Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantal

20、um capacitor may be dam- aged by heat. Flexible Circuit Board Repairing Keep the temperature of the soldering iron around 270 C dur- ing repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when solderi

21、ng or unsoldering. UNLEADED SOLDER Boards 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 with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded sold

22、er has the following characteristics. Unleaded solder melts at a temperature about 40 C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to

23、about 350 C . Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc.

24、Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. On power sources Use house current, LR6 (size AA) battery. For use in your house: Use the AC power adaptor supplied with this recorder. Do not use any other AC power adaptor s

Polarity of the plug 收音机爱好者资料库 Ra d i o Fa n s .CN 4 MZ-S1 NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electro- static break-down because of the potential difference generated by the c

26、harged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE

27、EMISSION CHECK Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight. NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-5R) The laser diode in the optical pick-up block may suffer electro- static break-down easily. When h

28、andling it, perform soldering bridge to the laser-tap on the flexible board. Also perform mea- sures against electrostatic break-down sufficiently before the op- eration. The flexible board is easily damaged and should be handled with care. (See Fig.1) Fig.1 OPTICAL PICK-UP FLEXIBLE BOARD SECTION 1

29、SERVICING NOTES laser-tap In performing the repair with the power supplied to the set, re- moving the MAIN board causes the set to be disabled. In such a case, fix a convex part of the open/close detect switch (S806 on MAIN board) with a tape in advance. Handle the FLEXIBLE board (overwrite head) wi

30、th care, as it has been soldered directly to the MAIN board. In repairing the component side of MAIN board, connect the FLEXIBLE board (overwrite head) and the MAIN board with the lead wires in advance. (See Fig.2) The shipment data will be cleared when the NV is reset. There- fore, change the NV ad

31、justed values following the Change of NV Adjusted Values immediately after the NV was reset. (See page 20) This set requires the patch data in the nonvolatile memory (IC804) to be rewritten using the application, when the MAIN board or nonvolatile memory (IC804) was replaced.

40、ebox with Windows 2000/Windows XP If your computer is Windows 2000 Professional, Windows XP Home Edition, or Windows XP Professional, please be aware of the following before instaling OpenMG Jukebox. 1 With Windows 2000 Professional, you must log on as “Administrators” (or with the user name “Admini

41、strator”) to install OpenMG Jukebox. 2With Windows XP Home Edition or Windows XP Professional, you must log on with user name “Computer Administrator” to install OpenMG Jubebox. To check whether a user name has the attribute of “Computer Administrator” or not, go to Control Panel - User Account. Not

42、es on using OpenMG Jukebox with Windows XP/ Windows Me If Windows XP/Windows Me is installed in your computer, and you perform the “System Restore” function of the Windows “System Tools,” the songs managed by OpenMG Jukebox may become corrupted and rendered unplayable. Therefore, before executing “S

43、ystem Restore,” back up the songs using “OpenMG Jukebox Backup Tool” first. Then, after the “System Restore” function is finished, restore the songs using “OpenMG Jukebox Backup Tool” to ensure the integrity and reliability of song playback. For more information about backup, refer to the online Hel

44、p for OpenMG Jukebox. Note When songs become unplayable by executing “System Restore,” an error dialog box may be displayed. In this case, follow the displayed messages. 6 MZ-S1 SECTION 2 GENERAL This section is extracted from instruction manual. 12-GB Looking at the controls Front of the recorder A
