Caution on Disassembly
Follow the below-mentioned notes when disassembling
the unit and reassembling it, to keep it safe and ensure
excellent performance:
1. Take cassette tape and compact disc out of the unit.
2. Be sure to remove the power supply plug from the wall

outlet before starting to disassemble the unit.

3. Take off nylon bands or wire holders where they need to

be removed when disassembling the unit. After servicing
the unit, be sure to rearrange the leads where they were
before disassembling.

4. Take sufficient care on static electricity of integrated

circuits and other circuits when servicing.

Note 1: How to open the changer manually. (Fig. 7-3)
1.  In this state, turn fully the lock lever in the arrow direction through

the hole on the loading chassis bottom.

2. While holding the lock lever, rotate the cam gear anticlockwise until the

cam gear rib engages with the clamp lever. (Fig. 8-1)

3.  After that, push forward the CD slide holder.

Note 2:
1. After removing the connector for the optical pickup from the

connector, wrap the conductive aluminium foil around the front end
of the connector so as to protect the optical pickup from electro-
static damage.

Note 3:
1. Be careful not to break the claw of the CD mechanism.
2. When fining back the cam gear assembly, let it lock by front

movement.
