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.
Set the POWER to OFF then, while holding down the REMOTE
POWER key, set the MAIN POWER key to ON.
•Please note that resetting the microcomputer clears the contents
stored in it and returns it to the condition when it left the factory.
