When the monitor is cold and brought into a room or the room temperature goes up quickly, dew
condensation may occur inside and outside the monitor. In that case, do not turn the monitor on and
wait until dew condensation disappears, otherwise it may cause some damages to it.
In order to suppress the luminosity change by long-term use and to maintain the stable luminosity,
please use the monitor with the lower brightness.
The screen may have defective pixels. These pixels may appear as slightly light or dark area on the

This monitor will not likely require adjustment. Variations in video output and application may
require adjustments to the monitor to optimize the quality of the display.
For best performance, the monitor should be operating in native resolution 1600x1200. Use
the Display control panel in Windows to choose 1600x1200 resolution. Operating in other
resolutions will degrade video performance.
All control adjustments are automatically memorized.

4.3 DICOM GSDF Calibration
The ARMSTEL Amedicom® MDA2120-A medical dual-mode display has the built-in calibrated
DICOM GSDF compliant BARTEN curve for medical image display, with patented (pending)
ARMSATTTM technology embedded. It also allows user to push single “CAL” button to do the
automatic backlight adjustment and calibration. MDA2120-S is accurately DICOM Part 14
calibrated at the production. To adjust the display from shifting away from the DICOM
characteristic display function, ARMSTEL provides a dedicated tool for user to calibrate the
display lookup table whenever needed. The tool includes a calibration software package,
TM
Calispector
CalispectorTM software provides a user control function to calibrate the DICOM GSDF BARTEN
curve on site to prevent the shifting. The software allows user to calibrate at different levels of
accuracies, i.e., using 2048, 1024, 512, or 256 grayscales (grayscale luminance levels) to
interpolate the BARTEN curve. Using 2048 grayscales takes approximately 40 minutes to
restore the default setting, whereas 1024 takes around 20 minutes. 512 gr ayscales calibration
takes about 10 minutes while 256 grayscales takes less than 5 minute to complete the
calibration.
Calibration steps are as follows:
1) Install ARMSTEL Amedicom
following ARMSTEL website:
and a SimluxTM meter compatible with the LCD display. ARMSTEL Amedicom®

CalispectorTM software by downloading the software from the
http://www.armstel.com/Amedicom®-dicom-calispector-software.php

Adjust the <Brightness> (The backlight of the LCD monitor has a
fixed life span. When the screen becomes dark or begins to
flicker, please contact your dealer.)
- Please check if you use the screen saver or timer when
displaying the same image for long time.
- Image sticking is inherent characteristic of the panel. Avoid
displaying the same image for long time.
This is due to the characteristics of the panel itself, not the LCD
monitor.
6. Cleaning
Periodic cleaning is recommended to keep the monitor clean and to prolong its operation lifetime.
Note: Never use thinner, benzene, alcohol (ethanol, methanol, or isopropyl alcohol), abrasive cleaners, or
other strong solvents, as these may cause damage to the cabinet or LCD panel.
Cabinet
To remove stains, wipe the cabinet with a soft, lightly moistened cloth using a mild detergent. Do not spray
wax or cleaner directly into the cabinet.
LCD Panel
The LCD surface can be cleaned with a soft cloth, such as cotton or lens paper.
If necessary, stubborn stains can be removed by moistening part of a cloth with water to enhance its
cleaning power.
