Right. I should have made that clearer. The way it works is that AC
power lose is detected and generates an error condition that can be
detected using an "On error xx. Goto yyyy" type statement in the user
program. Upon meeting that condition, the user can have the program jump to
any desired subroutine that does what ever file saves and shut down
procedures are necessary. Obviously the battery must keep the machine
running for some period of time for this to happen so it is a sort of UPS.
The manual doesn't say how long the battery will keep the machine running
but clearly they expect you to save your data and shut the system down as
quickly as practicle.
