bad connection from J14 to AN-
368/AD-603 (Tablet Card) or a 
bad calibration.  

Verify the foot control cable. 

Consult a XO technician. 

Nothing happens when the 

pedal is activated. 

Out of calibration 

Calibrate the control pedal 
according to the instructions in 
YB-795. 

Pedal control PCB is defective. 

Replace complete foot control: 
XO 4-1:     AO-058 
XO 4-2:     AN-200 
XO 4-6:     AN-200 
XO FLEX:  AP-703 
NB: It is not possible to change 
the PCB AN-373 or other spare 
part on the pedal. Any defective 
pedal must be returned for repair 
and calibration.
