Safety
National Conventions
The following subsections describe national conventions used in this document. Notes, Cautions, and Warnings Throughout this guide, blocks of text may be accompanied by an icon and printed in bold type or in italic type. These blocks are notes, cautions, and warnings, and they are used as follows: NOTE: A NOTE indicates important information that helps you make better use of your computer system. CAUTION: A CAUTION indicates either potential damage to hardware or loss of data and tells you how to avoid the problem. WARNING: A WARNING indicates the potential for bodily harm and tells you how to avoid the problem. Some warnings may appear in alternate formats and may be unaccompanied by an icon. In such cases, the specific presentation of the warning is mandated by regulatory authority.
1
Power
The monitor should be operated only from the type of power source indicated on the label. If you are not sure of the type of power supplied to your home, consult your dealer or local power company.
The monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin. This plug will fit only into a grounded power outlet as a safety feature. If your outlet does not accommodate the three-wire plug, have an electrician install the correct outlet, or use an adapter to ground the appliance safely. Do not defeat the safety purpose of the grounded plug.
Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will protect the monitor from damage due to power surges.
Do not overload power strips and extension cords. Overloading can result in fire or electric shock. To ensure satisfactory operation, use the monitor only with UL listed computers which have appropriate configured receptacles marked between 100-240V AC, Min. 5A. The wall socket shall be installed near the equipment and shall be easily accessible.
2
Installation
Do not place the monitor on an unstable cart, stand, tripod, bracket, or table. If the monitor falls, it can injure a person and cause serious damage to this product. Use only a cart, stand, tripod, bracket, or table recommended by the manufacturer or sold with this product. Follow the manufacturer’s instructions when installing the product and use mounting accessories recommended by the manufacturer. A product and cart combination should be moved with care.
Never push any object into the slot on the monitor cabinet. It could damage circuit parts causing a fire or electric shock. Never spill liquids on the monitor.
Do not place the front of the product on the floor.
If you mount the monitor on a wall or shelf, use a mounting kit approved by the manufacturer and follow the kit instructions.
Leave some space around the monitor as shown below. Otherwise, air-circulation may be inadequate hence overheating may cause a fire or damage to the monitor.
To avoid potential damage, for example the panel peeling from the bezel, ensure that the monitor does not tilt downward by more than -5 degrees. If the -5 degree downward tilt angle maximum is exceeded, the monitor damage will not be covered under warranty.
See below the recommended ventilation areas around the monitor when the monitor is installed on the wall or on the stand:
Installed with stand
12 inches 30cm
4 inches 10cm
4 inches 10cm
Leave at least this much space around the set
4 inches 10cm

Cleaning
Clean the cabinet regularly with a water-dampened, soft cloth. When cleaning use a soft cotton or microfiber cloth. The cloth should be damp and almost dry, do not allow liquid into the case. Please disconnect the power cord before cleaning the product.
4
Other
If the product is emitting a strange smell, sound or smoke, disconnect the power plug IMMEDIATELY and contact a Service Center.
Make sure that the ventilating openings are not blocked by a table or curtain. Do not engage the LCD monitor in severe vibration or high impact conditions during operation. Do not knock or drop the monitor during operation or transportation. The power cords shall be safety approved. For Germany, it shall be H03VV-F, 3G, 0.75 mm2, or better. For other countries, the suitable types shall be used accordingly. Excessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of the equalizer to maximum increases the earphones and headphones output voltage and therefore the sound pressure level.

AOC Monitors Panel Pixel Defect Policy
AOC strives to deliver the highest quality products. We use some of the industry’s most advanced manufacturing processes and practice stringent quality control. However, pixel or sub pixel defects on the Monitor panels used in the monitors are sometimes unavoidable. No manufacturer can guarantee that all panels will be free from pixel defects, but AOC guarantees that any monitor with an unacceptable number of defects will be repaired or replaced under warranty. This notice explains the different types of pixel defects and defines acceptable defect levels for each type. In order to qualify for repair or replacement under warranty, the number of pixel defects on a Monitor panel must exceed these acceptable levels. For example, no more than 0.0004% of the sub pixels on a monitor may be defective. Furthermore, AOC sets even higher quality standards for certain types or combinations of pixel defects that are more noticeable than others. This policy is valid worldwide.

pixel
Pixels and Sub pixels A pixel, or picture element, is composed of three sub pixels in the primary colors of red, green and blue. Many pixels together form an image. When all sub pixels of a pixel are lit, the three colored sub pixels together appear as a single white pixel. When all are dark, the three colored sub pixels together appear as a single black pixel. Other combinations of lit and dark sub pixels appear as single pixels of other colors. Types of Pixel Defects Pixel and sub pixel defects appear on the screen in different ways. There are two categories of pixel defects and several types of sub pixel defects within each category. Bright Dot Defects Bright dot defects appear as pixels or sub pixels that are always lit or ‘on’. That is, a bright dot is a sub-pixel that stands out on the screen when the monitor displays a dark pattern. There are the types of bright dot defects.
One lit red, green or blue sub pixel.
Two adjacent lit sub pixels: – Red + Blue = Purple – Red + Green = Yellow – Green + Blue = Cyan (Light Blue)
29
Three adjacent lit sub pixels (one white pixel). Note A red or blue bright dot must be more than 50 percent brighter than neighboring dots while a green bright dot is 30 percent brighter than neighboring dots.
Black Dot Defects
Black dot defects appear as pixels or sub pixels that are always dark or `off’. That is, a dark dot is a sub-pixel that stands out on the screen when the monitor displays a light pattern. These are the types of black dot defects.
Proximity of Pixel Defects
Because pixel and sub pixels defects of the same type that are near to one another may be more noticeable, AOC also specifies tolerances for the proximity of pixel defects.
Pixel Defect Tolerances
In order to qualify for repair or replacement due to pixel defects during the warranty period, a Monitor panel in a AOC panel monitor must have pixel or sub pixel defects exceeding the tolerances listed in the web manual.
BRIGHT DOT DEFECTS 1 lit subpixel 2 adjacent lit subpixels 3 adjacent lit subpixels (one white pixel) Distance between two bright dot defects* Total bright dot defects of all types BLACK DOT DEFECTS 1 dark subpixel
ACCEPTABLE LEVEL 2 1 0 >=15mm 2 ACCEPTABLE LEVEL 5 or fewer
2 adjacent dark subpixels
2 or fewer
3 adjacent dark subpixels Distance between two black dot defects* Total black dot defects of all types
0 15mm 5 or fewer
TOTAL DOT DEFECTS
