Rough Transmitter Tuning is one of the Eyes Augmentations in Deus Ex: Mankind Divided.
Description[]
Due to the sensitivity to the ambient electromagnetic field produced by the user's other installed augmentations, the Smart Vision frequency transmitters require a dedicated power supply to counteract a negative signal-to-noise ratio. With fine-tuning, the frequency modulator can be set to cancel-out the noise from the user's EM field, requiring less energy.
