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.
When operating your equipment:

Do not use your equipment in a wet environment, for example, near a bath tub, sink, or swimming
