IMPORTANT INFORMATION CONT'D

10.Grounding or Polarization - This video product is equipped with a polarized alternating - current line plug (a plug having one blade wider than the other). This plug will fit into the power socket only one way. This is a safety feature. If you are unable to insert the plug full 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.

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 appliance dealer or local power company.

12.Power-cord Protection - Power-supply cords should be routed so they are not likely to be walked on or pinched by items placed upon or against them. Pay particular attention to cords and plugs, convenience receptacles, and the point where they exit from the appliance.

13.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.

14.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.

15.Overloading - Do not overload wall outlets and extension cords as this can result in risk of fire or electric shock.

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

17.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.

18.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 instruction. Adjust only those controls that are covered by the operating instructions.

21.Outdoor Antenna Grounding - Before attempting to

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

a.Use No.10 AWG (5.3mm ) copper, No.8 AWG (8.4mm (aluminum, No.7 AWG (10mm ) copper-clad steel or bronze

wire or larger, as ground wire.

b.Secure antenna lead-in and ground wires to house with stand-off insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.

c.Mount antenna discharge unit as close as possible to where lead-in enters house.

d.A driven rod may be used as the grounding electrode where other types of electrode systems do not exist. Refer to the National Electrical Code, ANSI/NFPA 70-1984 for information.

e.Use jumper wire not smaller than No.6 AWG (13.3mm ) copper or equivalent, when a separate antenna grounding electrode is used.

NOTE TO THE CATV SYSTEM INSTALLER:

THIS REMINDER IS PROVIDED TO CALL THE CATV SYSTEM INSTALLER’S ATTENTION TO ARTICLE 820 - 22 OF THE NEC THAT PROVIDES GUIDELINES FOR PROPER GROUNDING AND, IN PARTICULAR, SPECI- FIES THAT THE CABLE GROUND SHALL BE CON- NECTED TO THE GROUNDING SYSTEM OF THE BUILD- ING, AS CLOSE TO THE POINT OF CABLE ENTRY AS PRACTICAL.
