Sometimes you will need to turn off the high SWR shut down so you can set the SWR on a new antenna.
To turn the SWR shutdown off, on the SR-655HPC / SR-955HPC, you will need to use the function menu,
Hold the function button down until the menu pulls up. Then press and release the function button repeatedly until you get to the setting labeled TSR. Rotate the CH selector, so it changes to off. Press the color button, and you will exit the function menu. The SWR shut down has been successfully turned off.
We recommend you turn this function back on after you finish tuning your antennas.
