Model:

MDS-501

No.

417

Subject: Track name does not appear
Applicable Serial no. 504,899 and lower

Date: November 30, 1994

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.
