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 * 1.5M Stereo Jack Audio Cable * 1.8M Power Cord

If you find that any of these items is missing or appears damaged, contact your dealer immediately.
