Questions about Lenco Scd-550

Should be in the operating instructions (https://www.manualslib.de/manual/213951/Lenco-Scd-550.html?page=5#manual)

In CD mode, the display is always lit. Only the side lights and the elongated light above the display can be switched off/on.

I don't think so, but I can't say 100% because it was a gift. I guess Bluetooth is only possible for music.

I never had a radio with an alarm function 😅 I think that's rather rare

The disco effect can be switched off, but not the light itself. You can set the radio to light up only in one colour instead of changing colours.
