Wow!
Thankyou all for your replies. I will try your suggestions this afternoon and try to get it sorted. Am not very technically minded but what I lack in ability is usually compensated for in tenacity :-) (Like a dog with a bone)
Will let you all know if I manage it, but if it takes a while ...worry not! I will be immersed in the manuals of said instruments. I intend to tell a responsible adult where I am going as I have heard tales of those who have gone into such manuals and have never been heard of again :-)
Thanks again
Tony
