For five bucks you can barely buy a hamburger. Or for the same five bucks you can buy a service manual. Much more useful. (and better for your health, depending on where you buy your hamburgers).
Yes, there are free manual sites out there, but if they don't have what you want, you have to pay.
And five bucks isn't much. Not for full specs, schematics and adjustment and parts replacement procedures.
My only criticism is that grayscale illustrations aren't well rendered, but I've seen worse.
Schematics and text are clear.
I'll be happy to purchase from here again.

Impressively thorough. Even the simple operators manual helped me "fix" one of the 2 CD players in the unit. This unit reads CD's from the top so they should be installed in the magazines "upside down" from typical CD players. The CD player service manual helped me unjam a stuck carriage because somebody transported the box laying down loaded with CD's. A little lens cleaning & the player now works well! Thanks for you help at a great price! Joe

I was skeptical at first but later found the manual to be good quality for the price. It took a couple hours to receive the email with the download link, well worth the wait. Thanks.

very helpful, I could not have cleaned motherboard and replaced the main fan without it

Good manual, schematics nice and clear with good quality scanning. Woul dhave been nice to have immediate access after purchasing though.

For proper circuit construction, use of insulation tubes, bonding, gaps to PWB, etc, is involved. The wiring connection and routing to the PWB are specially planned using clamps to keep away from heated and high voltage parts. Ensure that they are placed back in their original positions after repair or inspection. If extended damage is caused due to negligence during repair, the legal responsibility shall be with the repairing company. Check for safety after repair. Check that the screws, parts and wires are put back securely in their original position after repair. Ensure for safety reasons there is no possibility of secondary ploblems around the repaired spots. If extended damage is caused due to negligence of repair, the legal responsibility shall be with the repairing company. Caution in removal and making wiring connection to the parts for the automobile. Disconnect the battery terminal after turning the ignition key off. If wrong wiring connections are made with the battery connected, a short circuit and/or fire may occur. If extensive damage is caused due to negligence of repair, the legal responsibility shall be with the repairing company. Cautions regarding chips. Do not reuse removed chips even when no abnormality is observed in their appearance. Always replace them with new ones. (The chip parts include resistors, capacitors, diodes, transistors, etc). The negative pole of tantalum capacitors is highly susceptible to heat, so use special care when replacing them and check the operation afterwards. Cautions in handling flexible PWB Before working with a soldering iron, make sure that the iron tip temperature is around 270 . Take care not to apply the iron tip repeatedly(more than three times)to the same patterns. Also take care not to apply the tip with force.
7. Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit. 8. Cautions in checking that the optical pickup lights up. The laser is focused on the disc reflection surface through the lens of the optical pickup. When checking that the laser optical diode lights up, keep your eyes more than 30cms away from the lens. Prolonged viewing of the laser within 30cms may damage your eyesight. 9. Cautions in handling the optical pickup The laser diode of the optical pickup can be damaged by electrostatic charge caused by your clothes and body. Make sure to avoid electrostatic charges on your clothes or body, or discharge static electricity before handling the optical pickup. 9-1. Laser diode The laser diode terminals are shorted for transportation in order to prevent electrostatic damage. After replacement, open the shorted circuit. When removing the pickup from the mechanism, short the terminals by soldering them to prevent this damage. 9-2. Actuator The actuator has a powerful magnetic circuit. If a magnetic material is put close to it. Its characteristics will change. Ensure that no foreign substances enter through the ventilation slots in the cover. 9-3. Cleaning the lens Dust on the optical lens affects performance. To clean the lens, apply a small amount of isopropyl alcohol to lens paper and wipe the lens gently.
ADJUSTMENT
Item FM noise convergence Clock accuracy Procedure 1. Input the 98.1MHz/55dBu(1kHz 30% MOD) signal. 2. Adjust the outputs to -18+3/-3dB by VR102 when the SG output is set to -20dBu. 1. Turn on the power switch, pressing the "M4" and "M2" button to make the unit the test mode. 2. Set a universal timer to TP101(T-BASE), adjust TC101 so that a reading of the meter is 0+0.2/-0 sec./day.
