Small accessories
Keep small accessories out of children’s reach.
Antennas
If an outdoor antenna is installed, follow the precautions below. Keep
an outdoor antenna away from high-voltage feeder lines or other
streetlamp or power circuits or in places that may come in contact with
power lines or circuits of such kind.
When installing an outdoor antenna system, do not touch these power
lines or circuits. The consequence may be fatal.
The antenna system must be grounded to prevent surges or built-up
static charges.
Antenna grounding according to the National Electrical Code
Caution for CATV system providers: CATV system providers shall
follow the NEC Section 820-40 where the proper grounding principles
are specified; particularly that cables must be grounded to the
building’s grounding system and kept as close as possible to the
antenna lead-in point.
Batteries
y
Do not dispose of batteries in the fire.
y
Dot not short-circuit, disassemble or overheat batteries.
y
Incorrect replacement of batteries may cause the risk of battery
explosion. Always replace with batteries of the same or equivalent
type.
Disposal of used batteries
Dispose of used batteries according to local laws and regulations to
protect our environment.
Cleaning
Cleaning the AC power plug
Unplug the AC power cord to clean the plug regularly. If too much dust
is deposited on the plug, it will absorb moisture, which reduces
insulation performance and may lead to a fire.
Clean the TV screen and enclosure
y
Unplug the AC power cord from the outlet to prevent electric shock
during the cleaning process.
y
Clean the TV enclosure with a soft dry cloth. Wipe off the dust on
the screen gently with a soft cloth. Remove stubborn stains with a
soft cloth dampened with mild soapy water. Never use strong
solvents, such as thinner or benzene to clean the screen or
enclosure.
y
When cleaning with a chemically pretreated cloth, follow the
instructions on the package .
y
Dust may accumulate at the ventilation vents over time. Therefore,
users are recommended to remove the dust at ventilation vents with
a vacuum cleaner regularly (once a month) to ensure good
ventilation.
Magnetic interference
The speakers equipped on this TV contain a strong magnet which
generates a magnetic field. Keep objects that may interfere with
magnetic fields away from the TV speakers.
Sound
If a snapping or popping sound is often heard from the TV when in use,
disconnect the power supply of the TV and consult your dealer or
service personnel. It is normal that snapping or popping sounds are
heard occasionally from the TV, particularly when turning the power on
and off.
