FAQ:

Q: How does the acoustic tube earpiece work?

A: Your radio drives the Transducer (a small speaker) which moves a small amount of air in the tube. The tube is tightly sealed to your ear and in this way you hear your radio while blocking ambient noise to that ear.

Q: How do I fix my earpiece dust?

A: Use a soft cleaning cloth, soft brush, or some compressed air to wipe or blow away any debris freed by your brushing.

Q: Where do you clip a radio earpiece?

A: It clips to the uniform on the shoulder and falls just above the collar bone. The cable runs from your radio behind your back. This is most common because the speaker mic rests close to your mouth and ear, so you are heard clearly over the radio
