Abstract
A system for enabling a medical device. The system includes a cradle having a magnet for generating a magnetic field. The cradle supports and aligns the medical device in a predetermined orientation. Medical device placed in the cradle exposes a magnetic sensitive switch to the magnetic field of the magnet that produces a change in state of the magnetic sensitive switch. Medical device further includes a switch, indicator, logic circuitry, delay circuit, and detect circuit for coupling a power source to electronic circuitry. In a first mode of operation the medical device can be turned on and then turned off. In a second mode of operation the medical device cannot be turned off after being turned on.
