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.
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 ~, Min. 1.5A
The wall socket shall be installed near the equipment and shall be easily accessible.
5
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.
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.
See below the recommended ventilation areas around the monitor when the monitor is installed on the wall or with

Plug and Play
Plug & Play DDC2B Feature
This monitor is equipped with VESA DDC2B capabilities according to the VESA DDC STANDARD. It allows the
monitor to inform the host system of its identity and, depending on the level of DDC used, communicate additional
information about its display capabilities.
The DDC2B is a bi-directional data channel based on the I2C protocol. The host can request EDID information over
the DDC2B channel.
