R7000.14
Bulletin #: 35187-001
Subject: Audio becomes distorted (clipped) when the radio
is warm. The period of time required for this
problem to become evident varies depending on the
ambient temperature. This problem may not be evi-
dent at low audio levels.
Procedure
Write to ICOM's customer service department for a copy of
this service bulletin.
Bulletin #: 35887-003
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.
Procedure
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 ob-
tained 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.
