SupraPlus Wideband: Callers Unable to Hear

When I answer a call on my SupraPlus Wideband headset, callers are unabler to hear me. How can I fix this issue?
To fix this issue
For voice tube models 
  • Determine if the voice tube is positioned properly. If not, try various other positions.
  • Determine if the voice tube is clogged, remove the voice and see if the caller can hear you. If the caller can hear you, it means there is a clog in the voice tube. A temporary solution to a clogged voice tube is to gently rinse warm water through the voice tube for a minute then manually swing or shake it dry.
For noise canceling models
  • Ensure the microphone is facing your mouth and is in a proper position.
  • Ensure that the transmit volume control of the amplifier is set properly.
