1. Check that the power supply upstream of the system is working properly
2. Check that the power cord is properly plugged
3. Check that the ON/OFF selector is turned to "I".
The speaker turns on but it doesn't output any sound:
1. Check that the input connections of the main audio signal and of the auxiliary one, if any, have been
performed properly
2. Check that the cables in use are not damaged
3. Check that the mixer or the audio source are on and that they clearly indicate the presence of an
output signal to the speaker.

value
The speaker outputs a distorted sound:
1. Adjust the source volume first, then set the ES 602 or ES 802 system input volume to an appropriate
value
2. Check that the cables in use are not damaged; should that be the case, replace them (a damaged cable
may result in a signal loss or alteration)

1. Turn off the system and disconnect the audio connection between the subwoofer and the satellites
2. Check the integrity of the audio cable used for the connection
3. Uninstall and properly reinstall the 2 satellites A and B, checking that there are no mechanical
clearances.
