(Accessory only for regions where use is necessary.) Note related to transportation and move- ment Before transporting or moving this unit, carry out the follow- ing operations. 1. Set the POWER key to ON without loading a disc. 2. Wait a few seconds and verify that the display shown appears. 3. Set the POWER key to OFF. Beware of condensation When the difference between the internal temperature of the unit and external atmosphere is large, dew (mist) may be produced on the internal parts of the unit. In such a case, turn the unit ON and leave it for a few hours until the condensation has dried up. Be especially careful in the following conditions: When the unit is brought into a place where there is a large differ- ence in temperature between the previous location, when the humidity of the listening room is high, etc. Operation to reset The microprocessor may fall into malfunction (impossibility to oper- ate erroneous display, etc.) when the power cord is unplugged while power is ON or due to an external factor. In this case, exe- cute the following procedure to reset the microprocessor and return it to normal condition. 1 In POWER ON condition, keep the 7 (STOP) key and the ON/STANDBY key pressed at the same time. 2 When both keys are pressed, the region code of the unit, the software version, etc. will be displayed on the display. (When nothing is done, the display of this information continues.) Example: 71 . 101 . 06:14 3 Press the ON/STANDBY key to go to STANDBY mode. 4 When Power ON is performed with the ON/STANDBY key, the settings become the default factory settings. Please note that resetting the microprocessor clears the con- tents stored in, it returns the microprocessor to the condition when it left the factory.
