The microcomputer may fall into malfunction (impossibility
to operate, erroneous display, etc.) when the power cord is
unplugged while unit is ON or due to an external factor. In
this case, execute the following procedure to reset the
microcomputer and return it to normal condition.
• Please note that resetting the microcomputer clears the
contents stored in and it returns to condition when it left
the factory.

Unplug the power cord from the power outlet then, while
holding the menu/demo key depressed, plug the power
cord again.
