Using the AccuMic II
The AccuMic II is a plug-and-play microphone; the only function that is controlled
manually is Mute. Press the Mute button (on top of the mic pad) to mute the
AccuMic II’s mics; press Mute again to unmute the mics.
When using two connected AccuMic IIs, pressing the Mute button on either
unit mutes/unmutes both AccuMic II mic pads.
The AccuMic II uses three LEDs that indicate the direction your voice is com-
ing from, letting you know you’re being heard at the distant site.
Troubleshooting
If you have trouble with your AccuMic II, the unit might not be set up properly or
other equipment might be malfunctioning. To begin, check the following:
• The AccuMic II power supply is plugged into a 120/240-volt electrical outlet.
• The base connector cable from the power supply to the AccuMic II is securely
connected.
• Connections to the video codec and television are secure.
• The equipment the other party is using is comparable in quality to your video
conferencing system and is working properly.
• The LEDs on the top of the AccuMic II illuminate in the direction of the par-
ticipant speaking. Participants need to be within 10 feet of the
AccuMic II.

If problems persist, please contact our Technical Services Group.
