Star wars millenium falcon vintage toy from 80's?

Question

doe anyone know how to activate the sound effects. I have found 4 buttons on the side by the batterie compartment but only 2 of them work. the millenium makes a roaring noise and all its lights light up - very occassionally when moved.

all in all not bad for a toy thats as old as me!

is there any other buttons I should be aware of? Time ages my brain! It took me the best part of an hour to find these 4!

thanks

Sounds more like a loose wire to me
