What do CD error codes Error-07, Error-11, Error-12, Error-17, and Error-30 mean?

These error codes indicate that the disc is either dirty or scratched. Clean the disc if it is dirty, or replace it if it is scratched. If error codes Error-07, 10, 11, 12, 15, 17, 30, or A0 appear, there may also be an electrical or mechanical error — turn the ignition switch OFF and back ON, then return to the CD player. (Page 40)
