6、t Replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may bedamaged by heat.z UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boa

7、rds may not come printed withthe lead free mark due to their particular size): LEAD FREE MARKUnleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higherthan ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the s

8、older joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350 C.Caution: The printed pattern (copper foil) may peel away ifthe heated tip is applied for too long, so be careful! Strong viscosityUnleaded solder is more viscou-s (sticky, less prone to f

9、low)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc. Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.TABLE OF CONTENTS1.SERVICE NOTE.32.GENERAL.43.DISASSEMBLY3-1.Case (Front) Assy .53

12、 to perform theBAD BLOCK check* and writing of the model code. If they are notcompleted, the unit will not operate normally. * BAD BLOCK check is to check the flash ROM memory area(the BAD BLOCK area) where data cannot be guaranteed.The resultant information of this check is stored in the TOC-AREA s

13、o that the BAD BLOCK area should not be used.BAD BLOCK Check Procedure1.When the power is turned on after the flash memory (IC701)is replaced, the BAD BLOCK check starts automatically andthe OPR (D701) lights in orange.2.In about 30 seconds after start of the check, the OPR (D701)changes the color t
