out of my realm of knowledge.
M.B. in New Jersey maintains two (2) "technical" experts [to
replace the one before, named Jonathan Papiyatro, if he did
not know the answer he'd find someone who did !] You can
call Toll Free ! 1-800-222-0100 and someone will plug you
into the "techs" voice mail .

OR , Gather up your courage, (you are an Amerikaner) and
CALL...
Deutchland direct , they all speak better english than we
do ! And I get the impression (at least in Sindelfingen ) a
call from the U.S. gives them something to guffaw about
over their steins.
