If available, use the Therapy Port nut socket to unscrew the large nut on the back of the Therapy

Do not use pliers with sharp teeth because if they slip, they can create small metal shavings trapped
inside the box that may affect performance of your HeartStart XL+.

and washer. Turn the 9-pin connector so it passes through sideways.
