- To finalize the pairing operation, restart all headsets. Power on the Master first, then Connection Level One headsets, and finally Connection Level Two headsets. This sequence is crucial for proper transmission.
- Once the green light on all headsets is steady, the connection is complete, and all headsets are ready for use.
Operating Instructions
Basic Communication
- Ensure all headsets are powered on and successfully paired as per the "Setup and Pairing Guide."
- Speak clearly into the microphone. The full-duplex system allows all connected users to speak and listen simultaneously.
Volume Adjustment
- To increase listening volume, short press the "Volume +" button.
- To decrease listening volume, short press the "Volume -" button.
Boost Mode Activation
- To switch between Boost Modes (1, 2, or 3) for enhanced signal quality, long-press the "Volume -" button for 3 seconds until you hear a 'Beep' sound, then release.
Remote Muting (Master Headset Only)
- The Master headset has a dedicated one-button function to mute all remote headsets. Refer to the specific button on your Master headset for this function (often indicated by a distinct color or symbol).
Real-time Monitoring
- Connect a 3.5mm TRS cable from your camera or recorder to the headset's 3.5mm monitoring port to listen to audio from external devices while communicating.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the headset. For stubborn dirt, a slightly damp cloth can be used. Avoid harsh chemicals or abrasive materials.
- Battery Care: Charge batteries regularly, even if not in frequent use, to maintain battery health. Store batteries in a cool, dry place.
- Storage: When not in use, store the headsets in their protective case to prevent damage from dust, moisture, and impacts.
- Microphone Windshield: Replace the micro windshield periodically to ensure optimal audio clarity and hygiene.
- Water Resistance: While the headset is water-resistant, avoid submerging it in water or exposing it to heavy rain for prolonged periods. Dry thoroughly if it gets wet.
Troubleshooting
- No Audio / Intermittent Connection:
- Ensure all headsets are powered on and fully charged.
- Verify that all headsets are correctly paired according to the "Setup and Pairing Guide."
- Check the distance between headsets; ensure they are within the 500m operating range. Obstacles like thick walls can reduce range.
- Restart all headsets in the correct sequence (Master, then Level One, then Level Two).
- Try activating "Boost Mode" on the Master headset to enhance signal strength.
- Poor Audio Quality / Noise:
- Ensure the microphone windshield is properly installed and clean.
- Verify that the Acoustic Echo Cancellation (AEC) feature is active.
- Check for strong electromagnetic interference in the environment.
- Adjust microphone position for optimal voice pickup.
- Headset Not Turning On:
- Ensure the battery is correctly inserted and fully charged.
- Check the power switch position.
- Difficulty Pairing:
- Ensure you are following the long-press durations for Button A precisely as described in the "Setup and Pairing Guide."
- Confirm that only the necessary headsets are in pairing mode at each step.
