I have a Jandy Aqualink PS-4 that resets the time and date about every 3-4 days. I have changed the 9v battery and changed the channel from 9 to 7 and back. The PDA frequently has trouble syncing at certain times of the day, typically during midday. My main concern is the time. I realize the time is kept by the panel, not the PDA, but it has done this on and off over the years with or without a new 9v battery. Is there a jumper fix or wiring trick that will help this thing tell time? Any help here would be appreciated.
