Assistive technologies
Some accessibility technologies are available through the Accessibility Options program. Depending
on your operating system, the number of accessibility options available varies. In general, accessibility
options enhance the way users with hearing, vision, or mobility limitations navigate and use their computer.
For example, some users might not have the fine motor skills required to use a mouse or select key
combinations. Other users might require larger fonts or high-contrast display modes. In some cases,
magnifiers and built-in speech synthesizers are available. For detailed information about each of these
features, consult the Microsoft help information system.
To use the Accessibility Options program, open Control Panel and click Ease of Access ➙ Ease of
Access Center .
Screen reader technologies
Screen-reader technologies are primarily focused on software program interfaces, help information systems,
and various online documents. However, in the case where a screen reader cannot read documents, the
document must first go through a conversion process. One solution converts Adobe PDF files into a format
that is read by the screen-reader programs. This solution is a Web-based service provided by Adobe
Systems Incorporated. Through http://access.adobe.com, Adobe PDF documents can be converted to
HTML or plain text in many languages. One conversion option converts PDF documents on the Internet. A
second option enables users to submit the URL of an Adobe PDF file through e-mail to convert it to HTML or
ASCII text. Adobe PDF files on a local hard disk drive, local CD-ROM, or LAN also can be converted by
attaching the Adobe PDF file to an e-mail message.

Travel tips
Use the following travel tips to travel more confidently and efficiently with your computer.
• Although it is safe to allow your computer to go through the x-ray machines at airport security stations, it
is important to keep your eyes on the computer at all times to prevent theft.
• Consider bringing an electrical adapter for use in an airplane or automobile.
• If you carry an ac power adapter, detach the ac cord from it to avoid damaging the cord.
Travel tips on airplanes
If you carry your computer into an airplane, take note of the following tips:
• If you intend to use your computer or wireless services (such as Internet and Bluetooth), check with the
airline for restrictions and availability of services before boarding the airplane. If there are restrictions
on the use of computers with wireless features on the airplane, you must abide by those restrictions. If
necessary, disable wireless features before boarding.
• Be careful about the seat in front of you on airplanes. Angle your computer display so that it does not get
caught when the person in front of you leans back.
• When taking off, remember to turn off your computer or put it into hibernation mode.
