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 Power Cord Set Requirements on page 40 in Appendix C. WARNING! To reduce the risk of electric shock or damage to the equipment: • Do not disable the power cord grounding feature.
Maintenance Guidelines To enhance the performance and extend the life of the monitor: ● Do not open the monitor cabinet or attempt to service this product yourself. Adjust only those controls that are covered in the operating instructions. If the monitor is not operating properly or has been dropped or damaged, contact an authorized HP dealer, reseller, or service provider. ● Use only a power source and connection appropriate for this monitor, as indicated on the label/ back plate of the monitor.
3 Setting Up the Monitor To set up the monitor, ensure that the power is turned off to the monitor, computer system, and other attached devices, then follow the instructions below. Unfolding the Monitor Pedestal Base 1. Lift the monitor from its box and place it on a flat surface with the display head facing up. 2. Pivot the display head from portrait to landscape position (1). 3. Remove the swivel locking pin (2).
4. Using both hands on the outer edges of the display bezel, pull up gently on the monitor display head (1) to extend the pedestal base (2) to the desired height. CAUTION: Do not touch the surface of the LCD panel. Pressure on the panel may cause nonuniformity of color or disorientation of the liquid crystals. If this occurs the screen will not recover to its normal condition.
Rear Components Figure 3-3 Rear Components Component Function 1 AC Power Connector Connects the AC power cord to the monitor. 2 Audio In (select models) Connects the audio cable to the monitor's internal speakers (select models) 3 USB Downstream Connectors (2) (select models) Connects optional USB devices to the monitor. 4 USB Upstream Connector (select models) Connects the USB hub cable to the monitor's USB hub connector and to a host USB port/hub.
