1. SERVICE PRECAUTIONS

1.1 SERVICE PRECAUTIONS
A
1. You should conform to the regulations governing the product (safety, radio and noise, and other regulations),
and should keep the safety during servicing by following the safety instructions described in this manual.
2. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic
induction.
3. Before disassembling the unit, be sure to turn off the power. Unplugging and plugging the connectors during
power-on mode may damage the ICs inside the unit.
4. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment
(shorting-solder) by referring to "the DISASSEMBLY" .
5. After replacing the pickup unit, be sure to skew adjustment.
B
6. When a flash ROM needs to be replaced by service, do not replace an IC but a core unit (as no encryption key is
written in a flash alone).
7. During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector
is plugged or unplugged.
8. About region codes
With the RC models, the region code may have been changed for some sale destinations.
In that case, a region display area of the name plate on the main unit has been overwritten (with a sticker).
If the region code is reset to its initial value due to replacement of the DVD unit etc., change the region code to
that written on the name plate of the main unit.
Contact the PSN Division for the region changing procedure.
9. Countermeasures to user complaints on iPhone/iPod touch lip synchronization
When a video is replayed, the video and audio may be out of synchronization depending on the connected
