Model: MDS-501 No. 417
Subject: Track name does not appear Date: November 30, 1994
Applicable Serial no. 504,899 and lower
Symptom:
(**) When selecting the last track by quickly rotating the Jog dial, the name of the last
track does not appear and "No Name" is shown in the display.
Solution: Replace the System controller (on the display board), IC301, M38197MA-071-FP with
the improved version M38197MA-076-FP. In addition you must remove the small
board located between the Digital board and the Mechanism. Remove both the board
and its lead wires. If attached, remove the jumper wires from the Display board and
restore the PCB patterns that have been cut (See diagram). Failure to restore the
patterns will result in faulty clock and date operation. Note that on some sets there
are no patterns cut, instead two jumper wires are missing on the Display board (one
jumper is located near S321 and the other near R314). In this case attach the missing
jumper wires.
