The USER interface is just a display board with tactile push button switches. There aren’t any

processors contained on this board.

There is a ferrite bead that the harness connecting the boards wraps around to minimize Electro-

Magnetic Interference (EMI).

Three screws secure the User Interface/Control assembly to the chassis. Once removed, the control

slides to the right.

Three tabs secure the User Interface board to the control assembly.
