Thanks for that Tommy. Spoke to Unikon rep tonight, I have to send the members printout to Unikon,, he said as you have stated that his base station was powered down for more than 5 mins.. his set times and strike times were correct but because I had to enter his times manually into our results software I mistakenly put in the wrong master timer time and had his clcok an hour out...oops :( What concerened me was that when I first put his clock into the club base it said no rings arrived and when we went back to his loft and put the pocket clock into his own base the arrival times of his birds were there, then when I tried it in the club base once more the birds were all there but had all been given an arrival time of Wed 00-00-00hrs I then printed a race progress which gave the birds the arrival times that were on his own base but with SC4 on the printout. The week before this same members clock had the code LCM against each arrival but the club member who sees to this guys clock when he is offshore is adamant that he put the pocket clock in the base locked up his loft and left, not returning untill 30 minutes after the birds had arrived and the pocket clock had never been removed from the base at all. Lets hope Unikon can figure this one out as my brain is fried
