SAFETY TIPS
PROTECTION AND LOCATION OF YOUR SET
16-1 If an outside antenna is connected to the televi-
sion 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, NFPA No. 70-1975,
provides information with respect to proper
grounding of the mast and supporting structure,

Note to CATV system installer:
(Only for the television set with CATV reception)
This reminder is provided to call the CA'iV sys-
tem installer's attention to Article 820-40 of the
NEC that provides guidelines for proper ground-
ing and, in particular, specifies that the cable
ground shall be connected to the grounding sys-
tem of the building, as close to the point of cable
entry as practical.
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.
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 itfrom the
wall outlet and disconnect the antenna. This will
prevent damage due to lightning and power-line
surges.
OPERATION OF YOUR SET
19 This television set should be operated only from
the type of power source indicated on the marking
label. If you are not sure of the type of power
supply at your home, consult your television dealer
or local power company. For television sets
designed to operate from battery power, refer to
the operating instructions.
2O
If the television set does not operate normally by
following the operating instructions, unplug this
television set from the wall outlet and refer servic-
ing to qualified service personnel. Adjust only
those controls that are covered in the operating
instructions as improper adjustment of other con-
trols may result in damage and will often require
extensive work by a qualified technician to re-
store the television set to normal operation.
When going on a holiday: If your television set is
to remain unused for a period of time, turn the
television set "off' and unplug it from the wall
outlet.

Whenever the television set is damaged or fails,
or a distinct change in performance indicates a
need for service, unplug the set and have it
checked by a professional service technician.
It is normal for some TV sets to make occasional
snapping or popping sounds, particularly when
being turned on or off. If the snapping or popping
is continuous or frequent, unplug the set and
consult your dealer or sen,ice technician.
FOR SERVICING AND MODIFICATION

parts specified by the manufacturer that have the
same characteristics as the original part. Unau-
thorized substitutions may result in fire, electric
shock, or other hazards.
