76 Electromagnetic Interference and GroundingElectromagnetic Interference and GroundingThe programmer is protected from disturbances resultingfrom electromagnetic interference, electrostatic dischargesand other sources, including interference from cables.However, strong electromagnetic interferences that occurin the close vicinity of electrical motors, power cables, PCs,monitors, or other electrical devices may compromise thefunction of the programmer in certain cases.Correct operation of the device can be restored withthe following:• Turn off other electronic devices.• Remove any known source of electromagnetic interference.• Turn the programmer ON and OFF or break the electricalconnection between the programmer and the source of theinterference as much as possible without causing danger.The telemetry between the programming head and theimplanted device can be impaired by electromagneticinterference (EMI). This can be observed when it becomesdifficult or even impossible to interrogate or program theimplanted device. Using the EMI test, the source of theelectromagnetic interference can be located.Renamic PSAIn the case of disruptions resulting from electromagneticinterference (EMI) that exceed the limit, the PSA moduleswitches to asynchronous pacing. The sensing amplifier isswitched off for the duration of the disruption in the channelin which the disruption is detected. Pacing continues if it isswitched on in this channel. These disruptions are visible inthe IEGM channel, but no markers are displayed.
