Do you know that for sure or could it be some type of non-volatile memory?
That Dittle FSG71M has a built-in Lithium battery for it's memory which is
soldered into the PC board and looks like a capacitor. Dittle recommends
changing every 5-6 years. Not a job for amateurs.

The 302 manual makes no mention of an internal battery, so I assume there
is no need to change it. I don't know how they handle trashing the

There is an internal long-life lithium battery, it just doesn't need to be
replaced on a routine basis. Eventually, I suspect, it will need
replacement (perhaps after 10 years or so), in which case the 302 will
need to be returned to Cambridge or one of its agents...
