5 disassembly instructions caution before starting servicing electronic parts are susceptible to static electricity and may easily damaged, so do not forget to take a proper grounding treatment as required. many screws are used inside the unit. to prevent missing, dropping, etc. of the screws, always use a magnetized screw driver in servicing. several kinds of screws are used and some of them need special cautions. that is, take care of the tapping screws securing molded parts and fine pitch screws used to secure metal parts. if they are used improperly, the screw holes will be easily damaged and the parts can not be fixed. cabinet disassembly 1. top case 1) release 7 screws (a).

1. the unit turns to karaoke mode with ou-screen lyrics display and melody sound when it play backs vcd or dvd karaoke disc. 2. if a microphone is connected at this time, micom recoguizes the connection and prepares the composition of external voice and internal melody. 3. the week signal of the microphone is converted to the digital signal after voice output that has passed through preamp(ba3308 ) and amp(kia4558) passes through (cs5331) that is audio adc(analog to digital convertor). 4. this digital signal enters c-cube that is mpeg ic and is added to the output of dvd dsp (p-processor). 5. this mixed signal is output to av jack after passing through audio dac(pcm1716).
