> Looses it's exec. on a regular basis.Yup, and I know why. There is a double pole switch on the battery
charger - says battery on/off. One pole connects 110 V AC to
the battery charger, the other connects the battery's 12 V DC to
the pepory backup power supply. I think the 12 contacts go
open circuit about every 2 - 4 weeks in humid conditions. You

to come up unless I flipped that switch off and back on.
