Error A command failed due to other circumstances. The most likely cause is
that the serial interface did not execute the “KB 1” command to lock-out keyboard
control, and someone is using the front panel controls. This message can also be
caused by a parameter out of range.
Error --Range The following commands have a parameter out-of- range:
• TN
• ANID
• AUTOSTART
• C 10
