Fix for Sony MZ-R55 Recording Self-start Problem
Hoshing Kwong ([email protected])
Problem: Sony MZ-R55 units have been known to go into record mode while at idle and
over-write unprotected MD.
Cause: The signal pin attached to the record switch is at a
"floating" state and sensitive to battery voltage level.
Solution: Verify that the record switch is functioning
properly (not sticky). Solder a small "surface mount type" capacitor
(100 nf) between the signal pin of the record switch and ground.
Refer to diagram attached for more details.
