Industry-standard connectors
The computer provides industry-standard connectors that enable you to connect assistive devices.
TTY/TDD conversion modem
The computer supports the use of a text telephone (TTY) or the telecommunications device for the deaf (TDD)
conversion modem. The modem must be connected between the computer and a TTY/TDD telephone. Then,
you can type a message on the computer and send it to the telephone.
Documentation in accessible formats
Lenovo provides electronic documentation in accessible formats, such as properly tagged PDF files or
HyperText Markup Language (HTML) files. Lenovo electronic documentation is developed to ensure that
visually impaired users can read the documentation through a screen reader. Each image in the
documentation also includes adequate alternative text so that visually impaired users can understand the
image when they use a screen reader.
Cleaning the computer
CAUTION:
Remove any media from the drives and turn off all connected devices and the computer. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to the
computer.
It is a good practice to clean the computer periodically to protect the surfaces and ensure trouble-free
operation. Use only mild cleaning solutions and a damp cloth to clean the painted surfaces of the computer.
Dust buildup compounds problems associated with glare, so remember to clean the screen periodically.
Wipe the screen surface gently with a soft, dry cloth, or blow on the screen to remove grit and other loose
particles. Depending on the type of the screen, moisten a soft, lint-free cloth with an LCD cleaner or liquid
glass cleaner and then wipe the screen surface.
Maintenance
With appropriate care and maintenance, the computer will serve you reliably. This section provides
information about maintaining the computer so that it can keep working in top order.
Basic maintenance tips
Here are some basic points about keeping the computer functioning properly:
• Keep the computer in a clean, dry environment. Ensure that the computer rests on a flat, steady surface.
• Do not cover any of air vents. These air vents provide airflow to keep the computer from overheating.
