maintenance (servicing) instructions in the literature

accompanying the appliance.

WARNING:

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK,

DO NOT EXPOSE THIS PRODUCT'S AC ADAPTER OR

AMPLIFIER TO RAIN OR MOISTURE. DO NOT OPEN

THE CABINET, REFER SERVICING TO QUALIFIED

PERSONNEL ONLY.

CAUTION:

TO PREVENT ELECTRIC SHOCK, DO NOT USE THE AC

ADAPTER WITH AN EXTENSION CORD RECEPTACLE

OR OTHER OUTLET UNLESS THE BLADES OF THE AC

ADAPTER CAN BE FULLY INSERTED TO PREVENT

BLADE EXPOSURE.

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 LAIS-

SER AUCUNE PARTIE A DECOUVERT.

IMPORTANT SAFETY INSTRUCTIONS

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 grounding-type

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.
