FCC Information 
This equipment has been tested and found to comply with the limits of a Class B digital 
device, pursuant to Part 15 of the FCC Rules. 
These limits are designed to provide reasonable protection against interference. This 
monitor can radiate radio frequency energy and, if not installed and used in accordance 
with the instructions, it may interfere with other radio communications equipment. There 
is no guarantee that interference will not occur in a particular installation. 
If this equipment is found to cause harmful interference to radio or television reception, 
the user is encouraged to try to correct the interference by carrying out one or more of 
the following measures: 
1. Reorient or relocate the receiving antenna. 
2. Increase the distance between the color monitor and the subject of 
interference. 
3. Plug the monitor into an outlet on a different electrical circuit than the one to 
which the subject of interference is connected. 
4. Consult the dealer or an experienced radio/TV technician for help. 
NOTICES TO THE USER: 
This device complies with part 15 of the FCC Rules. Operation is subject to the following 
two conditions: 
(1) this device may not cause harmful interference, and (2) this device must accept any 
interference received, including interference that may cause undesired operation. 
FCC WARNING: 
This equipment generates or uses radio frequency energy. Changes or modifications to 
this equipment may cause harmful interference unless the modifications are expressly 
approved in the instruction manual. The user could lose authority to operate this 
equipment if an unauthorized change or modification is made.

Electromagnetic compatibility 
Warning 
When this device is connected with other electrical equipment, leakage 
currents may be additive. To minimize total leakage current per patient, 
ensure that all systems are installed according to the requirements of IEC 
60601-1-1. 
Caution 
Portable and mobile RF communications equipment may affect the normal function of 
the display. Do not use cables or accessories other than those provided with the display, 
as this may result in increased electromagnetic emissions or decreased immunity to such 
emissions. If the display is used adjacent to other equipment, observe and verify normal 
operation of the display in the configuration in which it will be used prior to using it in a 
surgical procedure. Consult the tables below for guidance in placing the display.   
 
Like other electrical medical equipment, the MD-4221 requires special precautions to 
ensure electromagnetic compatibility with other electrical medical devices. To ensure 
electromagnetic compatibility (EMC), the display must be installed and operated 
according to the EMC information provided in this manual. The display have been 
designed and tested to comply with IEC 60601-1-2:2001 requirements for EMC with other 
devices.

Recommendations for using your display system 
1. Optimize the lifetime of your display 
Enabling the Display Power Management System (DPMS) of your display (in the display’s 
Settings menu) will optimize LCD backlight lifetime by automatically switching off the 
backlight when the display is not used for a specified period of time. By default, DPMS is 
enabled on your display, but it also needs to be activated on your workstation. To do this, 
go to “Power Options Properties” in the “Control Panel”. 
Barco recommends setting DPMS activation after 20 minutes of non-usage. 
2. Use a screen saver to avoid image retention 
Prolonged operation of an LCD with the same content on the same screen area may 
result in a form of image retention. 
You can avoid or significantly reduce the occurrence of this phenomenon by using a 
screen saver. You can activate a screen saver in the “Display properties” window of your 
workstation. 
Barco recommends setting screen saver activation after 5 minutes of non-usage. A good 
screen saver displays moving content. 
In case you are working with the same image or an application with static image 
elements for several hours continuously (so that the screen saver is not activated), 
change the image content regularly to avoid image retention of the static elements. 
3. Understand pixel technology 
LCD displays use technology based on pixels. As a normal tolerance in the manufacturing 
of the LCD, a limited number of these pixels may remain either dark or permanently lit, 
without affecting the diagnostic performance of the product. To ensure optimal product 
quality, Barco applies strict selection criteria for its LCD panels. 
To learn more about LCD technology and missing pixels, consult the dedicated white 
paper available at www.barcomedical.com. 
Unpacking and handling tips 
The display is a precision instrument that requires proper care to maintain product 
operation and adherence to specification. Unpack the display and components carefully, 
then set up and handle the unit properly to avoid damage to the LCD panel. 
• Always lift and carry the display with 2 persons. 
• Use both hands to grasp the display case when lifting it from the shipping 
carton, but avoid touching the screen.  
						

							  
 
  15 
• Do not apply pressure to the screen or touch the screen with bare fingers or 
objects. Pressure can affect image quality. Cosmetics and oils on the skin are 
both detrimental to the screen and difficult to remove. 
• Allow the display to warm up to room temperature before turning it on. Avoid 
sudden temperature changes in the environment, as this may cause 
condensation, which damages the display. 
• Do not set up the display near strong light or heat sources. 
• Do not block the vents on the back of the display or install the display in a 
built-in enclosure. Blocked vents cause excessive heat to build up inside the 
display, increasing risk of fire. 
• When installing components, turn off your computer, but leave it plugged into a 
grounded outlet. 
• Do not remove the back cover or disassemble the display. There are no 
user-serviceable parts inside. 
Preventing fire and injury 
• Replace the power supply cables if damaged. 
• Use only the power source indicated in this guide or listed on the display. 
• Do not plug the power supply into an overloaded AC outlet or extension cord. 
Overloaded AC outlets and cords can result in electric shock or fire. 
• Do not drop or push objects into the display case. Internal components contain 
high voltage. 
• Unplug the power cord from the wall outlet during thunderstorms. 
• Do not place magnetic devices, such as motors, near the display.
