Don't know whether to top post or bottom post - but I don't care for
being described as "part of the problem". You do not know the
situation or the background and that comment is unfair and disturbing
. People have priorities driven by personal situations - that system
was installed 3 days after I left hospital - 30 days later I was back
in thru the ER and was on edge buying the farm for another week - and
am now faced with possibly facing same situation again . Some spurs
every 18 khz are sure as hell not my biggest concern at this point
have they been for past year.
I was just answering the question of specific manufacturer model
numbers that have exhibited an issue.
