[Nfb-web] Olympus DS 50

[Steve Jacobson]

Bryan,

Room acoustics would generally not result in an echo having a delay of a second or more which is the reason for my concern, unless I am missing something here.  
As I have tried to say before, removing the microphone could well have solved the problem indirectly, though, but it may not always be an option.  I would want to 
understand the problem a little more to avoid future problems, but maybe you already do.
