2. Navigate to RX CONFIG, and select the corresponding mode for the device (Wired, Knob, or Rocker).


The Teradek RT App for iOS devices allows users to configure all of the major functions via Bluetooth such as motor axis selection, creating lens maps, start/stop, and includes virtual sliders for calibrating FIZ controls on the MDR.S.
