I get feedback noise from a microphone. What should I do?

• Feedback noise can occur when the microphone is too close to the projector's speaker. To prevent feedback noise, move the microphone away from the projector's speaker.
  
  If you are using a wireless microphone system, the receiver's gain (or volume) may be set too high. Lower the receiver's gain/volume then adjust the projector's volume. The louder the projector's volume is set, the greater the distance you need to be away from the speaker to prevent feedback.
