Maybe I'm overlooking it but I cannot find a way to lower the volume of the on-board speaker when I play back a recording. Neither on the cam, nor in the menu, nor in the manual. Does anybody know if it is possible?

It's the little wheel on the back of the camera, just left of the battery compartment door.

Hi Kees,

Try the menu scroll switch at the back of the camera.

Best regards,

Robert
