?Our secondary quickly fogs up even a fresh 9VDC battery installed.?
When the dew heater sensor is warmed between two fingers, the red LED lights to show power is applied and the secondary try's to clear up.?
Does anybody know how to calibrate the secondary dew heater on the 18 inch classic.? We have disassembled the secondary to get to the Dew heater, and see there is a potentiator on the circuit board.? So I believe? calibration should be possible.? Is there a
procedure to do this?
