Magnavox CD transport screws-how to use?

Hi all... I am looking to purchase a cdb six disc Magnavox player and it looks like from the picture there are three transport screws. Does anyone know how these are placed for transport? Not sure if you remove them from their current location and place them in the two holes that are diagonal from each other on the back?

THanks much!

Sure look like transport screws. They are usually underneath the unit. But they certainly look like them.

I never ship CD players. local pick up only. Magnovox CDB 650 that everybody wants I sold to a guy in New York, and his son drove down to pick it up.
$2, and six bux for a power cord. He paid $200.
