- Page 8 Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All wire- less microphones have low-power transmitters (less than 0.05 watts output) which are unlikely to cause difficulty, especially if they are at least a few inches away. However, since a “body-pack” mic transmitter typically is placed against the body, we suggest attaching it at the belt, rather than in a shirt pocket where it may be immediately adjacent to the medical device.
