Operating environment
The Macintosh is designed to operate reliably in a suitable environment. To
maintain this environment, do the following:
- Keep the Macintosh and components out of direct sunlight and free from
exposure to rain or other moisture.
- Operate the Macintosh only at temperatures between 50 degrees and 104
degrees Fahrenheit (between 10 degrees and 40 degrees Celsius), and at a
humidity ranging from 20 percent to 80 percent.
- Be certain that all components are placed so that none of their ventilation
areas are blocked or partially blocked. Do not put papers, disks, or other
items over the air circulation areas of the system, even temporarily.
Preventing proper air circulation could result in overheating of a component
and possible damage or unreliable operation.
- If your Macintosh and components are placed so that you see interference on
the monitor's screen or see or hear interference on a nearby television or
radio, move the affected components farther apart.
Cleaning system components
You can clean the exterior of most Macintosh system components, the
computer's screen, and the mouse's mechanical parts.
Computer and peripheral-device cases
Clean the case of your Macintosh or a peripheral device as follows:
- Use a damp, soft, lint-free cloth to clean the computer's exterior. Avoid
getting moisture in any openings.
- Do not use aerosol sprays, solvents, or abrasives when cleaning the
computer or other components.
Screen
When cleaning the computer's screen, put household glass cleaner on a soft
cloth and wipe the screen. Do not spray the cleaner directly onto the screen,
because the liquid may drip into the computer's interior.
Mouse
The mouse contains a small ball that rolls as you move the device. You can
keep this ball free of dirt and grease by using the mouse on a clean, hard
surface and cleaning it occasionally.
Follow these steps to clean the mouse:
1. Switch off the Macintosh.
