There is dirt and wear. I have confirmed that sound comes out of the AM/FM radio and CD. I cannot perform a detailed inspection because there are no instructions. If there are any overlooked or undiscovered malfunctions, please handle them yourself. It supports wireless playback via BluetoothR. It has a slim size with a depth of 65mm and is equipped with an 8cm speaker. It has CD repeat playback, random playback, and program playback functions. It has favorite station buttons for 4 AM and FM stations each, and also supports wide FM. Thank you for viewing.
