Motorola TPG2200 Tetra Pager Battery Cover with Clip and RFID Chip cavity for identification or lock systems.
For removing the cover you need to use a small screwdriver or similar und pry the cover down from the pagers body carefully.
The Pager will not fit into the home station if this cover is installed!
The clip should be printed on its side for increased rigidity. The hole and the clip are 14mm, so it is a very tight to pressfit. You might consider to decrease the height of the clip a little bit to make the assembly easier.
