·Microphone of use:
 plug in the mcirophone to microphone "MIC"socket. Turn the microphone switch to "ON" position, speak into the microphone, adjust the amplifier's volume control, so that the volume is appropriate. When handing the microphone to others or when not in use, the microphone should be switched to "OFF" position.

If this happens, pull the mcirophone away from the speaker. As a microphone is a precision component part, be careful not to drop, hit or be given a strong shocl.
