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.

3.JITTER CHECK 1) While oscilloscope is kept connected in the same test point as in step2. RF WAVEFORM CHECK, connect the output terminal of an oscilloscope to the input terminal of the jitter meter. 2) 3) 4) Set the VOLT range selector of oscilloscope to 500mV range or below. Play back 2nd track of TCD-782.

Check that jitter meter indicates 28.0ns or less.

4. PLAY ABILITY CHECK 1) Play back the 3rd , 8th and 13th track of ATD-001. Check that the noise does not occur sound skipping does not occur.
5.LASER CURRENT CHECK *Do not perform this measurement unless the laser is suspected to be defective. 1) 2) 3) Connect digital multi-meter across the resistor R402(10Ω). Play back the TCD-782 and check the DC voltage value on the digital multi-meter. Calculate the laser current (Iop) by dividing the DC voltage across R402 by the resistor value (R402= 10Ω). Check that the laser current (Iop) is 60mA or less.
