Check all cable connections and ensure the receiver is plugged into the correct audio input on your device. Verify the volume levels on both the microphone system and your audio device.
• Interference/Poor Sound Quality: Move closer to the receiver to ensure you are within the 165ft range. Avoid obstacles between the transmitter and receiver. Check for other 2.4G wireless devices nearby that might cause interference. Ensure the wind muff is properly installed if experiencing wind noise.
• Battery Not Charging: Ensure the charging cable is securely connected to both the devices and a power source. Check if the power source is active.
• Microphone Not Picking Up Sound: Ensure the external 3.5mm lavalier microphone is fully plugged into the transmitter. If using the built-in microphone, ensure it is not obstructed.
