On power sources

Use house current, Nickel Cadmium rechargeable battery, LR6 (size AA) battery, or car battery. For use in your house: Use the AC power adaptor supplied with this recorder. Do not use any other AC power adaptor since it may cause the recorder to malfunction.

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.

MANUAL MODE

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. Transition Method in Manual Mode 1. Set the test mode (see page 13). 2. Press the > or[VOL +] key activates the manual mode where the LCD display as shown below.

changed: Adjusted value is written. When adjusted value is not changed: That item is adjusted automatically.

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 [MENU/ENTER] key.

OVERALL ADJUSTMENT MODE

Mode to adjust the servo automatically in all items. Normally, automatic adjustment is executed in this mode at the repair. For further information, refer to SECTION 5 ELECTRICAL ADJUSTMENTS (see page 19).

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 pickup 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 pickup was replaced. Self-Diagnosis Result Display Mode Setting Method 1. Set the test mode (see page 13). 2. In the display check mode, [MENU/ENTER] key activates the self-diagnosis result display mode where the LCD display as shown below.

MZ-N505 SECTION 5 ELECTRICAL ADJUSTMENTS
In this set, automatic adjustment of CD and MO can be performed by entering the test mode. However, before starting automatic adjustment, the memory clear, power supply adjustment, and laser power check must be performed in the manual mode. A key having no particular description in the text, indicates a set key.

NV RESET

Caution: 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. Change the NV adjustment values according to the microcomputer version. Setting Method of NV Reset 1. Select the manual mode of the test mode, and set item number 021 (see page 14).
PRECAUTIONS FOR ADJUSTMENT

Trouble-free operation is not assured within a multiple-monitor environment. We do not assure trouble-free operation for all computers satisfying the system requirements. Trouble-free operation is not guaranteed following the self-conducted upgrade of home-built PCs or operating systems. We do not assure trouble-free operation of the system suspend, sleep, or hibernation function on all computers. For details, refer to Net MD Help of the online help.
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.
