A couple of things -
1. The instructions I gave above are for a RS125. As I understand the RS120 has the battery soldered or sonically welded in.
2. I found the installation manual, here it is in english:

Here is the area with all of the GPS sensor manuals & drawings in various languages:

3. If your RS125 is pole mounted like mine, it shouldn't have the foam gasket per the installation manual. The foam gasket is only for flush mounting.
