GENERAL INFORMATION
DIAGNOSIS
SERVICE MODE
Types of Service Modes
The unit is provided with three microcomputers: a microcomputer that controls key input and FL/LED display (display u com.)
a mechanism-control microcomputer that drives the disc loading mechanism and servo mechanism, and a system control
microcomputer that controls the whole system. The following test modes are provided for diagnosis of each microcomputer.
~ Mode for checking key input in the display block and for display functions
In this mode, key input and the display function associated with such input can be checked.
Ÿ Mode for checking operation of the mechanical and servo blocks (using a connected PC)
In this mode, once you have connected a PC via the CN301 connector, which is directly connected to the mechanism-control
microcomputer on the MAIN Assy through a special device, operation of the mechanical and servo blocks can be checked.
! Mode for checking audio output (using a connected PC)
In this mode, once you have connected a PC via the CN201 connector, which is directly connected to the system control
microcomputer on the MAIN Assy through a special device, audio output can be checked.
Before entering this mode, it is necessary to disconnect the CN1101 connector on the MFLB Assy and remove the upper unit
(jog and display block), because the communication line is shared between audio output and display functions.
⁄ Mode for checking the load on the Jog dial
In this mode, the load (light/heavy) on the Jog dial while it is rotated is subjectively measured.
@ Mode for checking the error log
In this mode, the latest 16 errors can be checked.
¤ Mode for checking the version of the software program
In this mode, the version of the software program for each microcomputer can be checked.
