WARNING
To prevent fire or shock hazard, do not expose the set
to rain or moisture.
Dangerously high voltages are present inside the set.
Do not open the cabinet. Refer servicing to qualified
personnel only.

PRECAUTIONS
USE
• Operate only on 120 V ac.
• This set is equipped with a polarized ac power cord plug (one blade of the plug
is wider than the other), which will fit into the power outlet only one way. Should
you be unable to insert the plug fully into the outlet, try reversing the plug. If the
plug still fails to fit, contact your dealer for assistance. Do not defeat the safety
purpose of the polarized plug.
• Should any liquid or solid object fall into the cabinet, unplug the set and have it
checked by qualified personnel before operating it any further.
• Unplug the set from the wall outlet or set the MASTER button to OFF if it is not
to be used for several days.
• To disconnect the cord, pull it out by the plug. Never pull the cord itself.
INSTALLATION
• Allow adequate air circulation to prevent internal heat build-up. Do not place
the set on surfaces (rugs, blankets, etc.) or near materials (curtains, draperies)
that may block the ventilation holes.
• Do not install the set in a location near heat sources such as radiators or air
ducts, or in a place subject to direct sunlight, excessive dust, mechanical vibra¬
tion or shock.
• Save the original shipping carton and packing material; they will come in han¬
dy if you ever have to ship your set. For maximum protection, repack your set as it
was originally packed at the factory.
• To keep the set looking brand-new, periodically clean it with a soft cloth. Stub¬
born stains may be removed with a cloth lightly dampened with a mild detergent
solution. Never use strong solvents such as thinner or benzine, or abrasive
cleansers since these will damage the cabinet. As a safety precaution, unplug the
set before cleaning it.
For detailed safety precautions, see the leaflet “IMPORTANT
SAFEGUARDS” included with this manual in the vinyl bag.

CABLE TV OPERATION (PANEL OPERATION)
In CATV (cable television) systems, programs are brought into the
home on the mid-band channels and the super-band channels.
With the NORMAL/CATV selector set to CATV, this TV receives mid¬
band channels A-2, A-1, A through I and super-band channels J
through W.
Channel A 2 can be tuned in by selecting number 00 on this TV,
channel A-1 by selecting number 01, channel A by selecting
number 14, and so on, as follows:
Most CATV systems use letters to designate channels but some
use numbers. To tune in a numbered channel, select the same
number on the TV.
Consult your local cable TV company or your nearest Sony dealer
to find out which of these channels are receivable and which type
of cable system is used in your area. (Pay cable TV systems use
scrambled or encoded signals and require special converters.)

memory, or vice versa.
If either the UHF channel or the CATV channel of the same number
is to be kept in the memory, do not erase the number.

EXTERNAL ANTENNA/CABLE CONNECTION
If your local signal is strong, an indoor antenna may be sufficient to
obtain a clear picture.
The use of an external antenna is recommended especially in dif¬
ficult reception areas (inside steel-frame buildings, in mountainous
areas, or at great distances from the transmitter).
VHF antenna
Pull out the antenna connector from the VHF antenna terminal,
thus disconnecting the VHF telescopic dipole antenna. Use the
antenna connector for 300-ohm ribbon type lead-in connection.
When the cable is a
300-ohm ribbon type
lead-in (flat)
UHF antenna
Loosen the screws on the UHF antenna terminals, and pull out the
lugs of the UHF loop antenna.
Connect the wire and
tighten the screws.
Combination VHF/UHF antenna
Most combination antennas already have a signal splitter. If you
need a splitter or a complete antenna system, see your Sony dealer
or a qualified technician.
CATV cable
Connect the CATV coaxial cable to the VHF antenna terminal. We
recommend that you consult your cable TV company to make sure
that the cable is properly connected.
