A selected routine to be generated in response to a command signal from the external command unit is stored. A first access signal is transmitted from the command unit to the implant, to enable a computer within the implant to receive a command signal. A command signal is transmitted, from the command unit, to operate the selected routine. The operation of the selected routine is inhibited unless both the first access signal and the command signal have been generated. | |
