Operation to reset

The microcomputer may fall into malfunction (impossibility

to operate, erroneous display, etc.) when 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.

Please note that resetting the microcomputer clears the con-

tents stored in and returns and to condition when it left the

factory.

Set the POWER switch to ON (set to Standby

mode). Then press the key, key and STOP

key in this order.
