Setup Instructions
- Positioning the Pedal: Place the sustain pedal on a flat, stable surface in front of your digital piano, MIDI keyboard, or synthesizer. The anti-slip footpads on the bottom of the pedal are designed to prevent movement during use.
- Connecting to Your Instrument: Locate the 1/4-inch (6.35mm) sustain pedal input jack on your instrument. This is typically labeled "Sustain," "Damper," or a similar indicator. Insert the 1/4-inch plug from the pedal's cable firmly into this jack.
- Adjusting Polarity: The pedal features a polarity reverse switch (often labeled "Performance switch" or similar) located on the side of the unit. If the sustain effect is reversed (e.g., notes sustain when the pedal is up and stop when pressed), flip this switch to the opposite position. This ensures compatibility with various instrument brands and models.
- Testing: After connecting and adjusting the polarity, play a few notes on your instrument and press the sustain pedal to verify that it functions correctly.

Operating Instructions
The TenYua Universal Sustain Pedal operates like a traditional piano sustain pedal, allowing notes to continue sounding after the keys are released.
- Engaging Sustain: Press the pedal down with your foot to activate the sustain effect.
- Releasing Sustain: Lift your foot from the pedal to disengage the sustain effect, allowing notes to decay naturally.
- Polarity Switch: As mentioned in the setup, if the sustain effect is inverted, use the polarity switch on the side of the pedal to correct it. This ensures the pedal functions as expected with your specific instrument.

Maintenance
To ensure the longevity and proper functioning of your sustain pedal, follow these simple maintenance guidelines:
- Cleaning: Wipe the pedal with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the finish.
- Storage: When not in use, store the pedal in a clean, dry environment, away from extreme temperatures and direct sunlight.
- Cable Care: Avoid sharply bending or kinking the cable. Store it loosely coiled to prevent damage.
- Inspection: Periodically check the cable and plug for any signs of wear or damage.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sustain effect is reversed (notes sustain when pedal is up, stop when pressed). | Incorrect polarity setting for your instrument. | Locate the polarity reverse switch on the side of the pedal and flip it to the opposite position. |
| No sustain effect when pedal is pressed. |
|
|
| Pedal slides during use. | Insufficient grip on the floor surface. | Ensure the pedal is placed on a clean, dry surface. The anti-slip footpads should provide adequate grip on most surfaces. For very smooth floors, a non-slip mat may be used. |
