Help Scheduled Airplane Mode

[SamsungDiane]

I have a Samsung Galaxy A51 which I set to automatically Airplane Mode from 1-5 a.m. but I want to change it back. I don't remember how I did it and can't figure out how to undo this action. Anybody know how this is done? I feel like it's a battery saving technique but I'm not finding it.

I think page 81 may help.

Not sure, because I don't have the device, and I could not view the page on the site.

You may have better luck if you download the manual {it's free} and read it with a PDF reader.
