module slots are numbered as follows.

Ensure the codec is not powered up when inserting or removing modules. Where possible
use anti-static precautions to help minimize the chance of static charges damaging the
highly sensitive circuitry. Do not force a module into the codec. Modules should be
installed slowly and gently.
1. Remove power from the codec and then remove the 4 screws from the blanking panel or module

2. Carefully slide the new module into the module slot and ensure the base of the module remains

inside the codec. Remove the module and reinsert it carefully to resolve this issue.
