(continued)
Cleaning-
Unplug the TV set from the wall outlet before cleaning or polishing it. Do not use liquid cleaners or aerosol cleaners.
Use a dry cloth for cleaning the exterior of the TV set.
Attachments-
Do not use attachments not recommended by the product manufacturer as they may cause hazards or electric
shock.
If a snapping or popping sound from a TV set is heard continuously or frequently while the TV set is operated, unplug the TV
set and consult your dealer or service technician. It is normal for some TV sets to make occasional snapping or popping
sounds, particularly when being turned on or off.
Damage Requiring Service-
Unplug the TV set from the wall outlet and refer servicing to qualified service personnel under the
following conditions:
a. If the power cord or plug is damaged or frayed.
b. If liquid has been spilled or objects have fallen into the TV set.
c. If the TV set has been exposed to rain or water.
d. If the TV set has been subject to excessive shock by being dropped, or the cabinet has been damaged.
e. If the TV set does not operate normally by following the operating instructions. Adjust only those controls that are covered
by the operating instructions as an improper adjustment of other controls may result in damage and will often require
extensive work by a qualified technician to restore the TV set to its normal operation.
f. When the TV set exhibits a distinct change in performance-this indicates a need for service.
Servicing-
Do not attempt to service the TV set yourself as opening or removing covers may expose you to dangerous voltage
or other hazards. Refer all servicing to qualified service personnel.
Replacement Parts-
When replacement parts are required, be sure the service technician has used replacement parts
specified by the manufacturer or have the same characteristics as the original parts. Unauthorized substitutions may result in
fire, electric shock, or other hazards.
Safety Check-
Upon completion of any service or repairs to the TV set, ask the service technician to perform routine safety
checks to determine that the TV set is in proper operating condition.
When the TV set reaches the end of its useful life, improper disposal could result in a picture tube implosion. Ask a qualified
service technician to dispose of the TV set.
ANTENNA
Outdoor Antenna Grounding-if an outdoor antenna is installed, follow the precautions below.
An outdoor antenna system should not be located in the vicinity of overhead power lines or other electric light or power circuits,
or where it can come in contact with such power lines or circuits.
WHEN INSTALLING AN OUTDOOR ANTENNA SYSTEM, EXTREME CARE SHOULD BE TAKEN TO KEEP FROM
CONTACTING SUCH POWER LINES OR CIRCUITS AS CONTACT WITH THEM IS ALMOST INVARIABLY FATAL
Be sure the antenna system is grounded so as to provide some protection against voltage surges and built-up static charges.
