Flexible Circuit Board Repairing ·Keep the temperature of the soldering iron around 270ûC 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 dam- aged by heat. NOTES ON HANDLING THE 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 30 cm away from the objective lens. ATTENTION AU COMPOSANT AYANT RAPPORT Ë LA SƒCURITƒ!!
