[ Important symbols for good services ]

In this manual, the symbols shown-below indicate that adjustments, settings or cleaning should be made securely. When you find the procedures bearing any of the symbols, be sure to fulfill them:

1. Product safety

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. Adjustments

To keep the original performances of the product, optimum adjustments or specification confirmation is indispensable. In accordance with the procedures or instructions described in this manual, adjustments should be performed.

3. Cleaning

For optical pickups, tape-deck heads, lenses and mirrors used in projection monitors, and other parts requiring cleaning, proper cleaning should be performed to restore their performances.

4. Shipping mode and shipping screws

To protect the product from damages or failures that may be caused during transit, the shipping mode should be set or the shipping screws should be installed before shipping out in accordance with this manual, if necessary.

5. Lubricants, glues, and replacement parts

Appropriately applying grease or glue can maintain the product performances. But improper lubrication or applying

glue may lead to failures or troubles in the product. By following the instructions in this manual, be sure to apply the prescribed grease or glue to proper portions by the appropriate amount.For replacement parts or tools, the prescribed ones should be used.

- Service Precautions

1.For pickup unit(CXX1305) handling, please refer to"Disassembly"(see page 109).

During replacement, handling precautions shall be taken to prevent an electrostatic discharge(protection by a short pin).

2.During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector is plugged or unplugged.

3.Please checking the grating after changing the service pickup unit(see page 93).

4.You can't recover the data if the HDD should break for some reason.

5.Be careful to handle HDDs (as HDD navigation systems).

6.An external power supply box is used along with the unit. Customers may consult their dealers without bringing the box.

7.You can't play your data with any HDD or product other than the original one, because each product has its ID (CXK2000EN) for protecting copyrights. Please use both of the ID and the data in the HDD as paired with each other. (For example, if you exchange the digital units because your unit has defects, remove IC3305: CXK2000EN from the defective unit and install it in the new unit for use.)
