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.
