    Why would you want to change a safety feature?

    The radio is good to a 3:1 SWR,  and is terminally protected at 90C.  At which it will cut back to 25% of power level,   but if the SWR is less than 3:1 ,  you might never see 90C in the Information window if your fan is working correctly .  The PA devices are good to 150C  .
