2 Safety and maintenance guidelines
Important safety information
A power cord is included with the display. If another cord is used, use only a power source and
connection appropriate for this display. For information on the correct power cord set to use with the
display, refer to the
WARNING! To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding feature. The grounding plug is an important safety 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.
For your safety, do not place anything on power cords or cables. Arrange them so that no one can
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.
Power cord set requirements on page 62.
To reduce the risk of serious injury, read the
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
and/or on the documentation CD, if one is included with the display.
CAUTION: For the protection of the display, as well as the media player/computer, connect all
power cords for the media player/computer and its peripheral devices (such as a display, 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 display.
WARNING! Displays that are inappropriately situated on dressers, bookcases, shelves, desks,
speakers, chests, or carts can fall over and cause personal injury.
Care should be taken to route all cords and cables connected to the display so that they cannot be
pulled, grabbed, or tripped over.
CAUTION: Do not place the device in a location where water may drip and/or splash on the device.
Do not place an object that contains water, such as a flower vase, on the device.
Maintenance guidelines
To enhance the performance and extend the life of the display:
Safety and Comfort Guide
. It describes proper
www.hp.com/ergo
Do not open the display cabinet or attempt to service this product yourself. Adjust only those
●
controls that are covered in the operating instructions. If the display 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 display, as indicated on the label/
back plate of the display.
ENWW Important safety information 3
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 display near an outlet that you can easily reach. Disconnect the display by grasping
the plug firmly and pulling it from the outlet. Never disconnect the display by pulling the cord.
Turn the display off when not in use. You can substantially increase the life expectancy of the
●
display by using a screen saver program and turning off the display when not in use.
CAUTION: Burn-in or image sticking might occur on displays which display the same static
image on the screen for prolonged periods of time. To avoid burn-in or image sticking and to
prolong the life of the display, you should activate one of the four ISM selections in the OSD,
activate a screen-saver application, periodically cycle between static information and moving
images, or turn off the display when it is not in use for prolonged periods of time.
Slots and openings in the cabinet are provided for ventilation. These openings must not be
●
blocked or covered. Never push objects of any kind into cabinet slots or other openings.
Do not drop the display 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 display in a well-ventilated area, away from excessive light, heat or moisture.
●
When removing the display base, you must lay the display face down on a soft area to prevent it
●
from getting scratched, defaced, or broken.
4 Chapter 2 Safety and maintenance guidelines ENWW
Cleaning the LD4730
1. Turn off the display and unplug the power cord from the back of the unit.
2. Dust the display by wiping the screen and the cabinet with a soft, clean antistatic cloth.
3. For more difficult situations such as removing fingerprints or other substances from the display
screen, use a foam window cleaner with no petroleum derivatives or alternatively use a 50/50
mix of water and isopropyl alcohol sprayed onto a cloth to clean the screen surface. Make sure
to protect against dripping any liquid under the bezel.
CAUTION: Never spray the cleaner directly on the screen surface. It might seep behind the bezel
and damage the electronics.
CAUTION: To clean the display screen or cabinet, do not use cleaners that contain any petroleum-
based materials such as benzene or thinner or any volatile substance. These chemicals might
damage the display.
Cleaning the LD4730G
The protective glass on the LD4730G is extremely easy to clean. Most marks wipe off with a dry
cloth. Use a foam window cleaner with no petroleum derivatives to remove more difficult substances.
Avoid scrubbing with any abrasive materials or scraping, as this can scratch the glass.
Shipping the display
Keep the original packing box in a storage area. You might need it later if you move or ship the
display.
ENWW Maintenance guidelines 5
3 Setting up the display
The display offers multiple connections for video and audio input. Analog video is input through the
VGA port, while digital video can be input through either Video Over Ethernet (VOE) or DisplayPort.
Sound can be transmitted with accompanying video through VOE or DisplayPort. To play sound
accompanying VGA video, use the audio connection.
Control data, such as power-on or input-select, can be sent through the infrared remote control, an
attached media player/computer via RS-232, a networked media player/computer via Ethernet (use
the HP Network Sign Manager software), or using the control panel buttons on the back of the
display.
The displays can be mounted on a stand or a wall. The stand allows good access to the control
panel.
With wall mounting, you can control the display with the remote or through software running on a
media player/computer. The HP Network Sign Manager is designed for this purpose.
Displays can be set up in a tiled array. See
sensor is particularly helpful for displays mounted in an array. Displays can be connected by their IR
ports with the IR daisy chain Cable and be controlled either as a group or singularly using the remote
control (See
Unpacking
CAUTION: Always use the handles on the back of the display to lift or move it. Avoid holding on to
the bezel or frame.
Care must be taken to avoid breaking or scratching the glass surface of the LD4730G model display.
Size and weight make it advisable for two people to unpack it together. When laying it flat, either lay it
on its back or on a padded, flat surface. When handling the display, always use the four handles on
the back of the display and avoid placing hands on the bezel or frame to lift or move the display.

Mounting a single display on a stand (Sold Separately)
The stand kit is an optional accessory available from HP. It allows you to mount a single display in
landscape position. To mount the display on the stand:
1. Remove the four M4 x 32 mm (1.26 in) screws and stand from the box.
Figure 3-8 Stand accessory contents
2. Place a soft cloth on the table and place the display with the screen facing downward. Connect
the stand as shown in the following figure.
Figure 3-9 Securing the stand to the display
The long side of the foot should face forward when the screen is upright.
Installing the HP LD4730 Frame System (Sold Separately)
The frame system creates a 10 mm border around one or more LD4730 displays, giving the edge a
finished look. To frame a group of displays, you need as many kits as you have displays in a row or
column, whichever is greater. For example, three kits will frame a 3 x 3 group, a 3 x 1 group, or a 1 x
3 group.
The frame kit includes four rails, one each for top, bottom, left and right. It also contains four
interchangeable corner pieces and four interchangeable straight connectors.
The rails are labelled TOP for the top in landscape position, BOTTOM for the bottom in landscape
position, RIGHT for your right side as you face the front of the screen, and LEFT for your left side as
you face the front of the screen. All the screw holes match for the one rail that goes to each side; no
force is needed. Attempting to attach the wrong rail could damage the bezel.
When you frame a single array, the numbers on the rails match at each corner:

To frame a single display, attach the top rail to the top of the display with three of the large (M4 x 10
mm) screws provided. The rail overlaps the bezel of the display. Attach the bottom, left, and right rails
in the same manner, leaving the two small holes at each end open.
Figure 3-10 Attaching rails
Attach the four corner pieces with four small (M3 x 5 mm) screws each. These overlap the rails and
secure their ends.
Figure 3-11 Attaching corners
ENWW Installing the HP LD4730 Frame System (Sold Separately) 13
Framing a group of displays is similar to framing a single display except that you will use some of the
straight connectors to cover the gap between adjacent displays.
Figure 3-12 Framing an array
Attach corners and straight connectors after the rails are in place.
Figure 3-13 Attaching corners and connectors
When you frame an array, the peripheral displays can no longer move independently. For this reason,
the following tasks may best be done before framing:
Color Calibration
●
Attaching all cables
●
Putting the main power switch in the ON (|) position
●
Horizontal, vertical and depth adjustment of all displays
