The three LEDs in front of the drawer indicate if the laser is active, if the player is on standby and if the play mode is on pause ; the green LEDs to the right indicate the selected programmed tracks, the lower row indicate which track is currently playing or how many tracks are available on the cd.

The CD logo at the far right is normally back-lit in blue!
