Pull up the small cover plate for the "remote control start/stop" plug allocated at the backside. It is fixed with double-sided adhesive tape

For turning around the turntable put maybe two books beside the main axis . So that the device is not resting at the main axis either then the tone arm!

Loosen 8 screws with a Phillips screwdriver at the bottum of the turntabel. (signed red in picture).

Be aware that under every screw a spacing ring is allocated, the will fall away while opening the housing. (It is not a big problem during reassembling later)
