This is feedback between the microphone and the speakers. It
occurs in any sound system when input from a microphone is
fed to the speakers and the speaker volume is too loud. Adjust
the volume control.
PC Card problems
PC Cards (PCMCIA-compatible) include many types of
devices, such as a removable hard disk, additional memory,
or a pager.
Most PC Card problems occur during installation and setup
of new cards. If you are having trouble getting one or more of
these devices to work together, several sections in this chapter
may apply.
Resource conflicts can cause problems when using PC Cards.
