NOTE: In this section, equipment refers to monitors. 
 

IMPORTANT NOTICE FOR USE IN HEALTHCARE ENVIRONMENTS:  
Dell products are not medical devices and are not listed under UL or IEC 60601 (or equivalent). As a 
result, they must not be used within 6 feet of a patient or in a manner that directly or indirectly 
contacts a patient 
 

1.1 SAFETY: General Safety 

WARNING: To prevent the spread of fire, keep candles or other open flames away from this product 
at all times. 
 

When setting up the equipment for use: 

 

 

Place the equipment on a hard, level surface. Leave 10.2 cm (4 in) minimum of clearance on 
all vented sides of the computer to permit the airflow required for proper ventilation. 

 

Restricting airflow can damage the computer or cause a fire. 

 

Do not stack equipment or place equipment so close together that it is subject to 
recalculated or preheated air. 

 

NOTE: Review the weight limits referenced in your computer documentation before placing 
a monitor or other devices on top of your computer. 

 

Ensure that nothing rests on your equipment's cables and that the cables are not located 
where they can be stepped on or tripped over. 

 

Ensure that all cables are connected to the appropriate connectors. Some connectors have 
a similar appearance and may be easily confused (for example, do not plug a telephone 
cable into the network connector). 

 

Do not place your equipment in a closed-in wall unit or on a bed, sofa, or rug. 

 

Keep your device away from radiators and heat sources. 

 

Keep your equipment away from extremely hot or cold temperatures to ensure that it is used 
within the specified operating range. 

 

Do not push any objects into the air vents or openings of your equipment. Doing so can 
cause fire or electric shock by shorting out interior components. 

 

Avoid placing loose papers underneath your device. Do not place your device in a closed-in 
wall unit, or on a soft, fabric surface such as a bed, sofa, carpet, or a rug.
