5. Setup Instructions

5.1. Attaching the Transmitter to the Violin

1. Locate the spring clip on the VT-5 Transmitter.
2. Carefully slide the spring clip onto the violin, typically near the f-hole or bridge, ensuring a secure fit without damaging the instrument.
3. Adjust the 360-degree soft tube to position the condenser microphone towards the f-hole of the violin for optimal sound capture.

5.2. Connecting the Receiver

1. Plug the 6.35mm jack of the RE-10 Receiver directly into a mixer, amplifier, or active speaker.
2. Ensure the connection is firm.

6. Operating Instructions

6.1. Powering On/Off

• **To Power On**: Press and hold the Power button on both the Receiver (RE-10) and the Transmitter (VT-5) until their respective indicators light up.
• **To Power Off**: Press and hold the Power button on both devices until the indicators turn off.

6.2. Pairing and Channel Selection

The system uses IR sync for easy pairing and channel selection:

1. Power on both the Receiver and Transmitter.
2. On the Receiver, press and hold the '+' or '-' buttons until the channel letter (e.g., 'F') starts blinking on the LED display. This indicates it's in channel selection mode.
3. Use the '+' or '-' buttons to select your desired channel.
4. Once the channel is selected, slide the SYNC switch on the Receiver towards the right (IR sync).
5. Align the IR sensor on the Receiver with the IR sensor on the Transmitter. The green RF indicator on the Receiver will light up, confirming successful pairing.
6. To lock the channel, slide the SYNC switch on the Receiver back to the left.

6.3. Usage

Once paired, the system is ready for use. Ensure the microphone is positioned correctly to capture the violin's sound. The system is designed for various scenarios including solo performances, accompaniment, self-play, and group performances.

7. Charging Instructions

Both the Receiver and Transmitter are powered by built-in 3.7V Lithium batteries. Use the provided charge cable and adaptor to charge the devices.

1. Connect the USB charging cable to the adaptor.
2. Plug the adaptor into a power outlet.
3. Connect the micro-USB ends of the charging cable to the charging ports on both the Receiver and Transmitter.
4. The charging indicator lights will illuminate, indicating that the devices are charging.
5. A full charge provides over 6 hours of continuous use.

8. Maintenance

• Keep the microphone system clean by wiping it with a soft, dry cloth.
• Avoid exposing the devices to extreme temperatures, humidity, or direct sunlight.
• Store the system in its protective carrying case when not in use to prevent damage.
• Do not attempt to disassemble or repair the devices yourself, as this will void the warranty.

9. Troubleshooting

• **No Sound**: Ensure both the Receiver and Transmitter are powered on and successfully paired (green RF indicator on Receiver). Check all cable connections to the mixer/amplifier. Verify the volume levels on all connected audio equipment.
• **Interference/Poor Sound Quality**: Try changing the channel on the Receiver and re-syncing with the Transmitter. Ensure there are no obstructions between the Transmitter and Receiver. Keep other wireless devices away from the system.
• **Feedback (Microphony)**: The system is designed to minimize feedback. If feedback occurs, try reducing the gain on your amplifier/mixer, repositioning the microphone slightly, or moving further away from the speakers.
• **Short Battery Life**: Ensure both devices are fully charged before use. Battery life is approximately 6 hours of continuous use.

10. User Tips

• The system is highly intuitive and easy to set up, even for users who are not highly technical.
• The compact size of the components makes them very convenient for transport and use.
• The microphone effectively captures the violin's sound with good clarity, even when not placed extremely close to the instrument.
• The system features a 'no sound burst' function, preventing sudden loud noises when connecting or disconnecting, which is a significant improvement over older systems.
