Important handling information for your Mac
Operating environment. Operating your Mac mini outside these ranges may affect performance:
Operating temperature: 50° to 95° F (10° to 35° C)
Storage temperature: -40° to 116° F (-40° to 47° C)
Relative humidity: 5% to 90% (noncondensing)
Operating altitude: Tested up to 16,404 feet (0 to 5000 meters)
Do not operate your Mac mini in areas with significant amounts of airborne dust, or smoke from cigarettes, cigars, ashtrays, stoves, or fireplaces, or near an ultrasonic humidifier using unfiltered tap water. Tiny airborne particles produced by smoking, cooking, burning, or using an ultrasonic humidifier with unfiltered water may, in rare instances, enter the ventilation openings of your Mac mini.
Carrying your Mac mini. Before you lift or reposition your Mac mini, shut it down and disconnect all cables and cords. To lift your Mac mini, hold its sides.
Using connectors and ports. Never force a connector into a port. Before you plug the power cord into the power port, make sure the power port is completely free of debris. When connecting a device to a port, make sure the port is completely free of debris, that the connector matches the port, and that you have positioned the connector correctly in relation to the port.
Important: Use only the original cables that came with your computer or accessory, or cables sold at an Apple retail store or online at apple.com or your local Apple Store.
