Polarity of the plug
· Connect the AC power adaptor to an easily accessible AC outlet. Should you notice an abnormality in the AC power adaptor, disconnect it from the AC outlet immediately. · The recorder is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the recorder itself has been turned off. · If you are not going to use this recorder for a long time, be sure to disconnect the power supply (AC power adaptor, dry battery, rechargeable battery, or car battery cord). To remove the AC power adaptor from the wall outlet, grasp the adaptor plug itself; never pull the cord.

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-N510CK 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 (LCX-5R) 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. · 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.

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 discriminated 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.
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.

3. During each test, the optical pick-up moves outward or inward while the > or . key is pressed for several seconds respectively. 4. Each test item is assigned with a 3-digit item number; 100th place is a major item, 10th place is a medium item, and unit place is a minor item. The values adjusted in the test mode are written to the nonvolatile memory (for the items where adjustment was made).

5. The display changes a shown below each time the [END SEARCH] key is pressed.
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 1. Set the test mode (see page 13). 2. In the display check mode, press the [GROUP] key activates the self-diagnosis result display mode where the LCD display as shown below.

Rewriting the Patch Data at Replacement of Main Board
This set requires the patch data in the nonvolatile memory (IC852) to be rewritten using the application, when the MAIN board was replaced. Caution: The application that meets the microcomputer version in this set must be used when rewriting the patch data. Rewriting the patch data using the application not suitable for the microcomputer version could cause the set to malfunction. For a checking method of the microcomputer version, see "SECTION 4 TEST MODE" (page 13). · Preparation 1. USB cable (attached to the set) 2. Personal computer in which the Net MD Driver has been installed. (For further information, see "System requirements" (page 4) in "SECTION 1 SERVICING NOTES") 3. Application "USB_PatchWriter" for patch data rewriting · How to Get the Application "USB_PatchWriter" for Patch Data Rewriting Contact our service technical support division to get the application. · Pre-check 1. Check the microcomputer version in this set. (For a checking method of the microcomputer version, see "SECTION 4 TEST MODE" (page 13).) 2. Check that the Net MD Driver has been installed in the personal computer. 3. Make sure that the set is in the Normal mode.
Note: Do not rewrite the patch data in the Test mode.
· Rewriting the Patch Data 1. Connect the set to the personal computer with the USB cable. 2. Start the application "USB_PatchWriter". 3. Make sure that the following window opens. 4. Click the [USB CONNECT] button.
31

5. Confirm that the model and version indicated on the title bar coincide with the codes displayed in the Device Name block and the Version block in the window.
6. Click the [Write + Read] button. The patch data writing and the verify processing will be executed automatically in the following order: 1) Writing to patch area (front area) 2) Writing to patch area (reverse area) 3) Verifying patch area (front area) 4) Verifying patch area (reverse area) 7. The operation will terminate with the a (blue) mark given to all areas. If the × (red) mark is given to any area, the nonvolatile memory will be faulty.

· Disconnecting the USB cable Disconnect the USB cable as the following procedure after rewriting the patch data and confirmation.
Note : When the following procedure is not completed but USB cable is extracted, the application does not recognize the set at exchanging of the set.
1. Click the [USB DISCONNECT] button.
2. Confirm that "You can change another device" is displayed in the message block.
3. Disconnect the USB cable from the personal computer and the set.
