Disassembly/adjustment prohibited items

A. Paint-socked screws
NOTE
• Paint-locked screws show that the assembly or unit secured can only be adjusted
or set at the factory and should not be adjusted, set, or removed in the field.
B. Red-painted screws
NOTES
• When the screws are removed, the red paint is coated on the points where read-
justment is required.
• Once a red-painted screw is removed or loosened, you should make the adjust-
ment. Accordingly, check the adjustment items in this manual and make the nec-
essary adjustments. Note that when two or more screws are used on the part in
question, only one representative screw may be marked with red paint.

tions are given in the "Adjustment/Setting" section.

PWBs" and follow the corresponding removal procedures.
• The removal procedures given in the following sections omit the removal of con-
nectors and screws securing the circuit board support or circuit board.
• Where it is absolutely necessary to touch the ICs and other electrical components
