Adjusting PA calibration manually
It is possible to calibrate the duplex performance of the conference phone when it
is connected to a PA system. The calibration level can be set automatically by the
OmniTouch 4135 IP or adjusted manually to any value between 0 and 5 (0 being full
duplex).
• Increase the calibration if the other party experiences disturbing echo.
• Decrease the calibration if the other 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 amplier’s set-
tings may affect full duplex performance.
Select MENU > PA > CALIBRATION.
AUTO is the default setting and is recommended in most cases. The gure shown in
brackets is the measured calibration value.
Select different levels and compare the audio quality to achieve your preferred setting.
NB. You must ask the person you are calling to assess the effect of the adjustments
you make.
