CLEANING
Cleaning the AC power plug Unplug the AC power plug and clean it regularly. If the plug is covered with dust and gathers moisture, its insulation may deteriorate and result in a fire.
Cleaning the screen surface/ cabinet of the TV set
When cleaning this TV, unplug the AC power 
cord. If not, it may result in electric shock. Use
a dry soft cloth to clean the cabinet of the TV. To remove dust near the screen, wipe it gently with a soft cloth. Stubborn stains
may be removed with a cloth slightly dampened with a solution of mild soap and warm water. Never use strong solvents such as thinner or benzine for cleaning. If using a chemically pretreated cloth, please follow the instruction provided on the package. The ventilation holes can accumulate dust over time.
To ensure proper ventilation, we recommend you to remove the dust periodically (once a month) using a vacuum cleaner, while the LED TV is powered off.
MAGNETIC INFLUENCE
This TV contains a strong magnet in the speaker unit that generates a magnetic field. Keep any items susceptible to magnetic fields away from the speaker.

If you hear snapping or popping sound comes from
the TV continuously or frequently while the TV is operating,
unplug the TV and consult your dealer or service
