TROUBLESHOOTING LIST

Condition

No Meter Display

The speaker will not output any audio, and the solo light on the front is blinking.

I just fi nished connecting my system, but there is no audio.

I selected my digital input, but the audio keeps dropping out.

I am having trouble daisy- chaining my digital audio through multiple speakers.

My remote control doesn’t work all of the time.

My speaker will not power up. There are no lights at all anywhere on the speaker.

Upon boot –up, LSR4300 Control Center Sofware does not “recognize” connected speakers.

Cause

Lack of network terminators

DIM button on Remote Control is activated

Brightness control is turned down

The Speaker is in SOLO mode.

Input selection is not set to match input source.

Poor connection, defective cable, or source is unstable.

Cable may not be suitable for digital application.

Batteries weak.

Remote is not pointed at the receiver.

Speaker is not connected to power source or fuse is blown.

USB connection and/or Network cables not properly connected.

Missing terminator.

Remedy

Install terminators in fi rst and last speaker.

Press DIM button on remote control to restore full volume. Caution – To prevent sudden jump in volume, lower the system volume setting prior to deactivating DIM control.

Use the brightness control or hold +/- to enter the brightness mode, and push + until you have the brightness level you like.

In a networked system, press SOLO on the speakers that have their SOLO button blinking. If your system is no longer networked and the speaker is still muted, hard reset your loudspeaker.

Make sure your input selection matches the inputs you are using (Analog, S/PDIF, AES/EBU).

Check connections and cables. Confi rm you are using suitable cable of proper impedance. If cables and connections are OK, source may be unstable.

Make sure you are using cables per the

S/PDIF and AES/EBU specifi cation as described on page 39 in this manual.

Make sure remote is pointed at the Front Left speaker (the speaker with LEFT DIP switch in the ON position).

Confi rm your speaker is connected to an active power source.

Check the fuse. If blown, replace with the spare provided in the fuse holder in the IEC power connector. If speaker fails to power-up please call JBL Customer Service.

Check all network connections to make sure the CAT5 cable is inserted all the way into each jack.

Make sure you have two network terminators installed in your system so that all RJ485 jacks are in use. Confi rm the USB cable from your computer is connected to the front left speaker (the speaker with LEFT DIP switch in the ON position).
