<Flashing Error Codes>
If the ON lamp and error code are both flashing: This means that the unit is out of order and operation has been stopped (and cannot resume). Take note of the indicated unit
number and error code, then switch off the power to the unit and call your dealer or servicer.
If only the error code is flashing (while the ON lamp remains lit): Operation is continuing, but there may be a problem with the system. In this case, you should note down the
error code and then call your dealer or servicer for advice.
* If you have entered contact number to be called in the event of a problem, push the Check button to display it on the screen. (You can set this up under Function Selection of
remote controller. For information, refer to section 6.)
