- Attach Earpiece (Optional): If private listening is desired, insert the 3.5mm plug of the acoustic tube earpiece into the dedicated earpiece jack located on the side of the speaker microphone.
- Secure Microphone: Use the 360-degree rotating clip on the back of the speaker microphone to attach it securely to your collar, lapel, or other convenient location on your clothing or gear.
- Position Earpiece: Adjust the acoustic tube earpiece for a comfortable and secure fit in your ear. Use the small clip on the earpiece cable to manage excess cable and prevent snagging.

6. Operating Instructions
Once connected, the speaker microphone functions as an extension of your two-way radio.
- Receiving Audio: Incoming transmissions will be heard through the speaker on the microphone unit. If the earpiece is connected, audio will be routed to the earpiece for private listening.
- Transmitting Audio (Push-to-Talk - PTT): To transmit, press and hold the large Push-to-Talk (PTT) button located on the side of the speaker microphone. Speak clearly into the microphone grille. Release the PTT button to stop transmitting and return to receive mode.
