Before unpacking the LCD Monitor, prepare a suitable workspace for your Monitor and computer.
You need a stable and clean surface near a wall power outlet. Make sure that LCD Monitor has
enough space around it for sufficient airflow. Though the LCD Monitor uses very little power, some
ventilation is needed to ensure that the Monitor does not become too hot.
After you unpack the LCD Monitor, make sure that the following items were included in the box:
* LCD Monitor * User's Manual
* 1.5M Monitor-to-PC signal Cable * AC Adapter
