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 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.

Safety Instructions For Television Receivers

1. Read and apply the operating instructions provided with your television receiver.

2. Read all of the instructions given here and retain them for later use.

3. Unplug this television receiver from the wall outlet betore cleaning. Do not use liquid or aerosol cleaners. Use a damp
cloth for cleaning.

4. Do not use attachments not recommended by the television receiver manufacturer _.s they may cause hazards.

5. Do not use this television receiver near water. For example: Avoid placing it near a bathtub, washbowl, kitchen sink, or

6A. An appliance and cart combination should be moved with care. Quick stops, excessive force, and I_

uneven surfaces may cause the appliance and cart combination to overturn.

7. Slots and openings in the cabinet and the back or bottom are provided for ventilation, and to insure
reliable operation of the television receiver and to protect it from ow;rheating. These openings must not be blocked or

covered. The openings should never be blocked by placing the television receiver on a bed, sofa, rug or other similar

surface. This television receiver should never be placed near or over a radiator or heat register. This television receiver
should not be placed in a built-in installation such as a bookcase unless proper wantilation is provided.

8. Operate only from the type of power source indicated on the marking label. If ycu are not sure of the type of power

suppfied to your home consult your television dealer or local power company. For television receivers designed to

14. If an outside antenna is connected to the television equipment, be sure the antenna system is grounded so as to provide
some protection against voltage surges and built up static charges. In the U.S. Section 810 of the National Electrical Code

and in Canada Part 1 of the Canadian Electrical Code provides informatior ,with respect to proper grounding of the mast
and suppo_ling 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.

15. For added protection for this television receiver during a lightning storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage to the receiver due to

lightning and power-line surges.

16. 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.

17. Unplug this television receiver 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 television receiver.
c. If the television receiver has been exposed to rain or water.
d. If the television receiver does not operate normally by following the operating instructions. Adjust only those controls

that are covered by the operating instructions as improper adjustment of other control.'; may result in damage and will

often require extensive work by a qualified technician to restore the television receiver to normal operation.
e. If the television receiver has been dropped or the cabinet has been damaged.
f. When the television receiver exhibits a distinct change in performance - this indicates a need for servioe.

18. Do not attempt to service this television receiver yourself as opening or removing covers may expose you to dangerous
voltage or other hazards. Refer all servicing to qualified service personnel.

19. When replacement parts are required, be sure the service technician has used replacement parts specified by the
manufacturer that have the same characteristics as the original part. Unauthorized substitutions may result in fire, electric

shock, or other hazards.

20. Upon completion of any service or repairs to this television receiver, ask the service technic an to perform routine safety
checks to determine that the television is in safe operating condition.

21. WARNING:: To prevent fire or shock hazard, do not expose this appliance to rain or moisture.

22. CAUTION: TO PREVENT ELECTRIC SHOCK DO NOT USE THIS (POLARIZED) PLUG VVITH AN EXTENSION CORD,

RECEPTACLE OR OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSER-[ED TO PREVENT BLADE
EXPOSURE.

NOTE: This equipment is designed to operate in the U.S.A., Canada and other countries where the broadcasting system and

AC house current is exactly the same as in the U.S.A. and Canada.

Important Information Regarding Use of Video Games, Computers, Teletext or Other Fixed Image Displays.

The extended use of fixed image program material can cause a permanent "shadow image" on the picture tube. This

background image is viewable on normal programs in the form of a stationary fixed image. This type of irreversible picture tube
deterioration can be limited by observing the following steps:
A. Reduce the brightness/contrast setting to a minimum viewing level.

B. Do not display the fixed image for extended periods of time.
C. Turn the power off when not in actual use.

NOTE: The marking or retained image on the picture tube resulting from fixed image use is nol an operating defect and as

such is not covered by Warranty. This product is not designed to display fixed image patlerns for extended periods of
time.

Care and Cleaning

Picture Tube (Turn set off)

Use a mild soap solution or window cleaner and a clean cloth. DO NOT USF ABRASIVE CLEANERS. Avoid excessive
moisture and wipe dry.

Plastic Cabinets

Wipe the cabinet with a soft cloth dampened with water or a mild detergent solution and wi!ce dry with a soft clean cloth.
Avoid excessive moisture. Do not use benzene, thinners or other petroleum based cleaners.

Wood Cabinets

When dusting or polishing the cabinet, use a clean soft cloth and stroke straight with the grain. An occasional coat of
furniture polish will help preserve the finish. Do not use benzene, thinners or other petroleum based cleaners. Do not

place objects made of plastic or rubber directly on top of the cabinet. A chemical reaction could result causing permanent
marring of the finish.

Remote Control Transmitter

Do not use benzene, thinners or other petroleum based cleaners to clean the, Remote Control Transmitter. To c!lean, wipe
with a soft cloth slightly moistened with a mild detergent and then wipe d_ with a soft clean cloth.

Installation

Location

Locate for comfortable viewing. Avoid placing where sunlight or other bright light (including reflections) will fall on the
screen.

Adecluate ventilation is essential to prevent internal component failure. Keep away from areaLs of excessive heat or

moisture. Do not position magnetic equipment (motors, fans, other speakers, etc.) nearby.

Optional External Equipment Connections

The Video/Audio connections between components can be made with shielded video and audio cables. For best perfor-

mance, video cables should utilize 75 ohm coaxial shielded wire. Cables are available from you" dealer or electronic

supply house.

Before you purchase any cables, be sure you know what type of output and input connectors your various components
require. Also determine the length of cable you'll need.

AC Power Supply Cord

Insert (Polarized) plug into 120 volts 60mz standard AC outlet. Do not defeat the safety
purpose of the polarized plug.

CAUTION: TO PREVENT ELECTRIC SHOCK DO NOT USE THIS (POLARIZED) PLUG

WITH AN EXTENSION CORD, RECEPTACLE OR OTHER OUTLET UNLESS THE BLADE

CAN BE FULLY INSERTED TO PREVENT BLADE EXPOSURE
