HME HS25D User manual

  • Hello! I've reviewed the user guide for the HME HS25 and HS25D headsets. This document provides instructions on adjusting the headset, using the microphone boom, and connecting to an HME beltpack. I'm ready to help with questions regarding these headsets and their usage.
  • How do I turn the headset microphone ON?
    How do I turn the headset microphone OFF?
    Can the microphone boom be positioned on either side of the head?
