Safety Warnings
16. 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 eliminate touching
power lines or circuits as contact might
be fatal.
17. Do not overload wall outlets, extension
cords, or integral convenience
receptacles as this can result in a risk of
fire or electric shock.
18. Never push objects of any kind into this
product through openings as they may
touch short-out parts or dangerous
voltage points that could result in a fire
or electric shock. Never spill liquid of any
kind on the product.
19. If an outside antenna is connected to the
television equipment, be sure the antenna
system is grounded so as to provide
some protection against voltage surges
and built up static charges. Section 810
of the National Electrical Code provides
information with respect to proper
grounding of the mast and supporting
structure, grounding of the lead-in wire
to an antenna discharge unit, size of
grounding conductors, location of antenna
discharge unit, connection to grounding
electrodes, and requirements for the
grounding electrodes.

20. NOTE TO CABLE/TV INSTALLER: This
reminder is provided to call the CATV
system installer’s attention to Article 820-40
of the National Electric Code (U.S.A.).
The code provides guidelines for proper
grounding and, in particular, specifies that
the cable ground shall be connected to
the grounding system of the building, as
close to the point of the cable entry as
practical.
21. When replacement parts are required,
be sure the service technician uses
replacement parts specified by the
manufacturer or those that have the
same characteristics as the original part.
Unauthorized substitutions may result in
fire, electric shock or other hazards.
22. Upon completion of any service or repairs
to this unit, ask the service technician to
perform safety checks to determine that
the unit is in proper operating condition.
23. When you connect the product to other
equipment, turn off the power and unplug
from the wall outlet. Failure to do so may
cause an electric shock and serious
personal injury. Read the owner’s manual
of the other equipment carefully and
follow the instructions when making any
connections.
24. Sudden high volume may cause hearing
or speaker damage. When you use
headphones (if the unit is equipped with
a headphone jack), keep the volume at a
moderate level. If you use headphones
continuously with high volume, you may
suffer hearing damage.
25. Do not allow the product to output
distorted sound for extended periods of
time. This may cause speaker overheating
and fire.
26. The socket-outlet must be installed near
the unit and easily accessible.
27. The mains plug is used as the disconnect
and shall remain readily operable.
