Damaged power cords may lead to fire accidents, so please be sure that there are no damages. If you find a damaged power cord, please exchange it with a suitable one.

9 There should be no spark traces or similar marks on the power plug.

When spark traces or similar marks are found on the power supply plug, please check the connection and advise on secure connections and suitable usage. Please exchange the power cord if necessary.

a Safe environment should be secured during servicing.

When you perform repairs, please pay attention to static electricity, furniture, household articles, etc. in order to prevent injuries. Please pay attention to your surroundings and repair safely.

2. Adjustments

To keep the original performance of the products, optimum adjustments and confirmation of characteristics within specification. Adjustments should be performed in accordance with the procedures/instructions described in this manual.

4. Cleaning

For parts that require cleaning, such as optical pickups, tape deck heads, lenses and mirrors used in projection monitors, proper cleaning should be performed to restore their performances.

3. Lubricants, Glues, and Replacement parts

Use grease and adhesives that are equal to the specified substance. Make sure the proper amount is applied.

5. Shipping mode and Shipping screws

To protect products from damages or failures during transit, the shipping mode should be set or the shipping screws should be installed before shipment. Please be sure to follow this method especially if it is specified in this manual.

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. 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.

3. To protect the pickup unit from electrostatic discharge during servicing, take an appropriate treatment (shorting-solder) by referring to "the DISASSEMBLY".

4. After replacing the pickup unit, be sure to check the grating.

5. Be careful in handling ICs. Some ICs such as MOS type are so fragile that they can be damaged by electrostatic induction.

6. On CD Core Unit, actual cable colors and silk print are different.

7. CD Mech. Assembly Wrong Installation Check If iPod corresponding mech. assembly is installed at iPod non corresponding model, or if iPod non corresponding mech. assembly is installed at iPod corresponding model by mistake, this becomes error indication with CDS, USB sources as shown below;

Judgment condition of wrong installation is as follows;

* The condition becomes as shown above since a microcomputer of corresponding USB mech. assembly and a microcomputer of iPod corresponding mech. assembly are the same.

However, this is determined by the presence or absence of authentication IC since problem occurs depending on different mech. assembly.

1.2 NOTES ON SOLDERING

For environmental protection, lead-free solder is used on the printed circuit boards mounted in this unit. Be sure to use lead-free solder and a soldering iron that can meet specifications for use with lead-free solders for repairs accompanied by reworking of soldering.

Compared with conventional eutectic solders, lead-free solders have higher melting points, by approximately 40 C. Therefore, for lead-free soldering, the tip temperature of a soldering iron must be set to around 373 C in general, although the temperature depends on the heat capacity of the PC board on which reworking is required and the weight of the tip of the soldering iron.

Compared with eutectic solders, lead-free solders have higher bond strengths but slower wetting times and higher melting temperatures (hard to melt/easy to harden).

The following lead-free solders are available as service parts: Parts numbers of lead-free solder: GYP1006 1.0 in dia. GYP1007 0.6 in dia. GYP1008 0.3 in dia.
