- Anti-Howling Feature: The system incorporates intelligent anti-howling technology to minimize feedback during use.
- Signal Range: The system offers strong reception capability with a transmission distance of up to 100 feet (approximately 30 meters) in optimal conditions. Maintain a clear line of sight between the microphone and receiver for best performance.
- Monitoring Battery Life: The microphone's LED display shows the current battery level. Recharge the batteries when the indicator is low.
5. Maintenance
- Charging: The built-in 800mAh batteries provide 4-6 hours of use. A full charge typically takes 3-4 hours. Use the provided USB cable for charging.
- Cleaning: Wipe the microphone body and receiver with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners. For the microphone head, gently remove the foam cover and clean as needed.
- Storage: Store the microphone system in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
- Battery Care: To prolong battery life, avoid fully discharging the batteries frequently. Recharge them regularly, even if not in constant use.
6. Troubleshooting
