Expression Pedal Calibration

The Expression Pedal on the RP255 needs to be recalibrated for use after a factory reset has been performed. This calibration procedure is automatically entered after a factory reset procedure. (You can also initiate the calibration procedure by pressing and holding both Footswitches for approximately 5 seconds.) In the event the Pedal’s calibration fails, or if the Pedal does not function properly, it can be re-calibrated using the Pedal Calibration procedure. This will not erase the User presets.The procedure for Calibrating the Expression Pedal is as follows:

1.Press and hold the Up/Down Footswitches until PDLCAL appears in the display (BYPASS and TUNER will be displayed before PDLCAL is accessed)

2.When the Display prompts you with TOE DN, rock the Expression Pedal forward (toe down) and press either Footswitch.

3.When the Display prompts you with TOE UP, rock the Expression Pedal back (toe up) and press either Footswitch.

4.The Display now prompts you to calibrate the V-Switch sensitivity (VSwxxx), where XXX is the current V-Switch threshold. Rock the Expression Pedal forward and press firmly on the toe

once to turn the V-Switch on (wah ON), and again to turn the V-Switch off (wahOFF).

5.If the V-Switch is too sensitive, press the right Up Footswitch to raise the threshold (range is

0-200). Keep testing the V-Switch sensitivity and adjust the threshold until it only engages when you want it to (too sensitive a setting will lead to the V-Switch falsely triggering on or off when using the Expression Pedal).

6.When the V-Switch sensitivity is set to your satisfaction, press both Up/Down Footswitches simultaneously to exit.

Note: If the Display shows error, an error has occurred and steps 2 through 5 should be repeated.
