Cautions on Service
1) Do not hold the upper frame of the magazine insertion port in the CD mechanism module, marked by an arrow in
Fig. 21, when servicing. It's because this section is easily deformed.

2) The stage mechanism section projects below the chassis when positioned at the tenth stage or lower. So, do not
leave the stage mechanism section at these positions to avoid damage or malfunction.
3) Before removing the flexible card and pickup flexible PCB from the connectors on the relay PCB, be sure to insert a
short pin into the pickup unit first.
4) When replacing the tray motor assy, mount the 2-stage gear(Not resable) on the shaft of a new tray motor assy. (As
the gear uses snap-on fittings, push it in until it is snapped completely.)
5) When replacing the magazine holder assy, mount the worm wheel(Not resable) on the shaft of a new elevation
worm wheel.
(As the gear uses snap-on fittings, push it in until it is snapped completely.)
