                                    SUBJECT
    
                      A misoperation on JP-6 arpeggio function
    
       This information is for solutions to above subject, and we wish you to apply
       following procedure to above models when you have a chance to repair a failure as shown
       below :
    
   
    The Phenomenon:
    
          When connecting "TRIGGER" of Rhythm units CR-5000/8000 and TR-808 to
       "ARPEGGIO CLOCK INPUT" on JP-6, a failure occure in such a state that some steps are
       sometimes missing, especially in the range from middle to high tempo.

    
 
      JP-6/TR-808 Connection(Solution) :
    
         STEP-1 : Cut the printed foil pattern where it is located between JACK-7 (Arpeggio Clock
                  Input) and the end of C-17 0-001 Capacitor on "JACK-BOARD" 149H186C to add
                  a resistor.
    
         STEP-2 : Add the resistor 10K newly to the place between JACK-7 and the end of C-17
                  Capacitor.
    
         STEP-3 : Replace the C-17 Capacitor with new one 0.1 type.
    
               NOTE : In case of this JP-6/TR-808 connecting you do not need to take any
                      modification to TR-808 except JP-6.
    
               NOTE : This alteration has already been carried out on JP-6 from the serial number
                      322700, Please refer to the attached drawing.
    


       JP-6/CR-5000 and 8000 Connection (Solution)
    
         In case of these connections in addition to above JP-6 modification, it is necessary to take a
         modification to CR-5000/8000 :
    
         Replace C-48 0.0022 Capacitor which is mounted by the JK-6 (Jack socket) on CPU-
         BOARD in CR-5000/8000 with new one 0.056 type.
    
                NOTE : This modification has been added to CR-5000/8000 already
                       from the following serial numbers :
    
                        CR-5000 : from S/NO. 347250
                        CR-8000 : from S/NO. 349850
