MP-310 Invalid front panel keystroke combination

The MP does not recognize the command. An illegal command was entered through the MP front panel keypad on an MP-30/35 system.

This error only occurs when you use the MP front panel on an MP-30/35 system.

What you should do:

  1. To clear the error, press the MP CLEAR key on the MP front panel.

  2. Enter a valid command. The mistake may be caused by operator input.

  3. If the system gives the error message again confirming that the function is illegal, use a legal function.
