IMPORTANT SAFEGUARDS  
16-2 Note to CATV system installer: (Only for the television set with CATV reception) 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.  
IMPORTANT SAFEGUARDS  
17 An outside antenna system should not be located in the vicinity of overhead power  
lines or other electrical lights 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.  
18 For added protection for this television set 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 due to lightning and power-line  
surges.

BEFORE OPERATING YOUR TV SET  
BEFORE OPERATING YOUR TV SET  
INSTALLATION  
ANTENNA  
Unless your TV set is connected to a cable TV system or to a centralized antenna  
system, a good outdoor color TV antenna is recommended for the best performance.  
However, if you are located in an exceptionally good signal area that is free from  
interference and multiple image ghosts, the indoor antenna may be sufficient.  
LOCATION  
Select an area where sunlight or bright indoor illumination will not fall directly on the  
picture screen. Also, be sure that the location selected allows a free flow of air to and  
from the perforated back cover of the TV set.  
To prevent damaging the TV, do not leave the set in a place where the temperature  
becomes too hot. For example, exposed to direct sunlight or near a heating device, etc.  
VIEWING  
This TV set may be viewed from any desired distance. Most viewers prefer a distance of  
three to six feet or more, depending on screen size, for maximum eye comfort.  
NOTE: Model Number and serial number are indicated on the back cover of the TV set.  
BEFORE OPERATING YOUR TV SET  
ANTENNA CONNECTIONS  
These sets are equipped with one VHF/UHF terminal can be used for normal TV, cable  
TV (CATV), a TV game, etc.  
1. VHF (75 ohm) antenna/CATV  
When using a 75 ohm coaxial cable system, disconnect the VHF adaptor from the VHF  
75 ohm receptacle and connect the outdoor antenna or CATV cable to a VHF 75 ohm  
receptacle  
2. VHF (300-Ohm) antenna/UHF antenna  
When using a 300-Ohm twin lead from an outdoor antenna, disconnect the (VHF or  
UHF) indoor antenna leads from screws of the (VHF or UHF) adapter, and connect  
outdoor (VHF or UHF) antenna leads to these screws of a (VHF or UHF) adapter.  
3. When both VHF and UHF antennas are connected  
Attach an optional ANT. MIXER to the TV antenna terminal, and connect the cables to  
the ANT. MIXER.  
Notes  
1. If an outdoor antenna/CATV is to be used, disconnect the indoor antenna. Do not leave  
both the indoor and outdoor antennas/ CATV connected at the same time, since ghosting  
and poor reception may result.  
2. Consult your dealer or service store for the ANT. MIXER of VHF adaptor.  
3. The special converter (decoder) will be supplied by the cable company.  
HOOK-UP CABLES AND CONNECTORS  
HOOK-UP CABLES AND CONNECTORS  
Most video/audio connections between components can be made with shielded video  
and audio cables that have phono connectors. For best performance, video cables  
should use 75-Ohm coaxial shielded wire. Cables can be purchased from most stores  
that sell audio/video products. Below are illustrations and names of common  
connectors.  
Before purchasing any cables, be sure of the output and input connector types required  
by the various components. Also make sure the cables are the correct length.

USING THE GENIUS REMOTE TO LEARN ADDITIONAL  
FUNCTIONS (31GX31B ONLY)  
• The Genius Remote is equipped with a learning function which allows it to learn  
additional infrared control codes. This remote will not only control the television, a VCR,  
and a cable box, but also other electronic equipment which uses an infrared remote  
transmitter, by learning the transmitter's codes.  
• Only infrared remote control codes can be stored in memory.  
Before starting the memory operation  
• Since the infrared signals sent from the remote transmitter may be reflected by a wall,  
door, etc., even if the transmitter is not pointed directly at the device, it may operate.  
When storing the remote control codes of another device, turn OFF the power of the  
device (VCR, Cable Converter, etc.)  
If you do not do this, the device may work unexpectedly. The power could be turned  
ON, an important tape could be erased, the volume could increase too much, etc..

TROUBLESHOOTING  
TROUBLESHOOTING  
RECEPTION PROBLEMS (EXTERNAL TO THE TV)  
IGNITION NOISE:  
Black spots or horizontal streaks may appear, picture may flutter or drift. Usually  
caused by interference from automobile ignition systems, neon lamps, electrical drills  
and other electrical appliances.  
GHOSTS:  
Ghosts are caused by the television signal following two paths. One is the direct path  
and the other is reflected from tall buildings, hills or some other objects. Changing the  
direction or position of the antenna may improve reception. Ghosting may also be  
caused by defects in the antenna system such as unshielded leads or connecting  
several sets to the same antenna without using multiple antenna couplers.  
SNOW:  
If your receiver is located in the fringe area of a television station where the signal is  
weak, your picture may be marred by the appearance of small dots. When the signal is  
extremely weak, it may be necessary to install a special antenna to improve the picture.  
RADIO FREQUENCY INTERFERENCE:  
The interference produces moving ripples or diagonal streaks, and in some cases,  
causes loss of contrast in the picture.
