Touch Sensitivity

The semi-weighted keys are touch-sensitive, meaning the volume and timbre of the sound will vary based on how hard you strike the keys, mimicking an acoustic piano. This feature can often be adjusted or turned off via the 'Function' button and corresponding key.

Maintenance

Proper care will ensure the longevity and optimal performance of your digital piano:

• Cleaning: Use a soft, dry cloth to wipe down the surface of the keyboard. For stubborn dirt, a slightly damp cloth can be used, followed immediately by a dry one. Avoid abrasive cleaners, solvents, or waxes.
• Key Care: Keep the keys clean and free from dust. If using keynote stickers, ensure they are applied and removed carefully to avoid residue.
• Storage: When not in use, store the piano in a cool, dry place away from direct sunlight, extreme temperatures, and humidity. If storing for extended periods, consider covering it with a dust cover.
• Handling: Always handle the keyboard with care. Avoid dropping it or placing heavy objects on top of it.
