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 1of the Canadian 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 to grounding electrodes, and requirements for the grounding electrode.
See Figure.
15. For added protection for this television receiver during alightning 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 sen/icing to qualified sen/ice 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 bythe operating instructions as improperadjustment of other controls may result in damage and will
often require extensive work by aqualified 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 adistinct change in performance -this indicates aneed for service.
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 sen/ice 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 technician 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 WITH ARECEPTACLE OR
OTHER OUTLET UNLESS THE BLADES CAN BE FULLY INSERTED 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, DSS or Other Fixed Image Displays.
The extended use of fixed image program material can cause apermanent "shadow image" on the picture tube. This
background image is viewable on normal programs in the form of astationary fixed image. This type of irreversible picture
tube deterioration can be limited by observing the following steps:
A. Reduce the brightness/contrast setting to aminimum 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 not an operating defect and as
such is not covered by Warranty. This product is not designed to display fixed image patterns for extended periods of
time.

Installation
Receiver Location
This unit is intended to be used with an optional stand or entertainment center. Consult your dealer for available options.
Locate for comfortable viewing. Avoid placing where sunlight or other bright light (including reflections) will fall on the
screen.
Use of some types of fluorescent lighting may reduce remote control transmitter range.
Adequate ventilation is essential to prevent internal component failure. Keep away from areas of excessive heat or
moisture.
To insure optimum color purity 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 your 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.

Remote Control Battery Installation
Batteries: Use two "AA" batteries.
1.Remove the battery compartment cover on back of
the remote,
2. Install the batteries in the battery compartment.
(Polarity (+) or (-) must be correct)
3. Reattach the battery cover.
Helpful Hints:
For frequent Remote Control users, replace
old batteries with Alkaline batteries for longer
life.
Precaution on Battery Use
Incorrect installation can cause battery leakage and
corrosion that will damage the Remote Control
Transmitter.
Observe the Following Precautions:
1.Batteries must be replaced as a pair.
2. Do not combine aused battery with anew one.
3. Do not mix battery types (Example: "Zinc Carbon"
with "Alkaline").
4. Do not attempt to charge, short-circuit, disas-
semble, heat or burn used batteries.
5. Battery replacement is necessary when Remote
Control reacts sporadically or stops operating the
Receiver.
Helpful Hints:
Whenever you remove the batteries to replace
them, you may need to reset the Remote Control
infrared Codes. We recommend that you initially
record the codes in the Infrared Remote Codes for
Specific Components section, prior to setting upthe
remote.

Care and Cleaning
Picture Tube (Turn set off)
Use amild soap solution or window cleaner and aclean cloth. DO NOT USEABRASIVE CLEANERS. Avoid excessive
moisture and wipe dry.
Plastic Cabinets
Wipe the cabinet with asoft cloth dampened with wateror amild detergent solution and wipe dry with asoft clean cloth.
Avoid excessive moisture. Do not use benzene* thinners or other petroleum based cleaners.
Wood Cabinets
When dusting or polishing the cabinet, use aclean 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. Achemical 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 clean,
wipe with asoft cloth slightly moistened with amild detergent and then wipe dry with asoft clean cloth.
