Safety Precautions

1. This design of this product contains special hardware and many circuits and components specially for safety purposes. For continued protection, no changes should be made to the original design unless authorized in writing by the manufacturer. Replacement parts must be identical to those used in the original circuits. Services should be performed by qualified personnel only.

2. Alterations of the design or circuitry of the product should not be made. Any design alterations of the product should not be made. Any design alterations or additions will void the manufacturer`s warranty and will further relieve the manufacture of responsibility for personal injury or property damage resulting therefrom.

3. Many electrical and mechanical parts in the products have special safety-related characteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in the Parts List of Service Manual. Electrical components having such features are identified by shading on the schematics and by ( ) on the Parts List in the Service Manual. The use of a substitute replacement which does not have the same safety characteristics as the recommended replacement parts shown in the Parts List of Service Manual may create shock, fire, or other hazards.

4. The leads in the products are routed and dressed with ties, clamps, tubings, barriers and the like to be separated from live parts, high temperature parts, moving parts and/or sharp edges for the prevention of electric shock and fire hazard. When service is required, the original lead routing and dress should be observed, and it should be confirmed that they have been returned to normal, after re-assembling.

5. Leakage currnet check (Electrical shock hazard testing)After re-assembling the product, always perform an isolation check on the exposed metal parts of the product (antenna terminals, knobs, metal cabinet, screw heads, headphone jack, control shafts, etc.) to be sure the product is safe to operate without danger of electrical shock.Do not use a line isolation transformer during this check.

Plug the AC line cord directly into the AC outlet. Using a "Leakage Current Tester", measure the leakage current from each exposed metal parts of the cabinet , particularly any exposed metal part having a return path to the chassis, to a known good earth ground. Any leakage current must not exceed 0.5mA AC (r.m.s.)Alternate check methodPlug the AC line cord directly into the AC outlet. Use an AC voltmeter having, 1,000 ohms per volt or more sensitivity in the following manner. Connect a 1,500 10W resistor paralleled by a 0.15 F AC-type capacitor between an exposed metal part and a known good earth ground.Measure the AC voltage across the resistor with the AC voltmeter. Move the resistor connection to eachexposed metal part, particularly any exposed metal part having a return path to the chassis, and meausre the AC voltage across the resistor. Now, reverse the plug in the AC outlet and repeat each measurement. voltage measured Any must not exceed 0.75 V AC (r.m.s.). This corresponds to 0.5 mA AC (r.m.s.).

Warning1. This equipment has been designed and manufactured to meet international safety standards.2. It is the legal responsibility of the repairer to ensure that these safety standards are maintained.3. Repairs must be made in accordance with the relevant safety standards.4. It is essential that safety critical components are replaced by approved parts.5. If mains voltage selector is provided, check setting for local voltage.

Preventing static electricity1. Grounding to prevent damage by 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.

2. About the earth processing for the destruction prevention by static electricity In the equipment which uses optical pick-up (laser diode), optical pick-up is destroyed by the static electricity of the work environment.Be careful to use proper grounding in the area where repairs are being performed.

2-1 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.

2-2 Ground yourself Use an anti-static wrist strap to release any static electricity built up in your body.

3. Handling the optical pickup1. 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.)

2. 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.

4. 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

Conductive material (conductive sheet) or iron plate

(caption)Anti-static wrist strap

Attention when traverse unit is decomposed

1. Remove the disk stopper and T. bracket on the CD changer mechanism assembly. 2. Disconnect the harness from connector on the CD motor board.3. CD traverse unit is put up as shown in Fig.1. 4. Solder is put up before the card wire is removed from connector CN601 on the CD servo control board as shown in Fig. 2. (When the wire is removed without putting up solder, the CD pick-up assembly might destroy.) 5. Please remove solder after connecting the card wire with CN601 when you install picking up in the substrate.

*Please refer to "Disassembly method" in the text for pick-up and how to detach the CD traverse mechanism.

Precautions for measurement1. Apply 30pF and 33kohm to the IF sweeper output side and 0.082 F and 100kohm in series to the sweeper input side.2. The IF sweeper output level should be made as low as possible within the adjustable range.3. Since the IF sweeper is a fixed device, there is no need to adjust this sweeper.4. Since a ceramic oscillator is used, there is no need to perform any MPX adjustment.5. Since a fixed coil is used, there is no need to adjust the FM tracking.6. The input and output earth systems are separated. In case of simultaneously measuring the voltage in both of the input and output systems with an electronic voltmeter for two channels, therefore, the earth should be connected particularly.7. In the case of BTL connection amplifier, the minus terminal of speaker is not for earthing. Therefore, be sure not to connect any other earth terminal to this terminal. This system is of an OTL system.

Maintenance 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. 1. The level of RF output (EFM output:ampli tude of eye pattern) will below.

Is the level ofRFOUT under

1.25V 0.22Vp-p?Replace it.

NO

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.

Hardware reset. An external device asserts RESET (active LOW)

to execute a decoder hardware reset. To ensure proper initializat-

ion after power is stable, assert RESET for at least 20 s.

System clock. Decoder requires an external 27 MHz TTL oscillator.

Drive with the same 27-MHz as VCK.

Host chip select. Host asserts CS to select the decoder for a read

or write operation. The falling edge of this signal triggers the read or

write operation.

Host address bus. 3-bit address bus selects one of eight host interf-

ace registers.

8-bit bi-directional host data bus. Host writes data to the decoder

Code FIFO via HDATA[7:0]. MSB of the 32-bit word is written

first. The host also reads and writes the decoder internal registers

and local SDRAM/ROM via HDAT[7:0].

Host interrupt. Open drain signal, must be pulled-up to 3.3 volts.

Driven high for 10 ns before tristate.

Read strobe in I mode. Must be held HIGH in M Mode.

Read/write strobe in M mode. Write strobe in I mode. Host asserts

R/W LOW to select write and LOW to select Read.

Active LOW to indicate host initiated transfer is not complete.

WAIT is asserted after the falling edge of CS and reasserted when

decoder is ready to complete transfer cycle. Open drain signal, mu-

st be pulled-up to 3.3 volts. Driven high for 10 ns before tristate.

Horizontal sync. The decoder begins outputting pixel data for a new

horizontal line after the falling (active) edge of HSYNC.

Video clock. Clocks out data on input. VDATA[7:0]. Clock is ty-

pically 27 MHz.

Video data bus. Byte serial CbYCrY data synchronous with VCLK.

At power-up, the decoder does not drive VDATA. During boot-up,

the decoder uses configuration parameters to drive or 3-state

VDATA.

Vertical sync. Bi-directional, the decoder outputs the top border of

a new field on the first HSYNC after the falling edge of VSYNC.

VSYNC can accept vertical synchronization or top/bottom field no-

tification from an external source. (VSYNC HIGH = bottom field.

VSYNC LOW = Top field)
