Headset consideration
Test the headset with the telephone before use. In a noisy environment, an amplified headset is
an option. When using the amplified headset, there are two choices of volume control: the
rocker control on the telephone and the switch on the headset. The user should adjust the
telephone volume, before adjusting the headset volume. To provide the best communication
with the least amount of distortion, the amplifier should have a higher setting than the telephone
volume control.
Refer to your representative for the latest product bulletin from Avaya recommending headset
types for use with the Avaya 3900 Series Digital Deskphone.
