I have not had much experience with the CX20 other than the one I have here that I can't get running. However we had some other Mitsubishi EDMs with the same control. Usually when they did something strange we had to reload the software. This seemed to be a frequent problem with all our Mitsubishi EDMs. Every 6 months to a year they would need to be reloaded. Other then that I can't help much. |
