I have the Jandy AquaLink RS, with interface - PDA system. Like others, my PDA is stuck on waiting. I tried to reset the channel and the PDA will not get out of the learn mode. I am assuming my problem is the J-Box because I turned off the power and removed the 9V battery and am still having the problem. I have read your links and am not sure if I can simply buy a new J-Box or do I need to up grade to the iAquaLink system?
