Q:
I see an unusual light pattern on my JBL LSR 4300 speakers: the RMC button is 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 No Mic Found, which is caused if the RMC mic is not connected during RMC calibration.

To remedy this, press [RMC] to exit RMC mode. Connect the mic, then press and hold [RMC] to calibrate.
