5. Operating Instructions

5.1 Power On/Off

Press the power button on the receiver to turn it on or off. For microphones, use the ON/OFF/MUTE switch located on the microphone body.

5.2 Automatic Frequency Scan

To find the clearest available frequency, press the 'MENU' button on the receiver to access the auto-scan function. The system will automatically search for and select an optimal frequency from 100 selectable channels for each microphone. Once a frequency is selected, use the IR sync function to pair the microphone with the receiver by aligning their IR sensors.

6. Maintenance

• Battery Replacement: Replace microphone batteries (4 AA per mic) when the battery indicator shows low power to ensure optimal performance and prevent unexpected shutdowns.
• Cleaning: Use a soft, dry cloth to clean the receiver and microphones. Avoid using liquid cleaners or abrasive materials.
• Storage: When not in use for extended periods, remove batteries from the microphones and store the system in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

• No Sound or Low Volume:
  • Ensure the receiver and microphones are powered on.
  • Check battery levels in the microphones and replace if low.
  • Verify all audio cables are securely connected between the receiver and your external audio equipment.
  • Adjust volume levels on both the receiver and your external audio equipment (mixer/amplifier).
• Interference or Dropouts:
  • The system offers 100 selectable frequencies per channel to avoid interference. Use the automatic frequency scan feature to find a clear channel.
  • If interference persists, manually select a different channel.
  • Ensure a clear line-of-sight between the microphones and the receiver, avoiding large metal objects or other wireless devices that may cause interference. The optimal working range is 180-240 feet (60-80 meters) line-of-sight.
• Microphone Not Pairing:
  • Ensure the microphone's IR sensor is aligned with the receiver's IR sensor during the pairing process.
  • Repeat the auto-scan and pairing steps carefully.
