1. Press and hold the Store button while powering up the RP355.
2. When the display prompts you with , release the Store button, which is now flashing.
3. Press and hold the flashing Store button for 3 seconds until appears in the display
and release. The Restore procedure takes several seconds to complete; during the procedure,
the display will count up. After the Restore procedure is complete, the Expression Pedal cali-
bration procedure will begin. See step two of the Expression Pedal Calibration section below.
Expression Pedal Calibration
The Expression Pedal on the RP355 needs to be recalibrated for use after a factory reset has
been performed. This calibration procedure is automatically entered after a factory reset proce-
dure. (You can also initiate the calibration procedure by pressing and holding the Up and Down
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 appears in the display (,
, and will be displayed before is accessed, after about 5 seconds.)
2. When the Display prompts you with , rock the Expression Pedal forward (toe
down) and press either the Up or Down Footswitch.
3. When the Display prompts you with , rock the Expression Pedal back (toe up) and
press either the Up or Down Footswitch.
4. The Display now prompts you to calibrate the V-Switch sensitivity (), where is
the current V-Switch threshold. Rock the Expression Pedal forward and press firmly on the
toe once to turn the V-Switch on (), and again to turn the V-Switch off ().
5. If the V-Switch is too sensitive, press the right Up Footswitch to raise the threshold (range
is -). 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 ,anerrorhasoccurredandsteps2through5
should be repeated.
