The table hereafter gives the CAS messages and the status light colors
corresponding to the state of the system.

is displayed in the CAS window if the engine is shutdown with
PROP DE ICE switch still ON.
CAUTION
When the engine is shutdown, do not set the PROP DE ICE switch to ON for
more than 10 seconds, damage to the propeller blades could result.
Windshield Deicing
The windshields are electrically deiced by integrated heating resistors. The system
includes two controllers and two heat probes embedded in each windshield. They
are operated by the WINDSHIELD switch.
When WINDSHIELD deice system is activated either manually or automatically,
the controllers supply the heating resistors, the windshield temperature is
controlled via heat probes. When the temperature reaches 45 °C (113 °F), the
controllers cut the electrical supply to the heating resistors and resume supply
when the temperature falls below 30 °C (86 °F). The cycle continues as long as
the system is activated.
In the event of failure of probe 1, the controller receives the temperature data from
probe 2. The electrical supply to the heating resistors is cut when the windshield
temperature reaches 56 °C (133 °F). In that case, the windshield is no longer
heated, the pilot can reset the system by setting the WINDSHIELD switch to OFF,
then to ON.
