4. Maintenance
4.1 Charging
The microphone transmitters and receiver are charged via the provided charging case and Type-C cable. Ensure the units are properly seated in the charging case. The charging case itself is charged via a Type-C port.
4.2 Wind Muff Installation

5. Troubleshooting
5.1 Microphone Not Connecting/Pairing
- Ensure both the transmitter(s) and receiver are fully charged.
- Verify that both units are powered on.
- Check if the indicator lights are solid after powering on. If they are flashing, the units are still attempting to pair.

5.2 No Sound or Poor Sound Quality
- Ensure the receiver is securely connected to your recording device.
- Check the volume settings on your recording device.
