    Why does Mitsubishi G-50A display the message 'G50 can't Connect to SMTP Server ! or G-50 Date Setting is wrong !! Continue ?'?
    • S
      Sydney LittleAug 27, 2025
      This message appears because the dial-up router is either not connected or incorrectly configured, the default gateway of G-50A is not set, the receiver address is incorrectly displayed by SMTP, or the Monitor Finish Date is older than the current date/time of G-50A. To resolve this, connect or correctly configure the dial-up router, set the default gateway using the G-50A initial setting tool, enter the correct mailing address, and set the monitor finish date correctly, considering any time differences in the region.

    Why are all the characters red on the monitor display for some units in Mitsubishi G-50A?
    • J
      Jocelyn GarzaSep 18, 2025
      If all the characters on the monitor display are red for some units, it indicates there is no response from the unit, meaning the software cannot communicate with it. This is an error with the unit and you should refer to the service handbook for that unit.
