Caution on Disassembly
The disassembling the machine or assembling it after
repair, observe the following instructions to ensure safety
and keep its performance.
1. Unload the compact disc, and mini-disc, cassette tape
from machine.
2. Be sure to unplug the power cable before starting
disassembly of the machine.
3. When disassembling each section, remove the nylon
band or wire arrangement.
After servicing the unit, be sure to rearrange the leads
where they were before disassembling.
If a screw of improper length is fit to the MD mechanism.
(A screw fit the part to the mechanism chassis of MD
section), it may contact the optical pickup, impeding
normal operation. Hence, due care must be taken.
4. While repairing, pay utmost attention to static electricity
on ICs.

Notes for servicing (For MD-MX30 only)
• This model is equipped with a fan. If you remove the fan to
service the unit, it enters the protection mode and the
power cannot be turned on by pressing the POWER
button. In such a case, follow the procedure below.
(Refer to Fig.10-1.)
1. Check whether a resistor (RV 66,39ohm,1/2W) is inserted.If
not, connect it (39ohm,1/2W).
2. Connect the patterns circled with a dotted line by soldering.
• Desolder to reassemble the unit after repairing. If you fail
to desolder, the power turns off soon because the unit
enters the protection mode when the fan rotates at a high
speed (high power).
• These steps are unnecessary to service the unit with the
fan connected.
