8.1 MSO3xx Man Machine Interface
8.1.1 Description
In addition to the sensor light, there are two LEDs to provide information to the user:
 when the sensor light is on, it usually means that the device is waiting for the user to
place a finger on the sensor,
 the upper led is mainly used for smart card reader status (MSO35x only),
 the lower led is mainly used for biometric process status.
The tables below describe the meaning of the light signals.
