If condensation occurs, correctoperation may not be possible, or the unit may not function correct-ly. This is not a malfunction, however, and the unit should be dried.(To do this , turn the POWER switch ON and leave the unit for sev-eral hours.)Be especially careful in the following conditions:*When the unit is brought from a cold place to a warm place,and there is a large temperature difference.*When a heater starts operating.*When the unit is brought from an air-conditioned place to aplace of high temperature with high humidity*When there is a large difference between the internal tempera-ture of the unit and the ambient temperature, or in conditionswhere condensation occurs easilyCaution * Please refer to KX-W594/W1060 Service Manual (B51-4924-00) if you want to know disassembly andmechanism operation.CT-201/KXF-W1010(K) 1p 98.4.25 11:42 AM yW3No.ITEMINPUTSETTINGSOUTPUTSETTINGSCASSETTE DECKSETTINGSALIGNMENTPOINTALIGN FORFLG.CASSETTE DECK SECTIONTAPE: NORMAL, DOLBY: OFF, INPUT: LINE IN0 dBs = 0.775 VI.
