1. SERVICE PRECAUTIONS
1.1 SERVICE PRECAUTIONS
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.
6. During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector
is plugged or unplugged.
7. Notes on the temperature protection
The temperature protection is set considering the use temperature range of eNAND.
If the temperature reaches the detection temperature shown below, the operation stops (ASENS is disabled).
Detection temperature on low temperature side: -25°C, return temperature: -20°C
Detection temperature on high temperature side: 86.5°C, return temperature: 80°C
8. Control of FAN
There is the control of STOP, low rotation and high rotation.
The temperature (eNAND, DVD mechanism) are detected and controlled it.
9. Pay attention to the wiring of BT cable. (It affects the sensitivity of BT antenna)

11. The part listed below is difficult to replace as a discrete component part.
When the part listed in the table is defective, replace whole Assy.
12. Attach the Detach Grill Assy (Front Panel) to the product to turn on the unit.
10. Some parts which are different from the Circuit symbol are mounted on the AV unit and CC Monitor unit.
