Hello,

Several years ago I bought an A149-1 second hand and this was not working as
described in the manual.
I remember I solved this problem by reading the manual section about the
test-mode jumper.
I don't remember how the module acted with the jumper in the wrong place (so
this might be irrelevant info).
But maybe it is an idea to check it before doing anything else.
