CAUTION: DO NOT MOVE PARTS OF THE CABIN FURNISHINGS UNTIL THE CABIN IS WARM.

CAUTION: DO NOT CONNECT EXTERNAL POWER TO THE AIRCRAFT UNTIL THE AVIONICS COMPARTMENT TEMPERATURE IS MORE THAN -15 DEG.C (5 DEG.F).

CAUTION: DO NOT OPERATE THE WINDOW HEAT UNTIL THE PROCEDURE TELLS YOU.

CAUTION: DO NOT BLOW WARM AIR DIRECTLY ON THE COMPUTERS IN THE AVIONICS COMPARTMENT. IF YOU DO, YOU CAN CAUSE DAMAGE TO THE EQUIPMENT.
