To use the connected microphone

Set “Mic Select” to “MIC” on page 1 of the Audio Setup menu. (See page 50.)

Notes on installation of the microphones

•Install microphone about 50 cm away from the participants.

•Install the speakers behind the microphones.

•Place the microphone in a quiet, echo-free location.

•Install microphones away from equipment that may cause noise.

•Avoid covering a microphone with paper, etc., or moving it. If you do either, extreme noise and echo may be heard temporarily by the remote party. In this case, wait until the echo disappears.
