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 swim-

ming 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 recom-

mended 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 sup-

plied 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

alternatingcurrent 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.

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.

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 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 appliance.

WARNING:

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO NOT EXPOSE THIS

APPLIANCE TO RAIN OR MOISTURE. DO NOT OPEN THE CABINET, REFER

SERVICING TO QUALIFIED PERSONNEL ONLY.

CAUTION:

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.

! CAUTION !

DO NOT OPEN

14. Outdoor Antenna Grounding—If an outside antenna or cable system is connect-

ed 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 elec-

trode. 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.

17. Overloading—Do not overload wall outlets, extension cords, or integral conve-

nience 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 im-

proper adjustment of other controls may result in damage and will often require ex-

tensive 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.
