There are connectors for the headset and the headset-microphone
on the left side of the socket, when viewed from the front – see Fig.
The little switch is used to toggle between the system’s own
speakers/microphone and the headset’s.
If you connect headset only (no microphone) the toggling will be
between the systems’s loudspeakers and the headset’s.
If you connect headset and mic., the toggling will be between the system’s
speakers/microphone and the headset’s.
If you connect a microphone only (no headset), nothing will happen
