Cautionary Notes

Before beginning the procedure, please read
through this document. The matters described may
differ according to the model.
Back Up User Data!

Save and Load" in the Service Notes and save the data. After completing the
procedure, restore the backed-up data to the product.
Part Replacement
When replacing components near the power-supply circuit or a heat-
generating circuit (such as a circuit provided with a heat sink or including a
cement resistor), carry out the procedure according to the instructions with
respect to the part number, direction, and attachment position (mounting so as
to leave an air gap between the component and the circuit board, etc.).
Parts List
A component whose part code is ******** cannot be supplied as a service part
because one of the following reasons applies.
• Because it is supplied as an assembled part (under a different part code).
• Because a number of circuit boards are grouped together and supplied as
a single circuit board (under a different part code).
• Because supply is prohibited due to copyright restrictions.
• Because reissuance is restricted.
• Because the part is made to order (at current market price).
Circuit Diagram
In the circuit diagram, "NIU" is an abbreviation for "NOT IN USE." The circuit
board and circuit-board diagram show silkscreened indications, but no
components are mounted.
