Two Sound Modes
1. There is a button inside the door for two modes choosing.
2. In ''beeps sound'' mode, when you press the digital button you will hear the sound like ''du''. If the password is wrong, you will hear the sound like ''oh''.
3. In ''voice'' mode, when you press the digital button you will hear the sound like ''password please''. If the password is wrong, you will hear the sound like ''oh sorry, please try again''
4. If you don't like the music or the sound is too loud for you, we suggest you choose the beeps sound mode.
