Error code 14-01 is serious. It is a bad eprom checksum error in the Central Control Computer. This can affect operation of the whole jukebox. You will probably have to ship your CCC off to a repairman like Bruce Wentworth.
Error code 06-02 is nothing bad. It means that the V1 sensor in the dollar bill acceptor was covered too long, perhaps from a torn dollar bill. It's probably ok now and nothing to worry about.
Bruce is probably the last guy out there who can repair CDM4 players, provided he still has spare parts. The CDM4 player went obsolete 20 years ago and repair parts are now impossible to find.
