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 con­tents 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.
