Notes on chip component replacement · Never reuse a disconnected chip component. · Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing · Keep the temperature of the soldering iron around 270 °C during 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 soldering or unsoldering. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree 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 solder 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 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. · Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

MZ-N10 SECTION 1 SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged 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 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 (ABX-1R) The laser diode in the optical pick-up block may suffer electrostatic break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform measures against electrostatic break-down sufficiently before the operation. The flexible board is easily damaged and should be handled with care. · Replacement of SN761058ZQL (IC501), CDX2678-202GA (IC801) used in this set requires a special tool · The shipment data will be cleared when the NV is reset. Therefore, change the NV adjusted values following the Change of NV Adjusted Values immediately after the NV was reset. (See page 17) · This set requires the patch data in the nonvolatile memory (IC851) to be rewritten using the application, when the MAIN board was replaced. (See page 28)

System requirements
The following hardware and software are required in order to use the SonicStage software for the Net MD. Computer IBM PC/AT or Compatible · CPU: Pentium II 400 MHz or higher (Pentium III 450 MHz or higher is recommended.) · Hard disk drive space1): 120 MB or more · RAM: 64 MB or higher (128 MB or higher is recommended) Others · CD-ROM drive (capable of digital playback by WDM) · Sound Board · USB port (supports USB 2.0 Full Speed (previously USB 1.1)) Operating Factory installed: System Windows XP Home Edition/Windows XP Professional/ Windows Millennium Edition/Windows 2000 Professional/ Windows 98 Second Edition Display High Color (16bit) or greater, 800 × 480 dots or more (800 × 600 dots or more is recommended) Others · Internet access: for Web registration and EMD services · Windows Media Player (version 7.0 or higher) installed for playing WMA files

laser-tap OPTICAL PICK-UP FLEXIBLE BOARD

Note on hard disk drive space
120 MB or more free space on the hard disk drive is required. If your computer does not have enough space, the software will not be properly installed. The required free space differs according to the version of your Windows OS, or the amount of audio files that you handle.

· In performing the repair with the power supplied to the set, removing the MAIN board causes the set to be disabled. In such a case, fix a convex part of the open/close detect switch (S803 on MAIN board) with a tape in advance. · Handle the FLEXIBLE board (over write head) with care, as it has been soldered directly to the MAIN board. In repairing the component side of MAIN board, connect the FLEXIBLE board (over write head) and the MAIN board with the lead wires in advance.

This software is not supported by the following environments:
· Macintosh · Windows XP versions other than Home Edition or Professional · Windows 2000 versions other than Professional · Windows 98 versions other than Second Edition · Windows NT · Windows 95 · Personally constructed PCs or operating systems · An environment that is an upgrade of the original manufacturer-installed operating system · Multi-boot environment · Multi-monitor environment

MZ-N10 SECTION 4 TEST MODE
Outline
· This set provides the Overall adjustment mode that allows CD and MO discs to be automatically adjusted when in the test mode. In this overall adjustment mode, the disc is discriminate between CD and MO, and each adjustment is automatically executed in order. If a fault is found, the system displays its location. Also, the manual mode allows each individual adjustment to be automatically adjusted. · Operation in the test mode is performed with the set. A key having no particular description in the text, indicates a set key. · For the LCD display, the LCD on the remote commander is shown, but the contents of LCD display on the set are same. (Both displays may be displayed.) 3 In case of setting the test mode by keys on the set and remote commander: In the normal mode, turn on the [HOLD] switch on the set. While pressing the x key on the set, press the keys on the remote commander with the following order: > t > t . t . t > t . t > t . t t
Note: If electrical adjustment (CD and MO overall adjustment) has not been finished completely, "ERROR" is displayed on LCDs of the set and the remote commander.

Operation in Setting the Test Mode
· When the test mode becomes active, first the display check mode is selected. · Other mode can be selected from the display check mode. · When the test mode is set, the LCD repeats the following display.

Setting Method of Test Mode

· When the X key is pressed and hold down, the display at that time is held so that display can be checked.

Releasing the Test Mode
For test mode set with the method 1: Turn off the power and open the solder bridge on SL803 (TEST) on the MAIN board.
Note: Remove the solders completely. Remaining could be shorted with the chassis, etc.

For test mode set with the method 2 or 3: Turn off the power.

Mode to adjust or check the operation of the set by function. Normally, the adjustment in this mode is not executed. However, the Manual mode is used to clear the memory, power supply adjustment, and laser power check before performing automatic adjustments in the Overall Adjustment mode. The manual mode consists of a major item, a medium item and a minor item. The manual mode is divided into four groups of major items. SERVO : item number 000 - 500, 800 AUDIO : item number 600 POWER : item number 700 OP : item number 900 A medium item divides a major item and is used to select functions.

Self-Diagnosis Result Display Mode
This set uses the self-diagnostic function system in which if an error occurred during the recording or playing, the mechanism control block and the power supply control block in the microcomputer detect it and record its cause as history in the nonvolatile memory. By checking this history in the test mode, you can analyze a fault and determine its location. Total recording time is recorded as a guideline of how long the optical pick-up has been used, and by comparing it with the total recording time at the time when an error occurred in the selfdiagnosis result display mode, you can determine when the error occurred. Clear both self-diagnosis history data and total recording time, if the optical pick-up was replaced. · Self-diagnosis result display mode setting method
