Complete and very useful. Could have benefited from a little higher resolution on the schematic and layout diagrams for improved legibility.

This manual is complete and very readable.It was a great help for my two ICF5800L.The first one had the dial cord broken,and without the service manual it is impossible to replace it.Thank.Olivier.

This is a top quality manual. You couldn't get better if you had the original and scanned it yourself. Best price on the net as well. Diagrams are clear and complete, text is sharp and easy to read. Granted you don't get the manual the second you click pay, but the few hours you have to wait for it to be available for download isn't a problem at all. This is a very reliable company.
Very VERY pleased with the product, and will buy others. Thanks!
