How do I connect the BIGFUN Electronic Keyboard to a PC?
Based on the BIGFUN Electronic Keyboard (BF-420) manual, the USB connection to a computer is primarily intended as a power source rather than a MIDI or data interface. Here is how to connect it:
If the keyboard is not turning on when connected, ensure the USB cable is tightly plugged in at both ends and that your computer's USB port is active.
Note: Pour nos utilisateurs francophones, le manuel indique que la connexion USB au PC sert principalement d'alimentation électrique (5V, 1000mA). Il n'est pas précisé si ce modèle supporte le transfert de données MIDI.

How do I use the recording function on the BIGFUN Electronic Keyboard, and what does the AF display mean?
Based on the BIGFUN BF-420 manual, here is how to operate the recording and playback functions:
Regarding the "AF" display: The provided manual does not explicitly define an "AF" code. However, in many electronic keyboards, "AF" can appear during the recording process or may indicate a specific mode. If the sound is distorted while this is displayed, ensure you are using a high-quality DC 5V / 1000mA power adapter, as the manual warns that inferior cables and adapters can cause noise and malfunctions. Additionally, ensure the keyboard is not near a TV or radio, as this can cause audio interference.
If your recording still does not play back after following these steps, try pressing the STOP button before pressing PLAY to ensure the recording session has ended.

How do I fix it?
How do I fix the tuning on my Bigfun BF-730A2 keyboard if it is shifted by a half tone?
Based on the available documentation for BIGFUN electronic keyboards, there is no manual calibration or tuning adjustment feature provided for users. These keyboards are typically pre-set at the factory and do not include a "Transpose" or "Fine Tuning" function in their standard control sets.

My kid loves it but should the record function works with the microphone?
Does the record function on the BIGFUN Electronic Keyboard record audio from the microphone?
