A crackling noise may be heard. Some smart phones and other transmitting devices used near the unit may cause
interference and noise in amplifi er output. Shutting down transmission by setting a smart
phone to airplane mode may often minimize noise from interference.
A number is displayed after "ER"
appears, then the unit is shut down
and cannot be turned on again.
Note down the number, disconnect the power cord and contact customer support.
"OL" is displayed, the sound volume
drops or the unit is shut down. This happens when the protective function is triggered after detecting an excessive signal
output in headphone output.
Lower the sound volume and check for short-circuits in cables and jacks.
