not work
Maintenance
Early malfunctions can be prevented. Careful and regular cleaning can extend the amount
of time you will have your new TV. Be sure to turn the power off and unplug the power
cord before you begin any cleaning.
Cleaning the screen
1. Here's a great way to keep the dust off your screen for a while. Wet a soft cloth in a
mixture of lukewarm water and a little fabric softener or dish washing detergent. Wring the
cloth until it's almost dry, and then used it to wipe the screen.
2. Make sure the excess water is off the screen, and then let it air-dry before you turn on
your TV.
Cleaning the cabinet
To remove dirt or dust, wipe the cabinet with a soft, dry, lint-free cloth. Please be sure not
to use a wet cloth.
Extended Absence
If you expect to leave your TV dormant for a long time (such as a vacation), it's a
good idea to unplug the power cord to protect against possible damage from
lightning or power surges.
Disposal of old electrical appliances
The European directive 2012/19/EU on Waste Electrical and Electronic
Equipment (WEEE), requires that old household electrical appliances must not
be disposed of in the normal unsorted municipal waste stream. Old appliances
must be collected separately in order to optimize the recovery and recycling of
the materials they contain, and reduce the impact on human health and the
environment.
The crossed out "wheeled bin" symbol on the product reminds you of your
obligation, that when you dispose of the appliance, it must be separately
collected.
Consumers should contact their local authority or retailer for information
concerning the correct disposal of their old appliance.
