Precautions
• Check the target model and obtain the firmware update file that matches with the target model from your local Mitsubishi
representative. The firmware update cannot be executed if the firmware update file does not match with the target model.
• Do not modify the data (folder name and file name) obtained from your local Mitsubishi representative.
• Do not power off or reset the CPU module during execution of the firmware update. If the CPU module is powered off or
reset before the firmware update is finished, execute the firmware update again.
• Do not remove the SD memory card from the CPU module during execution of the firmware update. If the SD memory card
is removed from the CPU module before the firmware update is finished, the firmware update may fail.
