Nor can you examine anything.
I don't consider these to be detrimental, but, as experience in these forums suggest, some of you will want this to be examinable. You're probably going to have to ring in a different box.

The moment that I know for sure, I'll advise accordingly.
Since this is your 2nd post of this question, be patient...everything will come to light soon enough ;-)
