1. Precautions and Safety Notices

Prior to using this manual, please ensure that you have carefully followed all the procedures outlined in the

user manual for this product.

• Read all of these instructions.

• Save these instructions for later use.

• Follow all warnings and instructions marked on the product.

• Do not use this product near water.

• This display should be installed on a solid horizontal base.

• When cleaning, use only a neutral detergent cleaner with a soft damp cloth. Do not spray with liquid or

aerosol cleaners.

• Do not expose this display to direct sunlight or heat. Hot air may cause damage to the cabinet and other

parts.

• Adequate ventilation must be maintained to ensure reliable and continued operation and to protect the

display from overheating. Do not block ventilation slots and openings with objects or install the display in

a place where ventilation may be hindered.

• Do not install this display near a motor or transformer where strong magnetism is generated. Images on the

display will become distorted and the color irregular.

• Do not allow metal pieces or objects of any kind fall into the display from ventilation holes.

Slots and openings in the cabinet and the back or bottom are provided for ventilation, to ensure reliable

operation of the product and to protect it from overheating, those openings must not be blocked or covered.

The openings should never be blocked by placing the product on a bed, sofa, rug, or other similar surface.

This product should never be placed near or over a radiator or heat register. This product should not be placed

in a built-in installation unless proper ventilation is provided.
