A monitor for a therapeutic device such as a cochlear implant monitors the leakage RF signals between the external and the internal components. In one embodiment, absence of RF signals is interpreted by the monitor as being indicative of either an out-of-range condition or a flat battery condition and a sound and/or visual signal is generated to indicate this condition to an attendant. In a more complex embodiment, special indication signals either are superimposed on the standard signals and used to uniquely identify the cochlear implant or to provide an indication of certain preselected features of the external component. The monitor is especially useful for infant cochlear implants.
