6、ovementBefore 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 shownappears.3. Set the POWER key to OFF.Beware of condensationWhen the difference between the internal temperature

7、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 up.Be especially careful in the following conditions:When the unit is brought into a place where the

8、re is a large differ-ence in temperature between the previous location, when thehumidity of the listening room is high, etc.The marking is located on the rear panel and says thatthe component uses laser beams that have been clas-sified as Class 1. It means that the unit is utilizing laserbeams that

9、are of a weaker class. There is no danger ofhazardous radiation outside the unit.CLASS 1LASER PRODUCTThe marking of products using lasers(Except for some areas)Operation to resetThe microprocessor may fall into malfunction (impossibility to oper-ate erroneous display, etc.) when the power cord is un
