15.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.
16.Overloading - Do not overload wall outlets and exten- sion cords as this can result in a risk of fire or electric shock.
17.Object and Liquid Entry - Never push objects of any kind into this unit 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 unit.
18.Servicing - Do not attempt to service this unit yourself as opening or removing covers may expose you to dan- gerous voltage or other hazards. Refer all servicing to qualified service personnel.
19.Damage Requiring Service - Unplug this unit from the wall outlet and refer servicing to qualified service per- sonnel under the following conditions:

e.If the unit has been dropped or damaged in any way.
f.When the unit exhibits a distinct change in performance, this indicates a need for service.
20.Replacement Parts - When replacement parts are required, be sure the service technician has used replace- ment parts specified by the manufacturer that have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric shock, injury to persons or other hazards.
21.Safety Check - Upon completion of any service or repairs to this unit, ask the service technician to perform routine safety checks to determine that the unit is in proper operating condition.
