Controller Back Module
To install a separate controller back module, follow these steps:
- Turn off power to the frame (the frame cannot be operated during this procedure).
- Remove the top and bottom screws of the controller back module (leave the center screw in place), and then gently pull the back module out of its slot.
- Insert the new SELOPT-RR or SELOPT-RO back module, and then tighten the two screws provided.
- Turn on the power, and close the front panel to ensure proper cooling.
