SETTINGS DURING A CALL
The HEADSET/PA, PHONE BOOK, MOBILE LEVEL and EQUALIZER menus may be
accessed during a call and are displayed when the MENU button is pressed. The rst
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 Konftel 300 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 PA calibration manually
It is possible to calibrate the duplex performance of the conference phone when it is con-
nected to a PA system. The calibration level can be set automatically by the Konftel 300
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 amplier’s settings
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.
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.
