6 If an outside antenna is connected to the TV set, 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 Electrical Code 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 requirements for the grounding electrode.
7 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.
8 TV sets are provided with ventilation openings in the cabinet
to allow heat generated during operation to be released.
Therefore:
— Never block the bottom ventilation slots of a portable TV
set by placing it on a bed, sofa, rug, etc.
— Never place a TV set in a “built-in” enclosure unless
proper ventilation is provided.
— Never cover the openings with a cloth or other material.
— Never place the TV set near or over a radiator or heat register.
9 To avoid personal injury:
— Do not place a TV set on a sloping shelf unless properly secured.
— Use only a cart or stand recommended by the TV set
manufacturer.
— Do not try to roll a cart with small casters across thresh-
olds or deep pile carpets.
— Wall or shelf mounting should follow the manufacturer’s
instructions, and should use a mounting kit approved by
the manufacturer.
USE
10 Caution children about dropping or pushing objects into the TV set
through cabinet openings. Some internal parts carry hazardous
voltages and contact can result in a fire or electrical shock.
11 Unplug the TV set from the wall outlet before cleaning. Do
not use liquid or an aerosol cleaner.
12 Never add accessories to a TV set that has not been designed for
this purpose. Such additions may result in a hazard.
13 For added protection of the TV set during a lightning storm or
when the TV set is to be left unattended for an extended peri-
od of time, unplug it from the wall outlet and disconnect the
antenna. This will prevent damage to product due to lightning
storms or power line surges.
14 A TV set and cart combination should be moved with care.
Quick stops, excessive force, and uneven surfaces may cause
the TV set and cart combination to overturn.
SERVICE
15 Unplug this TV set from the wall outlet and refer servicing to
qualified service personnel under the following conditions:
A. When the power cord or plug is damaged or frayed.
B. If liquid has been spilled into the TV set.
C. If the TV set has been exposed to rain or water.
D. If the TV set does not operate normally by following the
operating instructions. Adjust only those controls that are
covered in the operating instructions as improper adjust-
ment of other controls may result in damage and will often
require extensive work by a qualified technician to restore
the TV set to normal operation.
E. If the TV set has been dropped or damaged in any way.
F. When the TV set exhibits a distinct change in perform-
ance — this indicates a need for service.
16 Do not attempt to service this TV set yourself as opening or
removing covers may expose you to dangerous voltage or
other hazards. Refer all servicing to qualified service person-
nel.
17 When replacement parts are required, have the service tech-
nician verify in writing that the replacement parts he uses
have the same safety characteristics as the original parts.
Use of manufacturer’s specified replacement parts can pre-
vent fire, shock, or other hazards.
18 Upon completion of any service or repairs to this TV set,
please ask the service technician to perform the safety check
described in the manufacturer’s service literature.
19 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 pro-
vides 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.
