External Speakers and Microphone

External speakers and microphones are plug-and-play accessories. You can connect an external PC-type

microphone and powered speakers (with amplifier) on the Cisco IP Phone by using the line in/out jacks.

Connecting an external microphone disables the internal microphone and connecting an external speaker

disables the internal phone speaker.

Important Headset Safety Information

When you plug in your headset, lower the volume of the headset speaker before you put the headset on. If

you remember to lower the volume before you take the headset off, the volume will start lower when you

plug in your headset again.

Be aware of your surroundings. When you use your headset, it may block out important external sounds,

particularly in emergencies or in noisy environments. Don't use the headset while driving. Don't leave your

headset or headset cables in an area where people or pets can trip over them. Always supervise children who

are near your headset or headset cables.

Cisco IP Phone Accessories

Using poor quality external audio devices, playing loudspeakers at very loud volumes, or placing the microphone

very close to the loudspeaker may result in undesirable echo for other parties on your speakerphone calls.

High Sound Pressure—Avoid listening to high volume levels for long periods to prevent

possible hearing damage.
