WARNINGS
The controller has voltage present on the control cable wires, even when the power button has been pushed to “Off”. Unplug the power supply and disconnect the 25-pin D-sub connector before making any connections or cutting or splicing the cable wires. If the controller has power and the control cable wires short out, this will damage the driver chips inside the controller. We HIGHLY recommend that you ground the chassis of the controller to your station ground. When operating with over 200 watts, it is important that you do not transmit while the antenna is adjusting.
