I have a 6x16 KSU that looses ALL settings when the power fails. Yes, we have a UPS hooked up, however if the UPS is turned off in error, or an extended power failure happens and the UPS battery is drained, then the KSU has to be reprogrammed as if it was a brand-new install. Is there a CMOS battery or something similiar that can be replaced to retain programming on this KSU incase the power to the unit is lost? Thank you.
