with one wider than the other, while a grounding-type
• Connecting the radio/TV equipment to an outlet
on a different circuit than the one into which the
plug has two blades and one prong. The wide blade
and the prong are safety features. If the provided plug
does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
6. Protect the power cord from being walked on or
pinched, particularly where it is plugged in to an
electrical socket and the point where it exits from the
rear of the device.
7. Only use the attachments and accessories specified

introduced into the enclosure, the device has been
exposed to rain or moisture, the product does not
operate normally or it has been dropped.
11. Never push objects of any kind into this product,
through jacks or other openings, as they may contact
dangerous voltage points or short-circuit components,
thus causing fire or electrical shock.

in close proximity to 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, be extremely careful not to
touch such power lines or circuits, as contact with
them could be fatal.
14. Do not overload wall outlets or extension cord
as this can increase the risk of fire, power outages or
electrical shock.
15. When replacement parts are required, be sure the
service technician has used replacement parts specified
by the manufacturer or with the same characteristics
as the original part. Unauthorized substitutions may
result in fire, electric shock or other hazards.
