unit, size of grounding conductors, location of antenna-discharge
unit, connection to grounding electrodes, and requirements for the
grounding electrode (see gure).
15. Lightning: For added protection for this product, unplug it from the
wall outlet and disconnect the antenna or cable system during a
lightning storm or when it is left unattended and unused for long periods of time. This will prevent damage to the product due to lightning
or power-line surges.
16. 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 in-

often require extensive work by a qualied technician to restore the
product to its normal operation; e) if the product has been dropped or
damaged in any way; 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
that your service technician has used replacement parts specied
by the manufacturer or have the same characteristics as the original
part. Unauthorized substitutions may result in re, 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 ensure
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.
