Communications Errors and Their Remedies
Message
This section describes the errors relating to communications that can occur
during operation, and their remedies.
When a communications error occurs, the error message is displayed at the
NT631/NT631C, and the buzzer sounds, provided the setting made for Buzzer
Sound in the System Menu is other than OFF. An error message is displayed
provided the setting for the Comm. Auto-Return memory switch is not ON
(note that some error messages are displayed even if the setting is ON).
When an error message is displayed, after removing the cause of the error,
press the OK touch switch displayed on the screen. The NT631/NT631C will
return to the screen that was displayed before the error occurred, and opera-
tion will restart.
For communications errors, the name of the port at which the error occurred,
the error classification (send or receive error), the details of the error, the
probable cause, and the remedy, are displayed as shown below.
Example:

nance mode.
