I just got a used APC Back-UPS 300 and somewhere it says that it is
for computer equipment only and not for medical equipment.

I had hoped to use this for my heart-lung machine, but since I can't
do that, can I back up a Philips DVDR and a couple clock radios with
it, even though those are not computer equipment?


(Another weakness of the Philips 3576H DVDR is that it forgets all the
planned recording times if it's without power for more than a minute
or two.)
