Notes on Chip Component Replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be damaged by heat.
Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270˚C during
repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering
or unsoldering.

ELECTRICAL PARTS LIST
NOTE:
• Due to standardization, replacements in
the parts list may be different from the

components used on the set.
• -XX and -X mean standardized parts, so
they may have some difference from the
original one.
• RESISTORS
All resistors are in ohms.
METAL:Metal-film resistor.
METAL OXIDE: Metal oxide-film resistor.
F:nonflammable
Ref. No.
• Items marked “*” are not stocked since
they are seldom required for routine service.
Some delay should be anticipated
when ordering these items.
• SEMICONDUCTORS
In each case, u : µ, for example:
uA.. : µA.. uPA.. : µPA..
uPB.. : µPB.. uPC.. : µPC.. uPD.. : µPD..
