following points and then contact the Mitsubishi Service Center.

[Precautions]
If the outdoor temperature is 5°C or less, the NC may not start up. However, warmup operation is
carried out by warming up the HDD with the heater to protect the HDD from low temperatures.
Check the warmup operation sign with the LEDs on the operation board. (Refer to the operation
board manual issued by each machine maker.)
The NC will start up automatically when the warmup operation is completed.
