Trouble shooting 

 
CUT-OUT WHILE THE UNIT IS IN USE : 
Your Explorer 150 has a protection handled by the 
micro-processor. In the case of a problem with the 
power section (short-circuit/overload/etc), the fuses 
situated on the supply, cut out. This is then detected 
by the micro-processor that handles the 150, which 
then passes automatically onto the protection mode 
in less than a millisecond. 
At this moment, all the lights will shut down, 
including the gain numbers on the volume window. 
This signifies a fault in the unit : please contact your 
dealer or Kora directly. 
This may happen the first time you fire up the unit 
and is due to the fact that the supply is not yet 
loaded. The remedy is simply to turn off the unit by 
the switch on the rear plate, wait until the micro-
processor has been reset and then turn on the unit 
again. 
If the problem persists, please contact your dealer.
