4. Operating Instructions

1. Power On/Off: Ensure your Motorola two-way radio is powered on. The speaker microphone draws power directly from the radio.
2. Transmit (PTT): To transmit your voice, press and hold the Push-To-Talk (PTT) button located on the side of the speaker microphone. Speak clearly into the microphone. Release the PTT button when you are finished speaking to return to receive mode.
3. Receive Audio: Incoming audio from your radio will be played through the speaker on the front of the microphone.
4. Using Earpiece (Optional): For private listening, plug a 3.5mm listen-only earpiece into the audio jack located on the side of the speaker microphone. This will mute the main speaker and direct audio to the earpiece.

5. Maintenance

• Cleaning: Wipe the speaker microphone with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
• Storage: Store the microphone in a dry, cool place away from direct sunlight and extreme temperatures when not in use.
• Cable Care: Avoid excessive pulling or twisting of the coiled cable to prevent damage.
• Connector Inspection: Periodically check the 2-pin connector for any signs of wear or damage.

6. Troubleshooting

• No Audio from Speaker Mic:
  • Ensure the 2-pin connector is fully and securely inserted into the radio's ports.
  • Check the radio's volume level.
  • If an earpiece is connected, ensure it is functioning correctly or remove it to test the main speaker.
• Unclear Transmission:
  • Speak directly into the microphone, ensuring it is not obstructed.
  • Verify that the PTT button is fully pressed during transmission.
  • Check the radio's settings for microphone gain or noise reduction, if applicable.
• Intermittent Connection:
  • Inspect the cable and connectors for any visible damage or loose connections.
  • Ensure the radio's ports are clean and free of debris.
