CAUTION

Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.

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 viscou-s (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.

SERVICING NOTES

MZ-NH600D

Ver. 1.2

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

The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.

OPERATION CHECK WHEN THE LID IS OPEN

In making an operation check with the MAIN Board removed from the set, short the SL894 (OPEN/CLOSE) of the MAIN Board with the solder before starting the operation check.

Note: Be sure to remove the solder used for shortcircuit after the repaire

completed.

3-6. Setting The Adjustment Values 3-6-1. Hi-MD3 setting

Preparation:

1. Perform calculation every item based on the data given by the Hi-MD3 adjustment disc by referring to the following table. (Round off the value in decimal place)

2. Convert the calculated value into hexadecimal number.

Note: The Hi-MD3 adjustment parameters vary depending on the disc,

and therefore use the parameters of the disc used when performing the adjustment.

Item No. Calculating formula (*3)

(*2) Ppw / 0.05 0214 Kw × (−100) 0215 Prmin / 0.05 0216 Pwmin / 0.05

*1) If the “Pr_nominal” value is indicated, use the “Pr_nominal” value

and not used “Por” value.

*2) If the “Pw_nominal” value is indicated, use the “Pw_nominal” value

and not used “Ppw” value.

*3) Round off after the decimal point.

• Note For Printed Wiring Boards and Schematic Diagrams

Note on Printed Wiring Board:

• X : parts extracted from the component side.

• Y : parts extracted from the conductor side.

• : Pattern from the side which enables seeing.

(The other layers' patterns are not indicated.)

Caution: Pattern face side: Parts on the pattern face side seen from (Conductor Side) the pattern face are indicated. Parts face side: Parts on the parts face side seen from (Component Side) the parts face are indicated.

• Main board is multi-layer printed board. However, the patterns of intermediate-layer have not been included in this diagrams.

• Lead Layouts

Note on Schematic Diagram:

• All capacitors are in µF unless otherwise noted. (p: pF) 50 WV or less are not indicated except for electrolytics and tantalums.

• All resistors are in Ω and 1/ specified.

• f : internal component.

• C : panel designation.

Note:

The components identified by mark 0 or dotted line with mark 0 are critical for safety. Replace only with part number specified.

• A : B+ Line.

• Total current is measured with MD installed.

• Power voltage is dc 1.5 V and fed with regulated dc power

supply from battery terminal.

• Voltages and wa vef orms are dc with respect to ground in playback mode. no mark : PLAYBACK

• Voltages are taken with a V OM (Input impedance 10 MΩ). Voltage variations may be noted due to normal production tolerances.

• Waveforms are taken with a oscilloscope. Voltage variations may be noted due to normal production tolerances.

• Circled numbers refer to waveforms.

• Signal path.

E : PLAYBACK j : REC F : USB input from PC f : USB output to PC

• Abbreviation CND : Canadian model

W or less unless otherwise

Note:

Les composants identifiés par une marque 0 sont critiques pour la sécurité. Ne les remplacer que par une pièce portant le numéro spécifié.
