To begin with, we will disengage the back cover. To do this we introduce a flat tool between it and the frame and, making leverage movements, release the notches that hold it.

We remove the shield that covers the connector of the reader and we disconnect it to be able to separate the back cover.

Remove the eight Phillips screws (PH # 00) that hold the module and then disengage it.

We disconnect the coaxial cable and the interconnection cable from the auxiliary plate and then take it off the chassis.
