Maintenance

• Microphone Care: Do not remove the sponge cover from the microphone, as it helps reduce noise and ensures clear sound.
• Feedback Prevention: To effectively avoid howling, maintain a distance of at least 50 cm (20 inches) between the microphone and the amplifier. Also, keep the front of the amplifier at a distance of 50 cm or more from any walls or reflective surfaces.
• Battery Lifespan: To ensure the battery's longevity, fully charge the amplifier when it is not in use for a long period.
• Interference: Keep the amplifier away from charging devices or other electronic devices to avoid potential interference.

Troubleshooting

• No Sound: Ensure the amplifier is turned ON and the volume is adjusted. Check if the microphone is securely plugged into the MIC-IN port.
• Howling/Feedback: Increase the distance between the microphone and the amplifier (at least 50 cm). Ensure the microphone's sponge cover is in place. Keep the amplifier away from walls or reflective surfaces.
• Distorted Sound: Adjust the volume to a lower level. Ensure the microphone is positioned correctly (0.5-1 cm from mouth) and not too close to the amplifier.
• Device Not Charging: Verify that the USB-C cable is properly connected to both the amplifier and a standard 5V power source. Check the indicator light for charging status. Avoid using quick chargers.
• Short Battery Life: Ensure the device is fully charged before use. For prolonged storage, fully charge the battery to maintain its lifespan.
