Automatic volume control (Menu 4-1-1)
Automatic volume control (AVC) controls the earpiece’s volume level according to the environment
noise level. If the environmental noise and/or level of received speech increases or decreases, AVC
changes also the earpiece’s volume level accordingly and keeps the volume at a right level respectively.
Automatic volume control can be activated by using menus or you can select it during an active call.
Note: AVC on/ AVC off setting during an active call affects only the current call.
Note: The usage of Automatic volume control is possible only in handportable mode. If you are using
the phone in any other modes (for example in Headset mode or in Handsfree mode) the options AVC
on/ AVC off cannot be selected during a call under
Options
or through the menu.
