The changes in the menu take effect immediately if the device is 
attached. The active voice path switches to the selected headset if you 
are on an active call. If you press the 

 context-sensitive soft key, 

then the changes are applied, the settings are made permanent by 
storing the values in persistent storage, and they are applied every time 
the IP Deskphone starts up. However, all changes made are ignored and 
restored if you press the 

 context-sensitive soft key. 

On the 

 menu, choose 

, and then select 

 

to verify the presence of the USB headset attached to the IP Deskphone. 
When you select the 

 menu, the attached USB headset is displayed 

along with other USB devices. The name of the USB device directly 
appears from the USB devices themselves. The product description has 
no explicit USB headset indications for the attached USB headset. The 
following figure displays the headset setting screen.

MHA Back Light

Enable the MHA Back Light (only 
if Avaya headset adapter is

The checkbox is used to enable 
or disable the back light 
equipped in Avaya Enhanced or 
Mobile headsets. The command 
is ignored for other types of USB 
headsets. This item is dimmed if 
the attached headset is not one 
of the Avaya headset types.
