Step 1: Check for Accidental Mute Button Press
The Icom HM-133 microphone has multiple buttons that can be programmed or set to mute functionality. To unmute your Icom HM-133 microphone, start by checking if you have accidentally pressed the mute button. Typically, pressing the MUTE button again will unmute the microphone.

Step 2: Resetting the Microphone Settings
If pressing the mute button doesn’t work, it’s time to check the microphone’s settings.
