Panasonic HC-VX981K Manual page 5

On the other side of where the main panel is, you will find the power input for the Panasonic.
Plug the AC adapter into it to recharge the Panasonic. We ask that when you are done with your
recordings, that you plug it into the socket. On the lower right hand corner, you will see an
attachment to plug in a pair of headphones to the Panasonic...so you can better hear the volume
as you record.
