There is a comprehensive Error Messages and Trouble Shooting guide (Appendix F) included in the owner's manual for the LSR subwoofer and the new 2.0 owner's manual for the 6" and 8" speakers. If you see an unexpected light pattern on the meter display of any speaker, or if the speaker is not operating as expected, Appendix F will tell you the cause and the corrective action.

You can also find articles about these light patterns in our Knowledge Base. Simply search for the Item ID of your JBL speakers.
