You can also install the following additional expansion cards in your
Macintosh:
m the Apple External Video Connector kit that allows video mirroring on an
external monitor
m a TV tuner card that allows you to watch TV on your Macintosh
Other video cards that let you perform video editing and other functions may
also be available for your computer.
This appendix contains instructions for installing a PCI card or a
communication card. To install a video input card or a TV tuner card (if you
don’t already have these cards installed) or the Apple External Video
Connector kit, follow the instructions that came with the card or kit.
WARNING To avoid damaging your computer and expansion card, do not
attempt to install any expansion card without first checking the
documentation for that card. If the documentation specifies that an
Apple-certified technician must install the card (usually because
the installation requires special training or tools), consult the service
and support information that came with your computer for instructions
on how to contact an Apple-authorized service provider or Apple for
assistance. If you attempt to install the card yourself, any damage you
may cause to your computer or card will not be covered by the limited
warranty on your computer. If the card is not an Apple-labeled product,
check with an Apple-authorized dealer or service provider to see if you
can install it yourself.
