Operation to reset

The microcomputer may fall into malfunction (impossibility

to operate, erroneous display, etc.) if the power cord is

unplugged while power 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.

Unplug the power cord from the power outlet then, while

holding the SET (¶) key depressed, plug the power cord

again

¶Please note that resetting the microcomputer clears the

stored contents and returns to the factory set condition.
