Antennas
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.
Section 810 of the National Electrical Code (NEC) in
USA and Section 54 of the Canadian Electrical Code in
Canada provides information with respect to proper
grounding of the mast and supporting structure,
grounding of the lead-in wire to an antenna discharge
unit, size of grounding conductors, location of antenna
discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
Antenna Grounding According to the NEC
Refer to section 54-300 of Canadian Electrical Code for
Antenna Grounding.
Cleaning
❑
Clean the cabinet of the TV with a
dry soft cloth. To remove dust from
the screen, wipe it gently with a soft
cloth. Stubborn stains may be
removed with a cloth slightly
dampened with solution of mild soap and warm
water. Never use strong solvents such as thinner or
benzine for cleaning. If the picture becomes dark
after using the TV for a long period of time, it may
be necessary to clean the inside of the TV. Consult
qualified service personnel.
❑
Unplug the AC power cord when cleaning this unit.
Cleaning this unit with a plugged AC power cord
may result in electric shock.
On Contamination on the Screen Surface
The screen surface has a special coating to reduce
reflections. To prevent screen damage, clean the screen as
follows:
❑
Clean the screen with a soft cloth.
❑
To remove hard contamination, use a cloth
moistened with a solution of mild detergent and
water. Do not spray cleaning solution directly onto
the TV. It should only be sprayed to moisten the
cleaning cloth.
❑
Do not use any type of abrasive pad, alkaline
cleaner, acid cleaner, scouring powder, chemical
cloth, or solvent such as alcohol, benzene or thinner,
as these may scratch the screen's coating.
Service
Damage Requiring Service
Do not attempt to service the set by yourself
since opening the cabinet may expose you to
dangerous voltage or other hazards.
Unplug the set from the wall outlet and refer
servicing to qualified service personnel.
Replacement Parts
When replacement parts are required, be sure the service
technician certifies in writing that he 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.
See “Replacing the Lamp” on page 76.
