- CD Player Service Precautions
1. For PU unit(CGY1036) handling,please refer to
"Disassembly"(Fig.20).
During replacement,handling precautions shall be
taken to prevent an electrostatic discharge(protection
by a short pin).
2. Be sure to turn the power off before disassembly. An
internal IC might be destroyed when a connector is
plugged or unplugged.
3. These CD players have been designed to be set
upright in a car. Therefore, when operating or adjust-
ing, set them upright.
- CDX-M8086ZT/E, CDX-M8086ZT-91/E, CDX-M8186ZT/WL, and CDX-M8186ZT-91/WL have adopted AVC-
LAN.
- The CD mechanism employed in this model is one of C3TV series.
- See the separate manual CX-624 (CRT1631) for the CD mechanism description and disassembly.
- See the separate manual CDX-P616/UC (CRT1632) for CD circuit description.
