CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

Make certain that the

AC outlet is properly grounded.

Do not use an adapter plug with this product.

The lightning flash with arrowhead 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.

1.	Read Instructions. All the
safety and operating instruc-
tions should be read before

placing the product on a bed,

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.

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 par-

ticular attention to cords at

plugs, convenience recepta-

cles, and the point where they

exit from the product.

14. Nonuse Periods. The

power cord of the product

should be unplugged from the

mation with regard to proper grounding of the mast and supporting structure, ground- ing of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna-discharge unit, connection to grounding elec- trodes, and requirements for the grounding electrode. See Figure 1.

16. Lightning. For added pro-

tection 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.

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.

18. Overloading. Do not over-

load wall outlets, extension

20.Servicing. Do not attempt to service this product your- self, as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.

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

a. The power-supply cord or the plug has been damaged; or b. Objects have fallen onto, or liquid has been spilled into, the product; or

c. The product has been exposed to rain or water; or d. The product does not oper- ate normally when 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; or

e. The product has been dropped or damaged in any way; or

f.The product exhibits a dis- tinct change in performance; this indicates a need for service.

22.Replacement Parts. When replacement parts are required, be sure the service technician has used replacement parts specified by the manufacturer or that have the same charac- teristics as the original part. Unauthorized substitutions may result in fire, electric shock or other hazards.

23.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.

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

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

cleaning. Do not use liquid

cleaners or aerosol cleaners.

Use a damp cloth for cleaning.

6. Attachments. Do not use

attachments 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

sofa, rug or other similar sur-

face. This product should not

15. Outdoor Antenna

Grounding. If an outside

antenna or cable system is

connected to the product, be

sure the antenna or cable sys-

tem is grounded so as to pro-

vide some protection against

voltage surges and built-up

static charges. Article 810 of

the National Electrical Code,

ANSI/NFPA 70, provides infor-

cords, or integral convenience

receptacles, as this can result

in a risk of fire or electric

shock.

19. 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.
