9. VENTILATION - Slots and openings in the cabinet back or bottom are provided for ventilation, to
ensure reliable operation of the unit and to protect it from overheating. These openings should
never be blocked by placing the unit on a bed, sofa, rug, or other similar surface. This unit should
never be placed near or over a radiator or heat source. This unit should not be placed in a built-in
installation, such as a bookcase, or rack unless proper ventilation is provided or the manufacture’s
instructions have been adhered to.
10. POWER SOURCE - This unit should be operated only from the type of power source indicated
on the rating plate. If you are not sure of the type of power supply to your home, consult your
appliance dealer or local power company. For units intended to operate from battery power, or
other sources, refer to the operating instructions.
11. POLARIZATION - This unit is equipped with a polarized alternating current line plug (a plug
having one blade wider than the other). This plug will fit into the power outlet only one way. This
is a safety feature. If you are unable to insert the plug fully into the outlet, try reversing the
plug. If the plug still fails to fit, contact your electrician to replace your obsolete outlet. Do not
defeat the safety purpose of the polarized plug.
12. POWER-CORD PROTECTION - Power supply cords should be routed so that they are not likely to
be walked on or pinched by items placed upon or against them, paying particular attention to
cords at plugs, convenience receptacles, and the point where they exit from the appliance.
13. LIGHTNING - To protect your unit during a lightning storm, or when it is left unattended and
unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or
cable system. This will prevent damage to the unit due to lightning and power line surges.
14. 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 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.
15. OVERLOADING - Do not overload wall outlets and extension cords as this can result in a risk of
fire or electric shock.
16. OBJECT AND LIQUID ENTRY - Do not push objects through any openings in this unit as they may
touch dangerous voltage points or short out parts that could result in fire or electric shock.
Never spill or spray any type of liquid into the unit.
17. OUTDOOR ANTENNA GROUNDING - If an outside antenna or cable system is connected to the unit,
be sure the antenna or cable system is grounded to provide some protection against voltage
surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA 70,
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 electrode.
18. SERVICING - Do not attempt to service this unit yourself as opening or removing covers
may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service
personnel.
19 .DAMAGE REQUIRING SERVICE - Unplug this unit from the wall outlet and refer servicing to qualified
service personnel under the following conditions:
A. When the power-supply cord or plug is damaged.
B. If liquid has been spilled, or objects have fallen into the unit.
C. If the unit has been exposed to rain or water.
D. If the unit does not operate normally by following the operating instructions. Adjust only
those controls that are covered by the operating instructions, as an improper adjustment
of other controls may result in damage and will often require extensive work by a qualified
technician to restore the unit to Its normal operation.
E. If the unit has been dropped or the cabinet has been damaged.
F. When the unit exhibits a distinct change in performance, this indicates a need for service.
20. REPLACEMENT PARTS - 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.
21. SAFETY CHECK - 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.
22. HEAT - The product should be situated away from heat sources such as radiators, heat
registers, stoves, or other products (including amplifiers) that produce heat.
23. NOTE TO CATV SYSTEM INSTALLER - This reminder is provided to call the CATV system installer’s
attention to Article 820-40 of the NEC that 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 cable entry as practical.
RISK OF ELECTRIC SHOCK
DO NOT OPEN

equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude
to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in
the literature accompanying the appliance.
WARNING: TO REDUCE THE RISK OF ELECTRIC SHOCK DO NOT

Double insulation this is class II apparatus.
The mains plug used as the disconnect device. The disconnect device shall remain readily operable.
WARNING: To reduce the risk of electric shock do not expose this apparatus to rain or moisture
and objects filled with liquids, such as vases, should not be placed on this apparatus.
WARNING: According to the industrial standards, there are a certain number of defective pixels
both bright and dark that are acceptable. Although we produce panel with more than 99.99
percent active cells, there still may be some cells that do not produce light or remain lit. For more
