Steve,
There are much better devices out there than SPOT for what you are looking for. SPOT may be limited in it's indoor functionality. Might be good for out doors, for on the daily walk while away from the house or something, (If used in the tracking mode) but on SPOT (not SPOT II) the buttons are not covered, just may be confusing.
Try google for Life Alert, or
Lifeline. I used to install "LifeLine" and it is a pretty foolproof system. Daily activity timer, and speaker on phone capability, (like ON STAR), and now they have a fall alert also. The monthly fee will be higher than SPOT, but it will be more of what you want.
I believe that most of their system is now monitored in a call center type base, but they do have a tiered response system, so that 911 is not necessarily the first call out. CAn be a neighbor, or you, or another friend, or depending on the alarm response -- 911.
As a disclosure, I used to install them when I worked for a small hospital in a rural community in Oregon. That was 25 years ago, and though I think the system is a good one, I have no financial interest there.

Also might check with your local Senior Services Center, Fire Rescue EMS Department, hospital social services, or a local Medical equipment provider such as Lincare may be able to point you in a good direction.
