That's kinda what I thought. Each new pairing pushes the old one out. As for the reason why.... I was just thinking about redundancy. I have always carried a backup/2nd computer on OC. It's interesting to compare the two after a dive. With Oceanic, I can set the reciever code in the computers and see the same transmitter. I was just thinking about trying it with my Rebreather. Thanks for your help. FD
