- 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 adjusting, 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.
