Group,

Thank you for all the responses. For those that questioned the purpose of
this timer... Its to control an automatic emergency telephone dialer set to
activate at say 12 noon each day unless deactivated before noon. Its a dead
man's device for an invalid living alone. I'll also add a second audible
alarm to activate as say 11:O'clock to remind the user to deactivate the
dialer activation set for noon each day. The system needs to be as dummy
proof as possible.
