CD ADJUSTMENTS

CD PLAYER ADJUSTMENT PROCEDURES Adjusting Conditions:

- Test disc: Sony YEDS-18

- Pre-operating : Push open/close key to open the CD tray. Load test disc YEDS-18, then push this key once against to close tray.

- Oscilloscope:

1) Adjustment of E/F balance

- After TOC. push play/pause key once to play and push SEARCH key to search.

- Connect the scope between the measurement points.(TSO , V-CEN)

- Then adjust the VR701 until A=B( as figure A)

2) Adjustment of RF (EYE PATTERN)

- After TOC. push play/pause key once play.

- Connect the scope and Jitter meter between the measurement points (RF , V-CEN)

- Adjustment VR702 until the wave form of eye pattern. Become may or jitter value MIN. (as Figure B)

DECK "A"

HEAD AZIMUTH ADJ.

1. Connect two (2) VTVMs and a dual trace scope to the stereo headphone Jack (as shown) with a 32 ohm dummy load.

PUSH

(See Figure 1 )

Figure1. Azimuth Adjustment

2. Insert a 8 kHz test tape into the tape mechanism and play it back.

3. While playing back the test tape, slowly turn the azimuth adjusting screw until the amplitude of both channel output waveforms is maximum and inphase. (See Figure 2 )

4. Secure the azimuth screw in place with glue or paint after making the adjustments.
