How to calibrate the Headrush Mx5 expression pedal

To calibrate the MX5's built in expression pedal, hold down the encoder (knob that says "push to enter" under it) and footswitch 2 simultaneously while powering on the unit. Once powered on, footswitch 1 will be flashing green. Wait until the screen says "loading". Now you are in calibration mode. First, position the expression pedal with the toe in the up position then press footswitch 1. Wait until footswitch 2 starts flashing green then position the expression pedal with the toe in the down position and press footswitch 2. Now for the final part, when footswitch 3 is flashing green position the expression pedal as close to half way as possible the press footswitch 3. After that it should be calibrated!
