Locate the battery compartment, typically on the back or side of the violin. Insert the required batteries (usually 9V, not included) ensuring correct polarity. Close the compartment securely.
Operating Instructions
1. Powering On/Off
Locate the power switch, usually near the control panel. Slide it to the "ON" position to power on the violin. Slide it to "OFF" when not in use to conserve battery life.
2. Adjusting Volume and Tone
The violin is equipped with a DV-10B pickup and controls for adjusting low, medium, and treble frequencies by +/-12dB. Use the dedicated sliders or knobs on the control panel to fine-tune your sound.
- Volume Control: Adjusts the overall output level.
- Tone Controls (Low, Mid, Treble): Allows you to shape the timbre of your sound. Experiment with these settings to find your preferred tone.
3. Tuning the Violin
The intelligent string plate is designed to facilitate easy tuning. Use a standard electronic tuner (not included) to tune the strings to their correct pitches (G, D, A, E from lowest to highest). Adjust the fine tuners on the tailpiece as needed.
4. Using the Piano Code Card Slot
The violin features a fixed position for the instrument code (often referred to as the bridge or piano code card slot). Ensure the bridge is correctly positioned for optimal sound and playability. Its fixed position is designed not to affect performance.

Maintenance
- Cleaning: Wipe the violin body with a soft, dry cloth after each use to remove rosin dust and fingerprints. Do not use abrasive cleaners or solvents.
- String Care: Replace strings when they become worn, dull, or difficult to tune.
- Bridge Position: Periodically check that the bridge is standing straight and is not leaning. Adjust gently if necessary.
- Storage: Store the violin in its case when not in use to protect it from dust, impacts, and environmental changes.
- Battery Replacement: Replace batteries when the sound becomes weak or distorted. Always dispose of used batteries responsibly.
