She will do just fine, Deane. These devices have come a long way since the first ones were installed in 1962. Back then, the batteries only lasted 6 months at best and the entire unit had to be replaced--not just the batteries. Additionally, they were the size and shape of a hockey puck, whereas today's are tiny in comparison.
Good Luck, Old Friend,
Gary
