Since the pickup semiconductor laser can easily damaged by
the static electricity, handle the mechanism unit with care.
To prevent damage by the static electricity during
transportation, the LD terminals are short-circuited at 2 points
on the PWB. Unsolder them by a soldering iron after
completing the connection. When you return the mechanism
unit, solder the terminals again.

Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.

•
Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means pico-farad and the unit of the capacitor
without such a symbol is microfarad. As to electrolytic
capacitor, the expression “capacitance/withstand voltage”
is used.
