Maintenance Guidelines
To enhance the performance and extend the life of the monitor:
● Do not open the monitor cabinet or attempt to se
rvice this product yourself. Adjust only those
controls that are covered in the operating instru ctions. If the monitor is not operating properly or
has been dropped or damaged, contact an author ized 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.
● Be sure the total ampere rating of the products connected to the outlet does not exceed the current
rating of the electrical outlet, and the total ampere 
rating of the products connected to the cord does
not exceed the rating of the cord. Look on the power label to determine the ampere rating (AMPS
or A) for each device.
● Install the monitor near an outlet that you can easily reach. Disconnect the monitor by grasping the
plug firmly and pulling it fr
om the outlet. Never disconnect the monitor by pulling the cord.
● Turn the monitor off when not in use. You can su
bstantially increase the life expectancy of the
monitor by using a screen saver program and  turning off the monitor when not in use.
● Slots and openings in the cabinet are provided for ventilation. These openings must not be blocked
or covered. Never push objects of any ki
nd into cabinet slots or other openings.
● Do not drop the monitor or place it on an unstable surface.
● Do not allow anything to rest on the 
power cord. Do not walk on the cord.
● Keep the monitor in a well-ventilated area, aw

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.
NOTE: Be sure the master power switch, located on the rear panel of the monitor, is in the off position.
The master power switch turns off all power to the monitor.
Installing the Monitor Pedestal Base
NOTE: Do not install the pedestal base  if the monitor will be used on a wall, sw ing arm, or other
mounting fixture; instead see the section on 
Mounting the Monitor on page 17  in this chapter.
1. Using both hands, position the monitor over the pedestal base.
CAUTION: Do not touch the surface of the LCD pane l. Pressure on the panel may cause non-
uniformity of color or disorientation of the liquid cr ystals. If this occurs the screen will not recover
to its normal condition.
2. Press down firmly on the monitor to lock the pedestal base in place. When the base locks, it will
make a clicking sound.
