How to enter the self-diagnostic tests
To enter the self-diagnostic tests:
1. Within 2 seconds after turning the power on, press the top left key twice.
2. The keyboard should respond with six beeps, with the frequency increasing from low to high.
3. After one more beep, the keyboard is ready for the self-diagnostic tests.
