D-FJ401/FJ405 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 dam- aged by heat.This Compact Disc player is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT label 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. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. DANGER Invisible laser radiation when open and interlock failed or defeated. Avoid direct exposure to beam. - Abbreviation D-FJ405 D-FJ401 Supplied accessories For the area code of the location in which you purchased the CD player, check the upper left side of the bar code on the package.

3 D-FJ401/FJ405 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 : IC601 yg pin (TP610) When checking FOK, remove the lead wire to disc motor. - RF signal P-to-P value : 0.4 to 0.5Vp-p SECTION 1 SERVICING NOTES 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 : 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.
