slots or openings. Never spill any kind of liquid on the television receiver.
!
Caution
If the television is to be built into a compartment or similarly enclosed, the minimum distances must be maintained. Heat build-up can reduce the service life of your television, and can also be dangerous.
!
Caution
Never stand on, lean on, push suddenly the product or its stand. You should pay special attention to children to children.
!
Caution
Do not place the main unit on an unstable cart stand, shelf or table. Serious injury to an individual, and damage to the television, may result if it should fall.
!
When the product is not used for an extended period of time, it
Caution
is advisable to disconnect the AC power cord from the AC
outlet.
!
Avoid exposing the main unit to direct sunlight and other source of the heat. Do not stand the television receiver directly on other produces which give off heat. E. g. video cassette players,Audio amplifiers. Do not block the ventilation holes in the back cover. Ventilation is essential to prevent failure of electrical component. Do not squash power supply cord under the main unit.
