IMPORTANT SAFETY INSTRUCTIONS

(Continued from previous page)

19. 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 installation,

Do not overload wall outlets and extension cords as this

can result in a risk of fire or electric shock. It is recom-

mended that appliances be placed upon a dedicated

Article 810 of the National Electrical Code (NEC) (in the U.S.A.) 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 elec- trodes, and requirements for the grounding electrode.

circuit; that is, a single outlet circuit which powers only

that appliance and has no additional outlets or branch

circuits. Overloaded wall outlets, loose or damaged wall

outlets, extension cords, frayed power cords, or dam-

aged or cracked wire insulation are dangerous. Any of

these conditions could result in fire or electric shock.

21. Power Cord

Periodically examine the cord of your appliance, and if

its appearance indicates damage or deterioration,

unplug it, discontinue use of the appliance, and have

the cord replaced with an exact replacement part by

ing, or pinching.

22. Outdoor Use/Wet Location

Warning: To prevent fire or electrical shock hazards, do not expose this product to rain, moisture, or other liquids.

Do not touch the product with wet hands. Do not install this product near flammable objects such as gasoline or candles or expose it to direct air conditioning. Do not expose the product to dripping or splashing, and do not place objects filled with liquids, such as vases, on or over the apparatus (e.g., on shelves above the unit).

23.Grounding

Ensure that you connect the earth ground wire to prevent possible electric shock (i.e., a TV with a three-prong grounded AC plug must be connected to a three-prong grounded AC outlet). If grounding methods are not possi- ble, have a qualified electrician install a separate circuit breaker. Do not try to ground the unit by connecting it to telephone wires, lightning rods, or gas pipes.

24.Outdoor Antenna Grounding

If an outside antenna or cable system is connected to the product, follow the precautions below.

An outdoor antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits or where it can come into con- tact with such power lines or circuits as death or seri- ous injury can occur.

Be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges.

25.Damage Requiring Service

Unplug this product from the wall outlet and refer ser- vicing to qualified service personnel under the follow- ing conditions:

a.If 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 per 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 the cabinet has been damaged.

f.If the product exhibits a distinct change in perfor- mance.

g.If you smell smoke or other odors coming from the product or hear strange sounds.

26.Replacement Parts

When replacement parts are required, be sure the ser- vice technician uses replacement parts specified by the manufacturer or that have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, or other hazards.
