Q:
I see an unusual light pattern on my JBL LSR 4300 speakers: all of the buttons are blinking and the meter is lighting sequentially from right to left. 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 RMC-Timeout, which is caused if the RMC process fails to complete.

To remedy this, power-cycle the speakers (turn them off and back on), then perform RMC again. If the problem persists, perform the factory reset procedure and repeat the RMC calibration process.
