1:50 What is Talk Through Your Ears® (TTYE) Technology?

  • The ultimate two-radio radio accessory that allows users to transmit and listen to radio communications through specialized earpieces
  • Small microphone located in the earset picks up the voice in the ear canal

  • CavCom’s TTYE system connects to your radio system
  • If you need to upgrade or change radios, they simply send a new adapter cable – you don’t need to purchase a new communication system

8:15 Is TTYE Dependent on Specific SCBAs or Suits?

  • Since it’s an in-ear product, TTYE works independently of PPE
  • Can be used in or out of your suit and with or without PPE
