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
TEL
repair parts.
The flexible board is easily damaged and should be handled with
care.
FOR DVD
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.
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.
Laser component in this product is capable
of emitting radiation exceeding the limit for
Class 1.
13942296513
This appliance is classified as a CLASS 1 LASER product. The
CLASS 1 LASER PRODUCT MARKING is located on the rear

exterior.
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.

Iop DATA RECORDING AND DISPLAY WHEN OPTICAL PICK-UP AND NON-VOLATILE MEMORY (IC195 OF
BD BOARD) ARE REPLACED
Q
Q
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 board), store the Iop
value on the optical pick-up according to the following procedure.
Record 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 x button and the REC MODE button at the same time, press the FUNCTION button.
4. Press the MD > “R” button to display “[Service]”. Then press the ENTER/YES “R” button.
5. Press the MD > “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.
TEL 13942296513 QQ 376315150 892498299
To select the number : Press the MD . “R” button or the MD > “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 button twice to exit the mode.
12. Press the ?/1 button to turn off the power.
