Adjusting PA calibration manually
If needed it is possible to calibrate the full duplex performance. The calibration value can be set
to AUTO or be adjusted manually in steps from 0 to 5 where 0 is the highest grade of duplex.
• Increase the calibration if the remote party experiences disturbing echoes.
• Decrease the calibration if the remote party experiences low duplex, i.e. your voice is muted
or clipped when the other party is speaking.
 The position of the PA system's microphones and speakers and the amplifier's settings may
affect full duplex performance.
