Safety and Maintenance Guidelines
Important Safety Information
A power cord is included with the monitor. If another cord is used, use only a power source and connection appropriate for this monitor. For information on the correct power cord set to use with the monitor, refer to the "Connecting the Power Cable" section in Setting Up the Monitor WARNING!To reduce the risk of electric shock or damage to the equipment: · Do not disable the power cord grounding feature. · Plug the power cord in a grounded (earthed) outlet that is easily accessible at all times. · Disconnect power from the product by unplugging the power cord from the electrical outlet. Arrange them so that no one may accidentally step on or trip over them. When unplugging from the electrical outlet, grasp the cord by the plug. To reduce the risk of serious injury, read the Safety and Comfort Guide. It describes proper workstation, setup, posture, and health and work habits for computer users, and provides important electrical and mechanical safety information. This guide is located on the Web at http://www. hp. com/ergo and/or on the documentation CD, if one is included with the monitor. CAUTION: For the protection of the monitor, as well as the computer, connect all power cords for the computer and its peripheral devices (such as a monitor, printer, scanner) to some form of surge protection device such as a power strip or Uninterruptible Power Supply (UPS). Not all power strips provide surge protection; the power strips must be specifically labeled as having this ability. Use a power strip whose manufacturer offers a Damage Replacement Policy so you can replace the equipment, if surge protection fails. Use the appropriate and correctly sized furniture designed to properly support your HP LCD monitor. LCD monitors that are inappropriately situated on dressers, bookcases, shelves, desks, speakers, chests, or carts may fall over and cause personal injury. Care should be taken to route all cords and cables connected to the LCD monitor so that they can not be pulled, grabbed, or tripped over.
