Once again thank you for all your replies, however, would be nice to be given the correct procedure, rather then people saying "they think " this is what they would do, I have never had to address this problem within my club, but would like to know what to do, as and when it occurs, as it surely will, and I for one, do not want to be responsible for loosing members data, or giving out, an incorrect velocity, Yet again I ask any UNIKON Reps. out there, if they can clarify this procedure? Thank you.
