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.

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.
