1. Application
This high-resolution color display is specifically designed to meet the rigorous
performance standards needed for diagnostic, interventional radiology, and other
medical applications. To guarantee image integrity, features include accurate
signal conversion and a wide range of interfacing options.
Compact design -Low weight and small size with improved performance make the
monochrome flat panel display HL1928M preferable to conventional CRT monitors.
Embedded LUT(Look Up Table )-This monitor is factory calibrated to achieve
DICOM part 3.14 compliance and Linear gray level reproduction at the factory set
point. Five different settings are stored within the display.
Screen resolution- HL1928M is equipped with a panel with Super In Plane
Switching technology. The optimal picture resolution is 1280 x 1024 pixels. Video
signals with other resolutions typical to medical engineering are optimally zoomed
in or out to the screen size.
Fast backlight stability- The luminance stabilization circuit employs a built in
photo sensor to keep the back-light lamps at a constant luminance for consistent
calibration over the life of the display and can control the back light system
automatically to extend the life of the monitor and achieve very short warming up
time.
Multi-interface for video inputs- Support DVI-D,DVI-A,BNC (combined with
optional BNC cable) video inputs.
Digital control interface-The monitor has an asynchronous RS-232 architecture
interface for remote control, such as Brightness, Contrast etc. The protocol of RS-232
is compatible with GE OEC 16 inch CRT monitor.
Left and Right Monitor-The monitor can be supported in pairs. The left monitor has
protective glass in the front and the right monitor has infrared touch screen in the
front.
Remark -All relate to the touch screen only applies to HL1928M-R.

2. Declarations
Safety precautions
WARNING:
To avoid risk of electric shock, this equipment must only be connected to a
supply mains with protective earth.
APPLIANCE COUPLER or separable plug of is used as isolation means to isolate the
equipment from mains supply.
Accessory equipment connected to the analog and digital interfaces must be
certified according to the respective IEC/EN standards (e.g. IEC/EN 950 for data
processing equipment and IEC/EN 60601-1 for medical equipment ).
Medical Equipment
With respect to electric shock, Fire and mechanical
hazards only in accordance with UL 60601-1
and CAN/CSA C22.2 No. 601.1
Furthermore all configurations shall comply with the valid version of the system
standard IEC/EN 60601-1-1.Everybody who connects additional equipment to
the signal input connector or signal output connector configures medical system,
and is therefore responsible that the system complies with the requirements of
the valid version of the system standard IEC/EN 60601-1-1.If in doubt, consult
our technical service department or your local distributor.
Regular maintenance and calibration are recommended
Please note that liquid crystal displays such as the HL1928M do not have a
failure rate of zero and image parameters may change over time (e.g.
luminance or discoloration). Please ensure that all measures are taken to
prevent injuries or incorrect diagnoses. Regular maintenance and calibration
are recommended.
Correct and safe operation of the flat panel displays is dependent on proper
transport, storage, installation and assembly, as well as careful operation and
maintenance. The units must only be used for applications for which monitors
are normally used. The information in the Section "Technical data" must be
observed exactly.
For the sake of safety, the following precautions must be observed:

Danger: There is a danger to life if the warning information is not observed.
Severe personal injury or damage to property may occur.
Do not open the unit yourself.
Certain components inside the units are at high-voltage, i.e. touching these
components presents a danger to life!
Only use a perfect power supply cable
A damaged power supply cable may result in a fire or electric shock. When
disconnecting the power supply cable, always do so by holding the plug.
Only use the same type of fuse
T2A/250V
Do not insert any objects into the housing
Objects inserted into the housing may result in damage to the unit or personal
injury.
Do not place any objects on top of the units
Penetrating liquids may result in a fire or electric shock.
Connection
No contact to a patient must occur when handling the cables.
To avoid risk of electric shock, this equipment must only be connected to a
supply mains with protective earth.
Do not hurt yourself, when moving the display
The display can be tilted backwards and forwards. Please, pay attention not to
hurt yourself, when moving the display. Fingers or small objects may get stuck
at the bottom of the display.
When moving the display up and down (height adjustment), make sure you do
not squeeze your hand or any other object. The minimum distance between the
display edge and the bottom is only 59 mm.
Caution
Incorrect installation may result in extensive damage to property.

Installation should be carried out by trained personnel
When installing your medical electrical system with our products in an
environment with patients, please observe the safety requirements of EN
60601-1-1 (IEC 601-1-1) for "Specifications for the safety of medical electrical
systems" in order to prevent injury to patients and users of your systems.
For certain applications, the video earth can be separately connected to the PE
via the additional PE connection in the plug panel (observe IEC 601-1-1).
Take appropriate measures to particularly ensure that discharge currents
remain below the required limits: Appropriate measures:
- Disconnecting devices for signal input or output unit
- Use of a safety transformer
- Use of additional PE conductor
Only use the signal cables and interface cables specified by the manufacturer
for the installation.
Use power cables with a PE contact. Only insert into sockets with a PE contact.
For certain applications, the video earth can be separately connected to the PE
via the additional PE connection in the plug panel (observe IEC 601-1-1).
Close the plug panel using the provided cover , and secure using the screws.
Mounting information: The stability of the display must be guaranteed
following mounting of the foot/holder. The immersion depth of the mounting
screws has to be 10 to 12 mm including a 3 mm VESA mounting plate. (See
also table "Mounting screws" on the following). All these requirements are
satisfied when using the original foot. All requirements must be observed when
using customer-specific mounting solutions.
Notice for users: The plug panel closed by the cover, must not be opened by
users.
Servicing information: If housing components have to be removed for
servicing, this must not be carried out in the presence of patients, the user, or
other persons not involved with servicing.
The following applies to installations in the USA and Canada: Molded power
supply plugs must comply with the requirements for "Hospital Grade
Attachments" UL 498.
