3. Operating Instructions

Once connected, audio from your two-way radio will be transmitted directly to the earpiece. Ensure your radio's volume is set to an appropriate level for clear listening.

The headset includes an in-line microphone for speaking. To transmit your voice:
- Locate the Push-to-Talk (PTT) Button: The microphone unit typically has a button that functions as a PTT control.
- Press and Hold PTT: Press and hold the PTT button while speaking clearly into the microphone. Position the microphone close to your mouth for optimal voice pickup.
- Release PTT: Release the PTT button when you have finished speaking to return to receive mode.
