I have a Jandy Aquilink RS control system that uses a PDA to control start and stop times (and other programming). Occasionally I want to use the PDA to modify a program, but the PDA is not linking up. So I go to the Jandy Antenna box, take the 2 screws out to access the board, Hold the up and down button on the PDA and have it relearn the channel. I have tried several channels but with the same result. Loss of contact within a day or so.

Asked my pool builder to contact Jandy, the response was to use a higher channel number. Didn't work...same result.
