30 Using RenamicTelemetryThe programmer and the implanted device communicatetelemetrically via the programming head or using SafeSyncRF telemetry. Not every device supports SafeSync RFtelemetry. Consult the technical manual of the respectiveimplantable pacemaker or ICD.SafeSync RF telemetry establishes a wandless telemetryconnection between the programmer and devices withthe BIOTRONIK SafeSync function. The programmer anddevices that offer the BIOTRONIK SafeSync function have aspecific type of transmitter with which high frequency radiotransmission is possible. Wandless telemetry involves theoutput data (digital as well as analog) from the implanteddevice being converted into digitally coded pulses andtransmitted over an inductive coupling between the coils ofthe programming head and those of the implanted device.With some implanted devices, telemetry cannot be carriedout until a reed switch in the implanted device has beenclosed. For this purpose, a strong permanent magnet hasbeen integrated into the programming head. Before theprogramming head and the implanted device can exchangedata, the reed switch in the implanted device is closed.When the reed switch is open, telemetry is blocked.This protects the implanted device from unintentionalreprogramming. With some implantable devices, closing thereed switch also switches the device over to an asynchronouspacing program. See the technical manual of the respectiveimplanted device.
