SAFETY INSTRUCTIONS
1. Read Instructions – All the safety and operating instructions
should be read before the appliance is operated.
2. Retain Instructions – The safety and operating instructions
should be retained for future reference.
3. Heed Warnings – All warnings on the appliance and in the
operating instructions should be adhered to.
4. Follow Instructions – All operating and use instructions

6. Carts and Stands – The appliance should be used only with
a cart or stand that is recommended by the manufacturer.
6A. An appliance and cart
combination should be
moved with care.
Quick stops, excessive
force, and uneven
surfaces may cause
the appliance and cart
combination to overturn.
7. Wall or Ceiling Mounting – The appliance should be
mounted to a wall or ceiling only as recommended by the
manufacturer.
8. Ventilation – The appliance should be situated so that its
location or position does not interfere with its proper
ventilation. For example, the appliance should not be
situated on a bed, sofa, rug, or similar surface that may
block the ventilation openings; or, placed in a built-in
installation, such as a bookcase or cabinet that may impede
the flow of air through the ventilation openings.
9. Heat – The appliance should be situated away from heat
sources such as radiators, heat registers, stoves, or other
appliances (including amplifiers) that produce heat.
10. Power Sources – The appliance should be connected to a
power supply only of the type described in the operating
instructions or as marked on the appliance.
11. Grounding or Polarization – Precautions should be taken so
that the grounding or polarization means of an appliance is
not defeated.
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.
14. Cleaning – The appliance should be cleaned only as
recommended by the manufacturer.
15. Power Lines – An outdoor antenna should be located away
from power lines.
16. Outdoor Antenna Grounding – If an outside antenna is
connected to the receiver, be sure the antenna system is
grounded so as to provide some protection against voltage
surges and built-up static charges. Article 810 of the
National Electrical Code, ANSI/NFPA 70, provides
information with regard 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.
See Figure A.
17. Nonuse Periods – The power cord of the appliance should
be unplugged from the outlet when left unused for a long
period of time.
18. Object and Liquid Entry – Care should be taken so that
objects do not fall and liquids are not spilled into the
enclosure through openings.
19. 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
appliance; 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
