part responsible for compliance could void the user’s authority to operate the
equipment

FCC- Class B

This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a communications.
However, there is no guarantee that interference will not occur in particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of the
following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and receiver.

- Connect the equipment into an outlet on a circuit different from that to which

the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.

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 color

flat panel display HL1926 preferable to conventional CRT monitors.

Embedded LUT-This monitor is factory calibrated to achieve DICOM part 3.14

compliance and Linear gray level reproduction at the factory set point. 5 different settings
are stored within the display.

Screen resolution- HL1926 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.
