2. Setup Instructions
2.1 Attaching the Microphone Transmitter to the Violin
- Carefully open the clip on the microphone transmitter unit.
- Attach the clip securely to the edge of your violin, ensuring it does not obstruct playing or damage the instrument's finish.
- Adjust the flexible gooseneck of the microphone to position the microphone head optimally for sound capture, typically near the f-hole or bridge.

2.2 Connecting the Receiver
- Locate a 6.35mm (1/4 inch) input jack on your mixer, amplifier, or active speaker.
- Plug the VT-5 receiver directly into this input jack. Ensure a firm connection.

2.3 Powering On and Pairing
- Press and hold the power button on both the transmitter and the receiver until their respective indicator lights illuminate.
- The system features IR sync for automatic frequency downloading from the receiver. The units should automatically pair.
- If pairing does not occur automatically or if you experience interference, you can manually select one of the 16 pre-set frequencies on both the transmitter and receiver to find a clear channel.

3. Operating Instructions
3.1 Basic Operation
- Once paired, the system is ready for use. Ensure the volume on your connected mixer or amplifier is set appropriately.
- The digital ID code technology helps to completely solve frequency interference, providing a stable and clear audio signal.
- The portable design allows for freedom of movement, making it ideal for stage performances, street performances, and other dynamic settings.
3.2 Using Multiple Systems
If using multiple VT-5 systems simultaneously, ensure each system is set to a different channel to prevent interference. The system offers 16 selectable frequencies for this purpose.

4. Maintenance
4.1 Charging the Battery
- The transmitter and receiver are powered by 3.7V lithium batteries.
- Connect the provided USB charging cable to the charging ports on both units and a suitable USB power source.
- A full charge provides over 6 hours of continuous use. Charge the units when the battery indicator lights show low power.
4.2 General Care
- Keep the units clean and dry. Avoid exposure to extreme temperatures, moisture, or direct sunlight.
- Do not attempt to disassemble or modify the units, as this will void the warranty and may cause damage.
5. Troubleshooting
No Sound Output
- Ensure both the transmitter and receiver are powered on and fully charged.
- Verify that the receiver is correctly plugged into the audio input of your mixer/amplifier.
- Check that the selected channel on the transmitter matches the channel on the receiver. Adjust if necessary.
- Confirm that the volume on your mixer/amplifier is turned up and not muted.
Interference or Poor Sound Quality
- Change the operating channel on both the transmitter and receiver to avoid interference from other wireless devices.
- Ensure the transmitter and receiver are within the optimal operating range (up to 60m line-of-sight). Obstacles can reduce range.
- Check for any strong electromagnetic interference sources nearby.
Short Battery Life
- Ensure the units are fully charged before each use.
- Battery performance may degrade over time with repeated charging cycles.
