VAA Sensitivity Level
This is the volume level of the order taker’s voice required to activate the VAA circuit. During normal
operation, the inbound audio level should be reduced when the Order Taker speaks to the customer,
and should recover when the Order Taker stops speaking. If speaking to the customer does not
automatically reduce the inbound level, press the VAA sensitivity button and then press the + and −
buttons to adjust sensitivity to the Order Taker’s voice.
VAA Attenuation Level
This is the amount that the inbound volume level is reduced when the Order Taker speaks to the
customer. The attenuation level is factory set at 15dB, and should not require adjustment.
If the Order Taker cannot hear the inbound audio at all while speaking, the VAA attenuation can be
adjusted to a lower level. To make this adjustment, press the VAA attenuation button and then press
the + and − buttons until the desired level is reached. If you do not want any attenuation, please just
turn off VAA without adjusting this setting.
See Audio Processing Functions, pg. 60, for more information on VAA.
