Event Description

Additional information received from the consumer reported that even though they tried to put the antenna in exactly the same place, in the same orientation, every time, it seemed they could have all eight coupling boxes lit, or any number fewer.According to the consumer this happened whenever they placed the antenna directly on their skin when they were sitting and not moving.The consumer was asked what was done to resolve the poor coupling and stated nothing was done to resolve the poor coupling as the person they spoke with agreed it could be ¿finicky¿ and difficult to achieve coupling.No patient symptoms or further complications were anticipated.
