2 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.
Attaching the Monitor Base
1. Lift the base from the monitor box and set it on a flat surface such as a table top.
2. Using both hands, lift the monitor from its box, position the pedestal over the base, and press
down firmly to lock it in place. Be sure the base is securely locked in place and adjust the tilt
angle to the desired position.
CAUTION: Do not touch the surface of the LCD panel. Pressure on the panel may cause non-
uniformity of color or disorientation of the liquid crystals. If this occurs the screen will not recover to its
normal condition.
Figure 2-1 Attaching the Monitor Base
NOTE: To remove the base, press inward on the tab in the center of the underside of the base and
pull the base from the pedestal.

WARNING! To reduce the risk of electric shock or damage to the equipment:
Do not disable the power cord grounding plug. The grounding plug is an important safety
feature.
Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all
times.
Disconnect power from the equipment by unplugging the power cord from the electrical outlet.
For your safety, do not place anything on power cords or cables. Arrange them so that no one
may accidentally step on or trip over them. Do not pull on a cord or cable. When unplugging from
the electrical outlet, grasp the cord by the plug.
To operate the HP t150 or t200 Zero Client for MultiSeat, refer to the documentation provided with the
HP MultiSeat Desktop Computer.
Mounting a Thin Client to the Monitor with the HP Quick Release
You can attach a thin client to the LE1852ms monitor using the HP Quick Release included with the

Turning on the Monitor
1. Press the power button on the computer to turn it on.
2. Press the power button on the front of the monitor to turn it on.
CAUTION: Burn-in image damage may occur on monitors that display the same static image on
screen for a prolonged period of time.* To avoid burn-in image damage on the monitor screen, you
should always activate a screen saver application or turn off the monitor when it is not in use for a
prolonged period of time. Image retention is a condition that may occur on all LCD screens. Monitors
with a “burned-in image” are not covered under the HP warranty.
* A prolonged period of time is 12 consecutive hours of non-use.
NOTE: If pressing the power button has no effect, the Power Button Lockout feature may be
enabled. To disable this feature, press and hold the monitor power button for 10 seconds.
NOTE: You can disable the power LED in the OSD menu. Press the Menu button on the front of the
monitor, then select Management > Bezel Power LED > Off.
When the monitor is powered on, a Monitor Status message is displayed for five seconds. The
message shows VGA as the current active signal, the current preset display resolution, and the
recommended preset display resolution.

Entering User Modes
The video controller signal may occasionally call for a mode that is not preset if:
You are not using a standard graphics adapter.
●
You are not using a preset mode.
●
It this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen
display. Your changes can be made to any or all of these modes and saved in memory. The monitor
automatically stores the new setting, then recognizes the new mode just as it does a preset mode. In
addition to the factory preset modes, there are at least 10 user modes that can be entered and
stored.
Energy Saver Feature
The monitors support a reduced power state. The reduced power state will be entered into if the
monitor detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon
detecting the absence of these signals, the monitor screen is blanked, the backlight is turned off, and
the power light is turned amber. When the monitor is in the reduced power state, the monitor will
utilize .5 watts of power. There is a brief warm up period before the monitor will return to its normal
operating mode.
Refer to the computer manual for instructions on setting energy saver features (sometimes called
power management features).
NOTE: The above power saver feature only works when connected to computers that have energy
saver features.
By selecting the settings in the monitor's Energy Saver utility, you can also program the monitor to
enter into the reduced power state at a predetermined time. When the monitor's Energy Saver utility
causes the monitor to enter the reduced power state, the power light blinks amber.
