IMPORTANT SAFETY INSTRUCTIONS
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in
accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as
radiators, heat registers, 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 a third grounding prong. The wide
blade or the third prong are provided for your safety. If
the provided plug does not fit into your outlet, consult
an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or
pinched particularly 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 the cart, stand, tripod, bracket, or
table specified by the manufacturer, or
sold with the apparatus. When a cart
is used, use caution when moving the
cart/apparatus combination to avoid
injury from tip-over.
13. Unplug this apparatus during light-
ning 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 the apparatus, the apparatus has
been exposed to rain or moisture, does not operate
normally, or has been dropped.
15. This appliance should be mounted to a wall or
ceiling only as recommended by the manufacturer.
16. Care should be taken so that objects do no fall
and liquids are not spilled into the enclosure through
openings.
17. If an outside antenna or cable system is connected
to the video product, 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 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 anten-
na-discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode. See

NOTE: 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.
