Notice that the minus side of a tantalum capacitor may be dam-aged by heat.FLEXIBLE CIRCUIT BOARD REPAIRING Keep the temperature of 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.SAFETY CHECK-OUTAfter correcting the original service problem, perform the follow-ing safety check before releasing the set to the customer:Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage.Check leakage as described below.LEAKAGE TESTThe AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes.). Leakage current can be measured by any one of three methods.1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments.2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable.

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 fl ow) 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.NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNITThe laser diode in the optical pick-up block may suffer electrostat-ic 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 fl exible board is easily damaged and should be handled with care.NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused on the disc refl ective 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.NOTE OF REPLACING THE IC1103 ON THE MAIN BOARDIC1103 on the MAIN board cannot exchange with single. When this part is damaged, exchange the entire mounted board.MODEL IDENTIFICATION Rear View Part No.You can play the following types of discs on this player. Super Audio CDs Audio CDs DSD DiscsThis player cannot play the following discs. CD-ROMs (MP3, JPEG, etc.) DVDs DTS-CDs DualDiscs, etc.If you try to play CD-ROMs/DVDs, the error message “Cannot Play” or “No Disc” will appear. For DTS-CDs/DualDiscs, refer to their respective notes below.Music discs encoded with copyright protection technologiesThis product is designed to play back discs that conform to the Compact Disc (CD) standard.Recently, various music discs encoded with copyright protection technologies are marketed by some record companies. Please be aware that among those discs, there are some that do not conform to the CD standard and may not be playable by this product.Notes on CD-R/CD-RW playbackDiscs recorded on CD-R/CD-RW drives may not be played back because of scratches, dirt, recording condition, or the drives characteristics. Besides, the discs, which are not yet finalized at the end of recording, cannot be played back. In these cases, “Reading” will remain or “Cannot Play” will appear on the display.Note on DTS-CDsDTS signals are output from the DIGITAL OUT (CD) jacks only. The DTS signals must be decoded on a DTS-compliant digital device to be listened to. Note on DualDiscsA DualDisc is a two sided disc product which mates DVD recorded material on one side with digital audio material on the other side. However, since the audio material side does not conform to the Compact Disc (CD) standard, playback on this product is not guaranteed.Note on DSD DiscsA DSD Disc is a disc recorded in the DSF file format. This player can play DSF files that you have recorded on DVD-ROM compatible DVD-R, DVD-RW, DVD+R and DVD+RW discs. For details on DSD Discs.Compatib e Disc TypesSCD-XA5400ES5?
