SECTION 1 PRECAUTION
1.1 Safety Precautions
!
Burrs formed during molding may be left over on some parts of the chassis. Therefore, pay attention to such burrs in the case of preforming repair of this system.
!
Please use enough caution not to see the beam directly or touch it in case of an adjustment or operation check.
(No.MA036)1-3
1.2
Preventing static electricity
Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs. 1.2.1 Grounding to prevent damage by static electricity Static electricity in the work area can destroy the optical pickup (laser diode) in devices such as CD players. Be careful to use proper grounding in the area where repairs are being performed. (1) Ground the workbench Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the traverse unit (optical pickup) on it. (2) Ground yourself Use an anti-static wrist strap to release any static electricity built up in your body.
(caption) Anti-static wrist strap
1M
Conductive material (conductive sheet) or iron plate
(3) Handling the optical pickup · In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical pickup are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.) · Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily destroy the laser diode. 1.3 Handling the traverse unit (optical pickup) (1) Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit. (2) Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a time when attaching it to the connector. (3) Handle the flexible cable carefully as it may break when subjected to strong force. (4) It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it. 1.4 Attention when traverse unit is decomposed *Please refer to "Disassembly method" in the text for the CD pickup unit. · Apply solder to the short land before the flexible wire is disconnected from the connector on the CD pickup unit. (If the flexible wire is disconnected without applying solder, the CDpickup may be destroyed by static electricity.) · In the assembly, be sure to remove solder from the short land after connecting the flexible wire.

Maintenance of laser pickup
5.7
Replacement of laser pickup
(1) Cleaning the pick up lens Before you replace the pick up, please try to clean the lens with a alcohol soaked cotton swab. (2) Life of the laser diode When the life of the laser diode has expired, the following symptoms will appear. · The level of RF output (EFM output: amplitude of eye pattern) will be low.
Turn off the power switch and,disconnect the power cord from the ac outlet.
Replace the pickup with a normal one.(Refer to "Pickup Removal" on the previous page)
Is RF output 1.0 0.35Vp-p?
NO Replace it.
YES O.K
(3) Semi-fixed resistor on the APC PC board The semi-fixed resistor on the APC printed circuit board which is attached to the pickup is used to adjust the laser power.Since this adjustment should be performed to match the characteristics of the whole optical block, do not touch the semi-fixed resistor. If the laser power is lower than the specified value, the laser diode is almost worn out, and the laser pickup should be replaced. If the semi-fixed resistor is adjusted while the pickup is functioning normally, the laser pickup may be damaged due to excessive current.
Plug the power cord in,and turn the power on. At this time,check that the laser emits for about 3seconds and the objective lens moves up and down. Note: Do not observe the laser beam directly.
Play a disc.
Check the eye-pattern at TP1.

MP3 INTRODUCTION
MP3 is an abbreviation of Motion Picture Experts Group (or MPEG) Audio Layer 3. MP3 is simply a file format with a data compression ratio of 1:10 (128 Kbps*). * Bit rate is the average number of bits that one second of audio data will consume. The unit used is Kbps. To get a better audio quality, choose a higher bit rate. The most popular bit rate for encoding is 128 Kbps. · For details information about the MP3 discs, refer to "A Guide to MP3/WMA" (separate volume).
MP3 "files (tracks)" can be recorded in "folders" --in PC terminology. During recording, the files and folders can be arranged in a way similar to arranging files and folders of computer data. "Root" is similar to the root of a tree. Every file and folder can be linked to and be accessed from the root. The illustration below shows an example of how MP3 files are recorded on a CD-R or CD-RW, how they are played back, and how they are searched for on this unit.
Compatible with ID3 Tag
Extra information data such as album title, performer name, song title, recording year, music genre and a brief comment can be stored within an MP3 file. This unit can show both ID3v1 (Version 1) and ID3v2 (version 2) tags on the display. (See page 19.) · Some characters cannot be shown correctly. · If both ID3v1 and ID3v2 are recorded on a disc, ID3v2 information will be shown.
Notes: · This unit can read a CD-ROM containing MP3 files. However, if non-MP3 files are recorded together with MP3 files, this unit will take a longer time to scan the disc. It may also cause the unit to malfunction. · This unit cannot read or play an MP3 file without the extension code <.mp3>. · This unit is not compatible with MP3 file encoded with Layer 1 and Layer 2 formats. · This unit is not compatible with Playlist**.
** A playlist is a simple text file, used on a PC, which enables users to make their own playback order without physically rearranging the files.
