1. A method, comprising:
detecting presence of charging signals at a coil assembly of an external component of an implantable medical device system, wherein the coil assembly comprises first and second coil segments;
in response to detection of the charging signals at the coil assembly, actuating at least one coil switch to place the coil assembly in a first electrically connected arrangement;
receiving, via the coil assembly in the first electrically connected arrangement, charging signals sent by an inductive charger at a first frequency;
detecting that the charging signals are not present at the coil assembly;
in response to detection of the absence of the charging signals, actuating the at least one coil switch to place the coil assembly in a second electrically connected arrangement; and
sending, via the coil assembly in the second electrically connected arrangement, transcutaneous signals from the external component to an implantable component at a second frequency,
wherein the second electrically connected arrangement is different from the first electrically connected arrangement and wherein the second frequency is different from the first frequency.
