Encoder says NIL

I have a socalled encoder & decoder, bought from Amazon UK. Their
title is
Transform Your Records Cassettes Cd Vinyl to Mp3 Format.. Encoder - Decoder

by sec

No Transform Your Records Cassettes Cd Vinyl to Mp3 Format.. Encoder - Decoder

by sec

Now the beaut little gadget says NIL on its small screen when I try to encode music.
The manual doesn't mention this condition, and I can't find the outfit "sec" who
presumably makes it.

What does NIL mean? How do I get back to normal function?

Thank you.

 

NIL means "nothing" so it probable means it can't detect any input to the device.

On the link you posted there's a picture of the back of the device and it looks like you should have the switch set to AUX and your player plugged into AUX IN.

 

Thanks, but that is the case. It's on AUX etc.
