IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)BEFORE RETURNING THE AUDIO PRODUCT(Fire & Shock Hazard)Before returning the audio product to the user, perform thefollowing safety checks.1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chassisand other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,cabinet, terminal board, adjustment and compartment coversor shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakagecurrent in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.* Using two clip leads, connect a 1.5k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all exposedmetal cabinet parts and a known earth ground, such asconduit or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,sensitivity to measure the AC voltage drop across theresistor (See diagram).
* Connect the resistor connection to all exposed metal partshaving a return path to the chassis (antenna, metal cabinet,screw heads, knobs and control shafts, escutcheon, etc.)and measure the AC voltage drop across the resistor.
All check must be repeated with the AC line cord plug connectionreversed.Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp.AC.) or more is excessive and indicates a potential shockhazard which must be corrected before returning the audioproduct to the owner.

If it continuous to turn, press the stop button.
1.
2.
3.
The CD lens cleaner should be effective for 30-50 operations, however if the brushes become worn out earlier then please the cleaner disc.If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft cloth.Do not drink the cleaner fluid or allow it to come in contact with the eyes. In the event of this happening then drink and / or rinse with clean water and seek medical advice.The CD cleaner disk must not be used on car CD players or on computer CD-ROM drives.All rights reserved.Unauthorized duplicating, broadcasting and renting this product is prohibited by law.
Parts code1. CD optical pickup Lens cleaner disc UDSKA0004AFZZ
TROUBLE SHOOTINGWhen the CD does not functionWhen the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. Cleanthe objective lens, and check the playback operation. When this section does not operate even after the above step is taken, checkthe following items.Remove the cabinet and follow the trouble shooting instructions."Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickuplens. Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below."
Turn the power off.Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.Do not touch the lens with the bare hand.
When a CD cannot be played1. "E-CD01" is displayed.
(1) Check the power to IC1 (LC78645E), the presence of the clock signal (33.8688 MHz) and the status of the RESET terminal (pin 66 on IC1).(2) Does the pickup move to the PICKUP-IN Switch (SW4) position?
If (1) and (2) are OK, check the system microcomputer (especially the communication line with the DSP).
2. Pressing the CD operation key is accepted, but playback does not occur.(1) Focus-HF system check(2) Tracking system check(3) Spin system check(4) PLL system check(5) Others

If the level is not normal.
1. Is focus servo activated ? (Waveform drawing Figure 40-2) Pins 7~12, 79 and 80 on IC1Check the laser diode driver Q1 peripheral circuit.
When a disc is loaded, start playback operation.
2. Does DRF change from "L" to "H" ? Is the disc rotating ?
3. Is the HF waveform normal ? (Waveform drawingFigure 40-3)
Check the spin system.
If the disc is spinning and a HF waveform is generated,DRF will go H.

Is pin 52 (C2F) on IC1 "L" ?
Yes
No
The HF waveform is normal and the time is displayednormally, but no sound is produced. Or the soundhas dropouts.
(5) Others
There are too many error flags on a damaged disc whichmakes error correction impossible.
Check again using a known good disc.
1. When playing at normal speedCheck the peripheral circuit at pin 39 (DOUT) on IC1 andthe waveform (Figure 42-2).
If OK, Check the unit.
When a disc is loaded, start play operation.
(4) PLL system check
The HF waveform is normal, but the TOC data cannot beread.
Check the PDO waveform. (Figure 42-1)
Check around pins 73~78 on IC1.Figure 42-1
