1. A method implemented in an external power transmitter of an implanted medical device system, the method comprising:
detecting satisfaction of at least one condition from a plurality of conditions of the external power transmitter, wherein the plurality of conditions includes a last handling condition that is satisfied when a time of a last handling of the external power transmitter exceeds a last handling threshold;
selecting among rates of transmission of search pulses based on the satisfaction of the at least one condition, wherein selecting comprises changing a rate of transmission of the search pulses from a first rate to a second rate; and
initiating power transmission in response to receipt of the search pulses by an internal controller of the implanted medical device system.
