Voice Volume Keys

Use the Volume Up ( ) and Volume Down ( ) keys

on a call, press to raise the volume of the voice you
are hearing, or press to lower the volume of the
voice you are hearing. Press either key until you reach
the desired voice level. When you hang up or switch
to another call, the voice volume returns to the default
level.
