- In case of a whistle (feedback), first reduce the power of the microphone until an acceptable level is reached
Should whistle persist adjust the loudspeaker volume
Fault finding

Check for 12 V DC on terminal 12 +ve and terminal 1 -ve in the entrance panel
No call signal:
Ensure a link is inserted between 9 and 10 in the entrance panel
