When one or more of the error displays listed below appears on the LCD monitor of the remote control, refer to the
troubleshooting procedure that corresponds to that error display. When there are multiple errors that occur at the same time, the
main error will only display.
In this case, after troubleshooting the main error that was displayed, if you operate the remote control again, any secondary or
remaining errors will display. Follow the troubleshooting steps for the error(s).
