Model: IC-R7000 Bulletin: B1904 Subject: The remote relay sometimes stays energized after a signal is no longer present. The radio must be turned off and back on to clear this situation before the modification. 1. Remove the covers from the radio and remove the main circuit board on the side of the radio. 2. Cut the trace between the base of Q5 and R106 on the foil side of the main board. 3. Install a RD6A diode (this part is critical and must be obtained from ICOM) with its cathode toward R106 across the cut in the trace. 4. Reinstall the board and insure mechanical clearance of the new diode. 5. Verify proper operation of the recorder function.
