I am using an Yamaha PSR-E423 Keyboard.

This is the User Manual

From the manual, I understand that we can power the keyboard through the AC Adapter or through 6 number of 1.5V batteries. (9V in total)

Suppose, If I connect both the AC Adapter and provide the battery power to the keyboard, which power will the keyoard use for its functions?

And in the event of power interruptions, will the keyboard continue if its battery powered?

    @Newbie I was also able to refund your rep that you spent on the bounty, so no worries there. – Cfinley Dec 30 '19 at 16:00
