If no license key is installed at all, you can skip step 3 of the following description:
1. Switch off the equipment.
2. Loosen the four mounting screws and pull out module of type P4LT/P4LU.
3. Removal of the installed license key:
Limit deflection of socket latches to just free the iButton edge from retained state. Avoid
applying excess force to latches. The socket is shown in Figure 1.
4. Insertion of the new license key:
Apply appropriate back pressure at the opposite side of the P4LT/P4LU printed circuit board
before the license key is inserted into the socket.

iButton. The socket is shown in Figure 1.
