Ademco 4219 how to open

I am ugrading my alarm panel a Vista-20SE to a Vista-20P. It currently has a 4219 expansion module. I would like to open it to check the settings and possibly resistors, but I don't see a tab to push to open it and the documentation does not state how to open the actual box. I don't want to try to pry it open and break a tab if one has to be pushed, can anyone help.

It has a couple of small notches for a flat screwdriver tip on the edge of the cover. There may or may not be a small screw (it's optional) as well. Don't be brutal. The plastic does get brittle with age.

My 4229 has a similar case. The new ones have no external tabs or screwdriver slots. The cover just pops off by pulling hard on the long slot on the bottom edge. I thought I was going to break the cover too. After getting the cover off, this appears to be the only way. Good luck!
