AUTO or CARBON Setting
There exist two types of headsets: ECM and Carbon. The default setting on the
telephones is AUTO. When the headset is connected to the Headset Modular
Connector of the telephone, the AUTO setting enables the headset I/F current detector
to determine which headset type is connected (EMC or Carbon). If the current is
marginal using a carbon headset (only) and performance is not good, change the
setting to CARBON.
