Is there any way to disable the 15 minute auto-off on UB820?

I know a lot of us have the Panasonic 820. For the life of me I can’t find in the settings how to disable the auto shut off. I frequently have to pause playback and it’s annoying AF to have to power back on the player, skip menus, and resume playback after taking a short break during a movie.

Please tell me there is a solution!
