- To reduce the risk of fire and electric shock, do not expose this product to rain or moisture.
WARNING
This device has been tested and found to comply with the limits for a Class B device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in home
environment as well as in a commercial, industrial or business environment. This equipment can generate, use and
radiate radio frequency energy and, if not installed and used in accordance with the instruction, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or
more of the following measures :
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.

Precaution
OWNER'S MANUAL 5
Follow all operating and use
instructions.
Do not use the TV where contact
with or immersion in water is a
possibility, such as near bath tubs,
sinks, washing machines,
swimming pools, etc.
Setting CAUTION
Ground outdoor antennas. If an outside antenna or cable system is connected to the TV, be sure the antenna or cable
system is grounded so as to provide some protection against voltage surges and built-up static charges. Section 810 of
the National Electrical Code, ANSI/NFPA No.70-1984, provides information about 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 electrode.
Do not place an outside antenna in
the vicinity of overhead power lines,
or other electric light or power
circuits.
- This may cause an electric shock.
There should be enough distance
between an outside antenna and
power lines to keep the former from
touching the latter even when the
antenna falls.
- This may cause an electric shock.
Bend antenna cable between
inside and outside building to
prevent rain from flowing in.
- This may cause water damaged
inside the TV and could give an
electric shock.
Avoid overhead power lines. An outside
antenna system should not be placed 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,
be extremely careful to keep from touching
the power lines or circuits. Contact with
such lines can be fatal.
In case of the following cases, unplug the unit from the wall outlet and contact qualified service center.
- when power supply cord or plug is damaged.
- If liquid has been spilled on the unit or if alien objects have fallen into the unit.
- If the TV has been exposed to rain or water.
- If the TV does not operate normally by following the operating instructions.
- If the TV dropped or the cabinet has been damaged.
- When the TV exhibits a distinct change in performance.
NO!!
