About the PNLB and CNCT Assys
The P

About the Flash ROM (IC3) in the MAIN Assy
Replacement of the Flash ROM (IC3: DYW1
8
14) in the MAI
N
Assy is not possible during service, because writing of
the MAC address on the production line is required.
Therefore, the Flash ROM (IC3) is not supplied as a service part. If the Flash ROM is defective, replace the whole MAI
N
Assy.
About work re
q
uired after replacement of the Traverse Mechanism Assy (09SD)
After replacement of the traverse mechanism Assy (09SD), reset the LD lighting time to zero.
How to Reset: See "
7
Drive LD life reset" in "[3] Indication of various information" in "6.1 SER
V
ICE MODE."
About transfer of the accumulated LD lighting time data after replacement of the MAIN Assy
This unit is equipped with self-diagnostic functions for the drives in Service mode. The service-life check for the laser
diode (for CDs/D
V
Ds) among the self-diagnostic functions uses the accumulated lighting time for judgment. If it is
7,000 hours or less, the laser diode is judged as OK. The accumulated lighting time of the LD is stored in the Flash ROM
(IC3: DYW1
8
14) in the MAI
N
Assy. Therefore, after replacement of the MAI
N
Assy, the accumulated lighting time of the
LD is cleared and proper judgment will not be possible after that. To avoid such a situation, when replacement of the
MAI
N
Assy is required, transfer the LD accumulated lighting time data.
Before replacement, confirm the drive LD lighting time in Service mode and take note of the time value. After replacement
is finished, enter Service mode then change the drive LD lighting time value to what you noted.
For details on how to confirm and change the LD lighting time, see "
8
Drive LD life manual input" in "[3] Indication of
various information" in "6.1 SER
V
ICE MODE."
About the self-diagnostic functions for the drives
This unit has self-diagnostic functions for the drives in Service mode. Use the self-diagnostic functions to check the drives if
the problem symptom pointed out by the customer is a malfunction related to the drives or if a drive-related error is logged in
the error history.
For details on the self-diagnostic functions for the drives, see "[5] Drive Self-Diagnosis" and "[6] Contents of Drive
Self-Diagnosis" in "6.1 SER
V
ICE MODE."
