EX5000 Release 8.2.2 Installation Manual

•
Enable geo stabilization – an external position source (GPS or FMS) connected to the sensor will
stabilize the lightning strikes to the aircraft position
•
Enable heading stabilization – an external heading source (e.g., a synchro) connected to the
sensor will stabilize the lightning strikes to the aircraft heading.
•
Enable Audio Output – if connected to the aircraft audio panel, the TWX-670 will provide audible
warnings concerning nearby lightning strikes.
These options are only available after the Sensor and Port options have been selected
and the MFD restarted. Green check marks will appear next to each option if the TWX-
670 agrees with the configuration. If red X’s appear, it may be because another display
connected to the sensor is trying to set a different configuration. Consult the TWX-670
installation manual for more information.
