  The modification consists of:
    1. Add 1pc 1000pF/50V chip capacitors to the DAMP PCB
    2. Change 4pcs resistors on the DAMP PCB from 0 ohm to 100 ohm
    3. Add 4 pcs 10pF/50V chip capacitor to the DAMP PCB
    4. Add GND wire between the Digital Receiver Module and the DAMP PCB
       Make sure to install the GND wire (REE1749-J) when replacing the PCB (REP4869BA)

  Step 1: Add 1pc 1000pF/50V chip capacitors to the DAMP PCB


                                                     DAMP PCB




                        Add 1000pF on C5617
