CHASSIS
Once the output is set, adjust the sensitivity by driving
forward at approximately 25 mph and press the brake
pedal. The vehicle and trailer should make a smooth
stop. If the stop seems slow and more aggressive
braking is desired, adjust the sensitivity level by rotating
the LED display knob clockwise. If the stop seems too
aggressive, adjust the sensitivity level by rotating the
knob counter-clockwise.
Make several stops at various speeds and adjust
the sensitivity until stops are smooth and firm. Slight
adjustment to the output control may also be desirable.
For more information, refer to the Curt Spectrum Brake
Controller Manual in Newgle.
