SETTINGS DURING A CALL
The HEADSET/PA, PHONE BOOK, TRANSFER and EQUALIZER menus may be ac-
cessed during a call and are displayed when the
MENU button is pressed. The first
option is either HEADSET or PA depending on whether PA is activated or not.
 These HEADSET/PA settings can only be accessed when a call is connected.
Turn off the internal speakers when using a headset
 PA should not be activated when using the HEADSET menu option.
A wireless headset can be used if a person needs to move far away from the conference
phone (e.g. during a seminar or presentation). The internal speakers can be turned off
temporarily if you wish to use the Avaya B179 as a personal telephone with a headset.
 Select MENU > HEADSET.
 Select YES when asked “SPEAKER OFF?”.
 The speakers come on automatically when the call is ended.
Adjusting microphone volume from PA system
 PA should be activated when using the PA menu option.
 Select MENU > PA > PA MoNIToR.
 Adjust the microphone volume from the mixer so that the level on the display screen
is around 10–12 when speaking in a normal tone.
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 Avaya
B179 or adjusted manually to any value between 0 and 5 (0 being full 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 set-
tings may affect full duplex performance.
 Select MENU > PA > CALIBRATIoN.
