CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
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.
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.
DANGER
Invisible laser radiation when open and interlock failed or defeated. Avoid direct exposure to beam.

SERVICING NOTES
NOTES ON HANDLING T HE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown 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 pick-up block.
Therefore, when checking the laser diode emission, observe from more than 30cm away from the objective lens.
Before Replacing the Optical pick-up Block
Please be sure to check thoroughly the parameters as per the “Optical pick-up Block Checking Procedure” (Part No. : 9-960-027-11) issued separately before replacing the optical Pick-up block.
Note and specifications required to check are given below.•FOK output : IC501 !™ pin
When checking FOK, remove the lead wire to disc motor.
•S curve P-to-P value : 0.9 – 1.5Vp-p IC501 #¡ pin. (Connect pin !™ of IC501 (TP880) and 3 of IC501 (GND) with a jumper wire).
When checking S curve P-to-P value, remove the lead wire to disc motor.
•Adjusted part for focus gain adjustment : RV503
•RF signal P-to-P value : 0.85 – 1.15Vp-p
•Traverse signal P-to-P value : 1.0 – 2.6Vp-p
•The repairing grating holder is impossible.
•Adjusted part for tracking gain adjustment : RV502

Precautions for Checking Emission of Laser Diode
Laser light of the equipment is focused by the object lens in the optical pick-up so that the light focuses on the reflection surface of the disc.
Therefore, be sure to keep your eyes more then 30cm apart from the object lens when you check the emission of laser diode.Laser Diode Checking Methods
During normal operation of the equipment, emission of the laser diode is prohibited unless the upper panel is closed while turning ON the S801 (push switch type).
The following two checking methods for the laser diode are operable.Method-1 (In the service mode or normal operation) :Emission of the laser diode is visually checked.1.Open the upper lid.
2.Push the S801 as shown in Fig. 1 .
3.Check the object lens for confirming normal emission of the
laser diode. If not emitting, there is a trouble in the automatic power control circuit or the optical pick-up. During normal operation, the laser diode is turned ON about 2.5 seconds for focus searching.
Fig.1 Method to push S801
Method-2 (In the service mode or normal operation) :Check the value of current flowing in the laser diode.1.Remove the upper panel.
2.Read the current printed on the rear side of the optical pick-up.
(Print on the rear side of the optical pick-up)
3.Connect a level meter as shown in Fig. 2
4.Press the ^ key.
5.Calculate the current value by the reading of the digital voltmeter
Reading of the tester (V) ÷ 4.7 ( Ω ) = current value (A)(Example) Reading of the digital voltmeter of 0.2256 V :0.2256 V ÷ 4.7 Ω = 0.048 (A) = 48 mA
6.Check that the current value is within the following range.•
Current value of the label      mA(25°C)Variation by temperature : 0.4mA / °C
Current increases with as temperature increases.Current decreases with as temperature decreases.
If the current is more than the range above, there is a trouble in the automatic power control circuit or the laser diode is in deterioration.If less than the range, a trouble exists in the automatic power control circuit or the optical pick-up.
