Design and specifications are subject to change
without notice.
This appliance is
classified as a CLASS 1
LASER product. This
label is located on the
rear exterior.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
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.
FOR CD
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 pick-
up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
FOR MD
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.
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.
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.)
The following caution label is located inside the apparatus.

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.

Iop DATA RECORDING AND DISPLAY WHEN OPTICAL PICK-UP AND NON-VOLATILE MEMORY (IC195 OF
BD BOARD) ARE REPLACED
The Iop value labeled on the optical pick-up can be stored in the non-volatile memory. By storing the value, it will eliminate the need to look
at the value on the label of the optical pick-up. When replacing the optical pick-up or non-volatile memory (IC195 of BD (MD) board), store
the Iop value on the optical pick-up according to the following procedure.
Record Precedure:
1. Press the ?/1button to turn on the power.
2. Press the FUNCTION button to select the “MD” function.
3. While pressing the xbutton and the ENTER/START button at the same time, press the FUNCTION button.

5. Press the >“R” button to display “Iop Write” (C05) and press the ENTER/YES “R” button.
6. The display becomes “Ref=@@@.@” (@ is an arbitrary number) and the numbers which can be changed will blink.
7. Input the Iop value written on the optical pick-up.
To select the number : Press the .“R” button or the >“R” button.
To select the digit : Press the REC MODE button.
8. When the ENTER/YES “R” button is pressed, the display becomes “Measu=@@@.@” (@ is an arbitrary number).
9. As the adjustment results are stored for the 6 value. Leave it as it is and press the ENTER/YES “R” button.
10. “Complete!” will be displayed momentarily. The value will be stored in the non-volatile memory and the display will become “Iop
Write” (C05).
11. Press the REPEAT “R” button to exit the mode.
12. Press the ?/1button to turn off the power.
Display Precedure:
1. Press the ?/1 button to turn on the power.
2. Press the FUNCTION button to select the “MD” function.
3. While pressing the xbutton and the ENTER/START button at the same time, press the FUNCTION button.
4. Press the >“R” button to display “[Service]”. Then press the ENTER/YES “R” button.
5. Press the >“R” button to display “Iop Read” (C26) and press the ENTER/YES “R” button.

8. Press the ?/1 button to turn off the power.
Checks Prior to Parts Replacement and Adjustments in MD
Before performing repairs, perform the following checks to determine the faulty locations up to a certain extent.
Details of the procedures are described in “Section 5 Electrical Adjustments”.
Note:
The criteria for determination above is intended merely to determine if satisfactory or not, and does not serve as the specified value for adjustments.
When performing adjustments, use the specified values for adjustments.
