7. Ventilation - The vents and other openings in the cabinet are designed to let hot air escape 
from the display. Do not cover or block these vents and openings since insufficient 
ventilation can cause overheating and/or shorten the life of the product. Do not place the 
display on a bed, sofa, rug or other similar surface, since they can block ventilation openings. 
This display is not designed for built-in installation; do not place the product in an enclosed 
place such as a bookcase or rack, unless proper ventilation is provided or the manufacturers 
instructions are followed.
8. Heat sources - Keep the product away from heat sources such as radiators, heaters, stoves and 
other heat-generating products (including amplifiers).
9. Power cord protection - Power-supply cords should be routed so that they are not likely to be 
walked on or bitten by small animals. Pay particular attention to cords at doors, plugs, 
receptacles, and the point where they exit from the product.
10. Attachments - Do not use attachments not recommended by the manufacturer. Use of 
improper attachments can result in accidents.
11. Accessories - When the product is used on a trolley, care should be taken to avoid quick 
stops, excessive force, and uneven surfaces that may cause the product and trolley to 
overturn, damaging equipment or causing possible injury to the operator. Do not place this 
product on an unstable trolley, stand, pedestal, bracket, or table. The product may fall, 
causing serious injury to a child or adult and serious damage to the product. The product 
should be mounted according to the manufacturers instructions, and use only with a trolley,

12. Servicing - Do not attempt to service the product yourself. Removing covers can expose you 
to high voltage and other dangerous conditions. Request a qualified service person to 
perform servicing.
13. Replacement parts - In case the product needs replacement parts, make sure that the service 
person uses replacement parts specified by the manufacturer, or those with the same 
characteristics and performance as the original parts. Use of unauthorized parts can result in

product on an unstable base can cause the product to fall, resulting in serious personal 
injuries as well as damage to the product.
20. Careful move - When relocating the product placed on a trolley, it must be moved with the 
utmost care. Sudden stops, excessive force and uneven floor surfaces can cause the product to 
fall from the trolley.
21. Panel protection - The LCD panel used in this product is made of glass.
Therefore, it can break when the display is dropped or hit by other objects. Beware of injuries 
in the event of the LCD glass screen breaking.
22. Pixel defect - The LCD panel is a high technology product, giving you finely detailed 
pictures. Occasionally, a few non-active pixels may appear on the screen as a fixed point of 
blue, green or red. Please note that this does not affect the performance of your product.
23. Installation of an external antenna - If an outside antenna is connected to the television 
equipment, be sure the antenna system is grounded so as to provide some protection against 
voltage surges and built-up static charges.
For added protection for this television equipment during a lightning storm, or when it is left 
unattended and unused for long periods of time, unplug it from the wall outlet and 
disconnect the antenna. This will prevent damage to the equipment due to lightning and 
power-line surges.
An outside antenna system should not be located in the vicinity of overhead power lines or 
other electric light or power circuits, or where it can collide with such power lines or circuits. 
When installing an outside antenna system, extreme care should be taken to keep from 
touching such power lines or circuits, as contact with them might be fatal..
