receptacles marked between 100-240V AC, Min. 5A.

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 re or electric
shock. Never spill liquids on the monitor.
Do not place the front of the product on the oor.
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 re 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

Cleaning
Clean the cabinet regularly with a water-dampened, soft cloth.
When cleaning use a soft cotton or microber 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.

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.

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.
