Open, if no authentication mechanisms are set, any user can use the device. User has logged into the device—if users exist, it indicates that the device has authenticated a user.
The flash frequency is approximately once per second and indicates that the device is waiting for a finger due to one of the following situations (H200 Only
• The device has just been plugged in and no user is currently logged into the device.
• Software has initiated a biometric authentication or enroll operation.
• A user has initiated a finger authentication operation for example, by touching the device when it is in the “idle” waiting for-finger state. A device will remain in an idle state for only two
minutes before the LED turns red to indicate the device is locked.
Flashing red once:
Failed fingerprint authentication attempt. The device will go back to waiting for a finger (flashing green normal) after the failed signal finishes.
Flashing LED alternating between red and green:
The device is waiting for a finger to authenticate but this is also the last chance to authenticate before biometric access is blocked. The frequency is approximately twice per second.
The device is either powering up or is totally blocked. When totally blocked, no authentication methods are available to allow a user to log into the device; this indicates that the device needs
to be recycled or reset.
The device is locked.
Indicates a data transfer activity for all devices.
Flashing red and blue:
Indicates that a fatal internal error has occurred.
Sufficient power from the host computer is available and the device is operating normally.
Flashing yellow (slow):
Insufficient power to operate the device. Attach both USB connectors to the host computer. If both connectors are already plugged in, and the LED continues to flash, the host computer
does not meet the USB power requirements.
Flashing yellow (fast):
Power detection has timed out. Unplug all USB connections and reconnect the them.
No Yellow LED
No power is detected. Device is off.
H300/H350/H400: This also may indicate that the device has been self-destructed
