The matters described may differ according to
the model.
BACK UP USER DATA!
User data may be lost during the course of the procedure.

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.
