Set the POWER key to ON without loading a disc.2. Wait a few seconds and verify that the display shownappears.3.
6、Set the POWER key to OFF.Beware of condensationWhen the difference between the internal temperature of the unitand external atmosphere is large, dew (mist) may be produced onthe internal parts of the unit. In such a case, turn the unit ON andleave it for a few hours until the condensation has dried
7、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 thehumidity of the listening room is high, etc.Operation to resetThe microprocessor may fall into malfunction (impossibilit
8、y to oper-ate erroneous display, etc.) when the power cord is unpluggedwhile power is ON or due to an external factor. In this case, exe-cute the following procedure to reset the microprocessor andreturn it to normal condition.1 In POWER ON condition, keep the 7 (STOP) key and the (Search) key press
9、ed at the same time.2 When both keys are pressed, the region code of the unit, thesoftware version, etc. will be displayed on the display. (Whennothing is done, the display of this information continues.)Example: 71 . 101 . 06:143 Press the ON/OFF key to go to Power OFF.4 When Power ON is performed
10、with the ON/OFF key, the set-tings become the default factory settings. Please note that resetting the microprocessor clears the con-tents stored in, it returns the microprocessor to the conditionwhen it left the factory.CautionsDV-502/503/DVF-3050/35502CONTENTS / ACCESSORIES / CAUTIONSCONTENTS / AC
