If I play CDs without using the wallbox, why does it stop around the 2nd or 3rd song ?
The WP200e has a 9-minute guard, this is to prevent continuous CD playing if, for some reason, the CD changer decides to cancel the programmed play and enter full play mode. You can turn off the guard by pressing and holding the STOP key until the LED stops blinking then press and hold the POWER key until the LED starts blinking again.
