An improved, long range, telemetry system for uplink and downlink telemetry transmission between an implantable medical device (IMD) and an external medical device (EMD), e.g. a programmer or monitor, specifically operable in accordance with a method for ensuring that the telemetry link is between an intended, rather than an un-intended, implantable medical device and the external medical device. Verification is effective if the operator of the EMD observes an implant event signal that is transmitted by uplink telemetry to the EMD from the IMD contemporaneously with a response-provoking action performed in the vicinity of the implant site of the intended patient. The operator directly observes the response-provoking event, when the patient is in sight, or assists the patient in timing the response-provoking event when the patient is not in sight but is at least in voice communication.
