of controls or adjustments or performance of proceduresother than those specified herein may result in hazardous radiationexposure.UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards 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 solder 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 flow)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.Notes on chip component replacementNever reuse a disconnected chip component.Notice that the minus side of a tantalum capacitor may bedamaged by heat.Flexible Circuit Board RepairingKeep the temperature of the soldering iron around 270 Cduring repairing.Do not touch the soldering iron on the same conductor of thecircuit board (within 3 times).Be careful not to apply force on the conductor when solderingor unsoldering.SAFETY-RELATED COMPONENT WARNING!COMPONENTS IDENTIFIED BY MARK 0 OR DOTTED LINEWITH MARK 0 ON THE SCHEMATIC DIAGRAMS AND INTHE PARTS LIST ARE CRITICAL TO SAFE OPERATION.REPLACE THESE COMPONENTS WITH SONY PARTS WHOSEPART NUMBERS APPEAR AS SHOWN

Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” and checkthat the S curve waveform is output several times.DISC SLOT LOCKThe disc slot lock function for the antitheft of an demonstrationdisc in the store is equipped.Setting Procedure :1.Press the ?/1 button to turn the set on.2.Press the FUNCTION button to set DVD function.3.Insert a disc.4.Press the x stick and the A button simultaneously for fiveseconds.5.The message “LOCKED” is displayed and the slot is locked.Releasing Procedure :1.Press the x stick and the A button simultaneously for fiveseconds again.2.The message “UNLOCKED” is displayed and the slot isunlocked.Note:When “LOCKED” is displayed, the slot lock is not released byturning power on/off with the ?/1 button.Note 1:Regarding the notification symbol “R”Because the number of the operating buttons of this product arelimited, some operations require use of the operating buttons ofthe remote commander, When a specific operation requires useof the operating buttons of the remote commander, “R” is addedto the specific operating procedure in this manual.Example MENU/NO “R” The MENU/NO button of remotecommander.Note 2:Incorrect operations may be performed if the test mode ia notentered properly.In this case, press the ?/1 button to turn the power off, andretry to enter the test mode.Note 3:If the disc tray does not open and the message “LOCKED”appears, press the x stick and the A button simultaneouslyfor seconds or longer.Then remove your fingers from the above stick and the button.The message “UNLOCKED” appears for 2 seconds and the disctray opens.Note on DMB10 board replacementNew part of EEP ROM (IC103) on the DMB10 board cannot beused. Therefore, if the mounted DMB10 board (A-1108-644-A)is replaced, exchange new EEP ROM (IC103) with that usedbefore the replacement.When the self-diagnosis function is activated to prevent the system from malfunctioning, a 5-character service number (e.g., C 13 50) with a combination of a letter and 4 digits appears on the screen and the front panel display. In this case, check the following table.Self-diagnosis Function (When letters/numbers appear in the display)First 3 characters of the service numberCause and/or corrective actionC 13The disc is dirty.,Clean the disc with a soft cloth C 31The disc is not inserted correctly.,Restart the system, then re-insert the disc correctly.E XX(xx is a number)To prevent a malfunction, the system has performed the self-diagnosis function.,Contact your nearest Sony dealer or local authorized Sony service facility and give the 5-character service number.Example: E 61 10C:13:505HCD-DZ500F SERVICE POSITION (DMB10 BOARD)When servicing side B of the DMB10 boardRemove the DMB10 board from bracket.(Refer to DISASSEMBLY 3-6.
