A:Answer Hi Jack, thanks for contacting Sony!
We can confirm that with the PS-LX310BT turntable, the tone arm automatically returns to its rest position and the platter stops rotating once a record has finished playing.
For more detailed information and to see the complete features of your turntable, you can refer to the product manual. You can find it here: https://www.sony.com/electronics/support/res/manuals/4748/2a8f06044efec02b753eff3df707fb93/47487551M.pdf
We appreciate you choosing Sony.
Best regards, Gus, Sony Social Media Team
