If you encounter any issues with your keyboard, please refer to the following common problems and solutions:
- Ei virtaa: Ensure the power adapter is securely connected to both the keyboard and a working power outlet. If using batteries, check that they are correctly inserted and not depleted.
- Ei ääntä: Check the volume level. Ensure headphones are not connected if you expect sound from the speakers. Verify that a sound (Timbre) is selected.
- Näppäimet eivät vastaa: If only certain keys are not responding, try gently cleaning around the keys. If the entire keyboard is unresponsive, try turning it off and on again.
- Vääristynyt ääni: Reduce the volume. Ensure the microphone is not too close to the speakers, causing feedback.
If the problem persists after attempting these solutions, please contact McGrey customer support for further assistance.
