2. Connect Receiver: Plug the 6.35mm male plug of the RE-10 Receiver directly into the input jack of your amplifier, mixer, or computer speaker.
3. Pairing (Frequency Synchronization):
   • On the RE-10 Receiver, press and hold either the Frequency Plus (+) or Frequency Minus (-) button until the channel letter on the LED display starts flashing.
   • Use the (+) or (-) buttons to select your desired channel (e.g., 'F').
   • Slide the SYNC switch on the receiver to the right to initiate the pairing process.
   • Hold the VT-5 Transmitter close to the RE-10 Receiver. The RF indicator on the receiver will turn green when successfully paired.
   • Slide the SYNC switch back to the left to lock the selected channel.
4. Attach Microphone to Violin:
   • Gently open the spring clip on the VT-5 Transmitter.
   • Carefully attach the clip to the edge of your violin, ensuring it is secure but does not damage the instrument.
   • Adjust the 360-degree soft tube to position the condenser microphone head near the F-hole of the violin for optimal sound capture.

5. Operating Instructions

Once the system is set up and paired, you can begin using it:

1. Ensure your amplifier or mixer is powered on and its volume is set to a low level.
2. Play your violin as usual. The microphone will capture the sound and transmit it wirelessly to the receiver.
3. Gradually increase the volume on your amplifier/mixer to your desired listening level.
4. The system offers stable signal transmission up to 50 meters in line-of-sight, allowing freedom of movement during performances.

The system provides stable signal transmission for long-distance reception, up to 50 meters.

6. Charging

Both the RE-10 Receiver and VT-5 Transmitter are powered by 3.7V Lithium batteries and can be charged simultaneously:

1. Connect the provided charge cable to the CHR port on the receiver and the charging port on the transmitter.
2. Plug the USB end of the charge cable into the power adapter.
3. Insert the power adapter into a standard electrical outlet.

• Its compact size is a significant advantage for musicians who need a portable and unobtrusive microphone solution.
• The microphone effectively captures the violin's sound with clarity, even without being placed extremely close to the instrument, and avoids harsh or noisy feedback often associated with wired systems.

10. Maintenance

• Cleaning: Use a soft, dry cloth to clean the surfaces of the transmitter and receiver. Avoid using harsh chemicals or abrasive materials.
• Storage: Store the microphone system in its provided hard case when not in use to protect it from dust, moisture, and physical damage.
• Battery Care: Charge the batteries regularly, even if not in frequent use, to maintain battery health and prolong their lifespan. Avoid fully discharging the batteries for extended periods.
• Environmental Conditions: Avoid exposing the devices to extreme temperatures, direct sunlight, or high humidity.

11. Troubleshooting

• No Sound Output:
  • Ensure both the transmitter and receiver are powered on.
  • Verify that the receiver is securely plugged into the audio input of your amplifier or mixer.
  • Check that the transmitter and receiver are successfully paired (RF indicator on receiver should be green).
  • Confirm that the volume on your amplifier/mixer is not muted or set too low.
  • Check the battery levels of both units and recharge if necessary.
• Interference or Poor Sound Quality:
  • Try changing the channel on the receiver and re-pairing the transmitter.
  • Ensure there are no major obstructions between the transmitter and receiver.
  • Reduce the operating distance between the transmitter and receiver (maximum 50m line-of-sight).
  • Check for other wireless devices operating on similar frequencies that might be causing interference.
• Microphone Not Attaching Securely:
  • Ensure the spring clip is correctly positioned on a stable part of the violin.
  • Adjust the flexible gooseneck to find a secure and optimal position for the microphone head.
