Entel EA12 Earpiece Microphone User guide

  • Hello! I've reviewed the Entel Earpiece Microphone Quick Start User Guide, which describes the proper use of the EA12, HT500 EA12/950, HT700 EA12/750, DX-IS EA12/DX, DX, DN EA12/DX and DT500 DT800, DT900 EA12/DT9 models. This guide covers fitting, operation using the PTT button, and the specifications for the device. I am ready to answer questions about the device and the content of the guide.
  • How do I fit the earpiece?
    Where should the PTT button be placed?
    How do I transmit?
    How to use microphone?
    What should I do before attaching an audio accessory?
