Q:
I see an unusual light pattern on my JBL LSR 4300 speakers: all of the front-panel buttons and the meter are flashing rapidly. What does this mean?
 
A:
This light pattern indicates an error. You can look up these errors in Appendix F of the LSR User's Manual.

This particular error is Reset, which is caused when a non-standard DIP switch configuration is used to restore the speaker's factory settings. This mode is entered by setting all DIP switches to "On" and re-powering the speaker.

To remedy this, reset the DIP switches so only a single DIP switch is active on each speaker and re-power.
