Connecting External Devices

	To connect an audio device
	You can plug in an external microphone, external speakers, or headphones. In
	addition, if you connect your notebook to the port replicator, you can plug in a stereo
	source (such as a CD player) or a device that accepts digital audio (such as a digital
	audio recorder).
CAUTION	The headphone and line-in jacks are three-terminal stereo jacks. They are not
	compatible with two-terminal mono plugs. Connecting a mono plug into either
	of these jacks may damage the notebook.
	Attach the audio cable to the corresponding audio port on the notebook or port
	replicator.

	connected to the corresponding port on the port replicator is ignored.
