Setup Instructions

1. Charge the Receiver: Connect the receiver to a USB power source using the provided USB-C charging cable. The indicator light will show charging status. Ensure it is fully charged before first use.
2. Insert Microphone Batteries: Unscrew the bottom cap of each microphone and insert two fresh AA batteries (not included), observing polarity (+/-). Replace the cap securely.
3. Power On Microphones: Press and hold the power button on each microphone until the digital display illuminates. The display will show the battery level and a channel number (e.g., CH-3).
4. Power On Receiver: Press and hold the power button on the receiver until its indicator light turns on.
5. Connect Receiver to Audio Device: Plug the 1/4" TS plug of the receiver directly into a microphone input jack on your amplifier, mixer, or PA system.
6. Automatic Pairing: The microphones and receiver are designed to pair automatically. Once both are powered on and within range, the receiver's indicator lights for the respective channels should show a stable connection. The microphone display will also confirm the active channel.
7. Adjust Volume: Set the volume on your audio device to a low level initially, then gradually increase it to a comfortable listening level.

Operating Instructions

• Using the Microphones: Hold the microphone approximately 2-6 inches from your mouth for optimal sound capture. Avoid covering the microphone head with your hand, as this can affect sound quality and signal.
• Channel Selection: The system typically auto-selects clear channels. If interference occurs, you may be able to short-press the power button on the microphone to cycle through available channels. Ensure the receiver also adjusts to the new channel, or manually select it on the receiver if it has such a feature (refer to your audio device's manual for input channel selection).
• Battery Indicator: Monitor the battery level displayed on the microphone. Replace batteries promptly when low to avoid interruption. The receiver's indicator lights will also signal low battery or connection status.
• Range: Maintain a clear line of sight between the microphones and the receiver for best performance. Obstacles can reduce the effective wireless range.

Maintenance

• Cleaning: Use a soft, dry cloth to clean the microphones and receiver. Do not use liquid cleaners or solvents.
• Storage: Store the system in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries from microphones if storing for extended periods to prevent leakage.
• Battery Care: For the rechargeable receiver, avoid overcharging. For microphones, use high-quality AA batteries and replace them as needed.

Troubleshooting

• No Sound:
  • Ensure microphones and receiver are powered on.
  • Check microphone batteries.
  • Verify the receiver is securely plugged into the audio device's microphone input.
  • Increase the volume on your audio device.
  • Confirm microphones and receiver are paired (check indicator lights/displays).
• Poor Sound Quality/Interference:
  • Move closer to the receiver.
  • Ensure no obstructions between microphone and receiver.
  • Try changing the microphone channel.
  • Check for other wireless devices operating on similar frequencies nearby.
  • Ensure microphone batteries are not low.
• Microphone Not Pairing:
  • Power cycle both the microphone and receiver.
  • Ensure they are within effective range.
  • Check microphone batteries.
