Disclosed is a remote controller for an implantable medical device having stored contraindication information, which includes information which a patient or clinician might wish to review when assessing the compatibility of a given therapeutic or diagnostic technique or activity with the patient’s implant. The resin coating material with magnetic powder has a glass transition temperature Tg of about \u221220\xb0 C. One of said half H-bridges provides a common output Vcommon and the remaining H-bridges provide drive voltages V1\u2013V4 for the segments of the display. Dynamic tuning ability is provided through the isolation amplifiers and the sample frequency of the analog-to-digital converter.
