_____________________________________________________________
 
 
Model:
 
DCM-280, 
DCM-380       
 
 
Subject: 
Change in MICON
 
 
 
 
 
 
 
 
 
 
Symptom:
  1) The unit regards a CD-DA Disc that has a very low reflection 
ratio as a CD-RW Disc. As a result, the servo-gain increases four times, and 
sometimes, the unit is incapable of playing the disc.  
2) The unit is incapable of reading only the TOC on the 80th Track. 
 
 
Solution:  
We changed the MICON (IC502) from a CXP82052-140Q 
Ver3.00
 
to CXP82052-146Q 
Ver2.04
.  Therefore, please apply the modification when the 
symptoms occur.
 
 
• How to confirm the Version of the MICON: 
1) While holding "OPEN/CLOSE" and "REPEAT" buttons down simultaneously, 
press Power Switch button. The FL Tube Display indicates all modes.  
2) The Version appears on the Display when the "DISC SKIP" button is pressed.
