Reset Factory Settings (Initialize CD's)
To reset factory settings, Turn off jukebox power, Press and hold MEMOREC RESET and MEMOREC ADVANCE switches, Turn on jukebox power.
You should see Error 0 (means default settings loaded).
To reset errors, set switch to Service Mode and enter 699.
To initialize CD's, set switch to Service Mode and enter 777, four dashes will appear on the Central Control Computer display. CD activity should begin within a few seconds. Each disc is loaded and about 2 seconds of each track is played. The dashes will disappear after CD's are initialized (or after 30 seconds if no CD changer activity).
If your CD changer fails to initialize (won't allow the first digit number 5) or doesn't play songs correctly, you may have the wrong CCC program version. Different versions were produced for the Pioneer 6-disc changers, and later on, the Sony 10-disc changer. Some EPROM program versions didn't support any CD changer.
