Electrical Code, ANSI/NFPA 70
Lightning
For added protection for this TV receiver 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 to the
receiver due to lightning and power-line surges.
Service
Damage Requiring Service
Unplug the unit from the wall outlet and refer servicing to qualified service
personnel under the following conditions:
s When the power cord or plug is damaged
or frayed.
s If liquid has been spilled into the unit.
s If the unit has been exposed to rain or water.
s If the unit has been subject to excessive shock
by being dropped, or the cabinet has been
damaged.
s If the unit does not operate normally when
following the operating instructions. Adjust only
those controls that are specified in the operating
instructions. Improper adjustment of other
controls may result in damage and will often
require extensive work by a qualified technician
to restore the unit to normal operation.
s When the unit exhibits a distinct change in
performance, it indicates a need for service.
Servicing
Do not attempt to service the unit yourself since opening
the cabinet 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 certifies in writing that he/she has used
replacement parts specified by the manufacturer that
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 unit,
ask the service technician to perform routine safety
checks (as specified by the manufacturer) to determine
that the unit is in safe operating condition, and to so
certify. When the unit 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 unit.
