5. Do not use this apparatus near water.
6. Clean only with a dry cloth.
7. Do not block any of the ventilation openings. Install in accordance
with the manufacturers instructions.
8. Do not install near any heat sources such as radiators, heat regis-
ters, stoves, or other apparatus (including amplifiers) that produce
heat.
9. Do not defeat the safety purpose of the polarized or grounding-
type plug. A polarized plug has two blades with one wider than
the other. A grounding type plug has two blades and third ground-
ing prong. The wide blade or third prong are provided for your
safety. When the provided plug does not fit into your outlet, con-
sult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particu-
larly at plugs, convenience receptacles, and the point where they
exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with a cart, stand, tripod, bracket, or table
specified by the manufacturer, or sold with the ap-
paratus. When a cart is used, use caution when moving
the cart/apparatus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for
long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is
required when the apparatus has been damaged in any way, such
as power-supply cord or plug is damaged, liquid has been spilled
or objects have fallen into apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has
been dropped.
15. This product may contain lead and mercury. Disposal of these
materials may be regulated due to environmental considerations.
For disposal or recycling information, please contact your local
authorities or the Electronic Industries Alliance: www.eiae.org
16. Damage Requiring Service - The appliance should be serviced
by qualified service personnel when:
A. The power supply cord or the plug has been damaged; or
B. Objects have fallen, or liquid has been spilled into the appli-
ance; or
C. The appliance has been exposed to rain; or
D. The appliance does not appear to operate normally or
exhibits a marked change in performance; or
E. The appliance has been dropped, or the enclosure damaged.
17. Tilt/Stability - All televisions must comply with recommended
international global safety standards for tilt and stability properties
of its cabinet design.
• Do not compromise these design standards by applying exces-
sive pull force to the front, or top, of the cabinet which could ulti-
mately overturn the product.
• Also, do not endanger yourself, or children, by placing electron-
ic equipment/toys on the top of the cabinet. Such items could
unsuspectingly fall from the top of the set and cause product dam-
age and/or personal injury.
18. Wall or Ceiling Mounting - The appliance should be mounted to
a wall or ceiling only as recommended by the manufacturer.
19. Power Lines - An outdoor antenna should be located away from
power lines.
20. Outdoor Antenna Grounding - If an outside antenna is connect-
ed to the receiver, 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 Electric Code, ANSI/NFPA No. 70-
1984, 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 connectors, location
of antenna-discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode. See Figure below.
21. Object and Liquid Entry - Care should be taken so that objects
do not fall and liquids are not spilled into the enclosure through
openings.

Note to the 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 build-
ing, as close to the point of cable entry as practical.
