4. Remove the controller from the appliance:
a. Put on an ESD wristband or take other antistatic precautions.

cables.
c. Release the controller from the appliance by squeezing the latch on the cam handle until it
releases, and then open the cam handle to the right.
d. Using two hands and the cam handle, slide the controller out of the appliance.
Attention: Always use two hands to support the weight of the controller.
e. Place the controller on a flat, static-free surface with the removable cover facing up.
f. Remove the cover by pressing down on the button and sliding the cover off.
5. Remove the battery from the failed controller, and install it into the replacement controller:

to go off before removing any components.
