Dear Mister
I have a VSS 4500-X, this equipment is funcioning OK. The enviroment variables are rigth. No doubt about that.
But, in the near past time, the equipment start to give a whistle sound. Never heard something like that.
What could it be??? I can open a Case, because the variables are ok. But we have the doubt, because we and our customer thing that the equipment will fail in the next future.
Some guys has the same behavior??
Best Regards
