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.

Great quality copy, right what I was looking for, all I need to fix my radio.

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.
