Welcome to my teardown of an old Panasonic wireless phone. I have no idea what the model is.

Slide off the back cover as shown in the first picture. Then remove the batteries. (They come out the same as AAA batteries)

Remove the two circled screws.

Be a little aggressive with the case when prying the phone apart. Squeeze the small metal thing securing the speaker to the case.

Pull off the board, then remove the circled earpiece speaker. Thank you for reading.
