7 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.
8 TV sets are provided with ventilation openings in the cabinet to allow heat generated during
operation to be released.
Therefore:
— Never block the bottom ventilation slots of a portable TV set by placing it on a bed, sofa,
rug, etc.
— Never place a TV set in a “built-in” enclosure unless proper ventilation is provided.
— Never cover the openings with a cloth or other material.
— Never place the TV set near or over a radiator or heat register.
9 To avoid personal injury:
— Do not place a TV set on a sloping shelf unless properly secured.
— Use only a cart or stand recommended by the TV set manufacturer.
— Do not try to roll a cart with small casters across thresholds or deep pile carpets.
— Wall or shelf mounting should follow the manufacturer’s instructions, and should use a
mounting kit approved by the manufacturer.
10 Caution children about dropping or pushing objects into the TV set through cabinet
openings. Some internal parts carry hazardous voltages and contact can result in a fire or
electrical shock.
11 Unplug the TV set from the wall outlet before cleaning. Do not use liquid or an aerosol
cleaner.
12 Never add accessories to a TV set that has not been designed for this purpose. Such
additions may result in a hazard.
