This manual is very useful because it presents the technical specifications of the cd player, including the manufacturer of the reader, this helps if you need to replace it. It also displays the settings and layout of the circuit.

Manual was a good representation of service infomation for the EWV404. It worked well for my repair.

I BOUGHT A PAIR OF INFINITY VINTAGE SPEAKERS THAT REQUIRED TO BE REPAIRED AND THE ELECTRONIC TECHNICIAN ASKED ME FOR THE SERVICE MANUAL.
I TRIED TO GET IT AT THE MANUFACTURER'S SITE WITH NO SUCCESS, SO I STARTED TO LOOK FOR IT IN THE WEB FOR A LONG TIME, UNTIL I FOUND THE SERVICE MANUAL IN THIS EXCELLENT SITE "OWNER'S MANUAL.COM".
NOW I HAVE MY SPEAKERS WORKING AND ENJOYING THE MUSIC I LIKE.
THANKS TO "OWNER`S MANUAL.COM" I RECOMMEND THIS SITE TO EVERYONE.

Very quick response. Very good and accurate print quality of the scanned document.
CONVERGENCE ADJUSTMENT
CENTER CONVERGENCE ADJUSTMENT
1. Connect a crosshatch generator to antenna terminals. 2. Set Contrast control to low level to eliminate Blooming. Reduce Brightness level to obtain black background if necessary. 3. Adjust the angle between the four-pole magnet tabs 1 and 2 (Figure 2), and superimpose the red and blue vertical lines in the center area of the picture screen. See Figure 4. 4. Keeping the tabs at the same angle, rotate them together to superimpose the blue and red horizontal lines in the center area of the picture screen. See Figure 4. 5. Adjust the six-pole magnet tabs 3 and 4 so the converged red/blue line is superimposed on the green line. This is the same procedure used in Steps 3 and 4. See Figure 5.
OUTER AREA CONVERGENCE ADJUSTMENT
The outer area convergence is performed by positioning of the yoke as follows: 1. Move the top of the yoke toward or away from the picture tube. This movement will affect the vertical lines at the top and bottom and the horizontal lines at the sides. See Figure 6. 2. Check that splits at 12 O�Clock and 6 O�Clock positions are minimized, adjust yoke for best compromise. Secure with wedge at 12 O�Clock position. See Figure 1. 3. Move the side of the yoke toward or away from the picture tube to converge the horizontal lines at the top and bottom and the vertical lines at the sides. See Figure 7. 4. Check that splits at 12 O�Clock and 6 O�Clock are minimized, adjust yoke for best compromise. Secure yoke position with the side wedges. See Figure 1. Note: When reusing the rubber wedges, apply a small amount of silicone rubber adhesive or hot melt to each of the wedges.
