General Specifications - Frequency response : 20Hz~20KHz (Limeout) 100Hz~20KHz (H/pout) - Signal to noise ratio : 75dB(1KHz, Limeout) 65dB(1KHz, H/pout) - Distortion factor : 0.15% Less than(1KHz) - Channel separation : 65dB(1KHz, Limeout) 55dB(1KHz, H/pout) - Signal output level : LINEOUT : 0.7 Vrms(±20%) H/PHONE : 0.6 Vrms(±20%) - Used laser : Semiconductor laser - Drive type : Computer built-in - Power consumption : DC + 5V, 1.7A DC + 12V, 1.0A - Dimensions : 149mm(W)X41.5mm(H)X202.6mm(L) - Net Weight : 950g 2. Electrical Features - Interface : ATAPI BUS(IDE) - Data transfer rate 6000KByte/Sec MAX (3100KByte/Sec AVG.) - ACCESS TIME : 1/3 stroke : Below 120msec full stroke : Below 190msec - Buffer Capacity : 128Kbyte - Error ratio : Mode 1: Below 10-12 Mode 2: Below 10-9 Cautions at Service 1. General Items 2. Earthing cautions at handling Pick-up 1) Be careful not to have your eyes or a part of body touch with laser diode at repair because this product uses laser diode. 2) Do not disassemble Pick-up at repair. If the laser diode is bad, replace the entire Pick-up. 3) Keep away from TV or other electrical units at repair to prevent influence from surrounding units. 4) If you replace the parts during repair, be sure to unplug the power cable before replacement. 5) If you insert a disc into the drive, be sure to load it correctly. 6) Because this unit can't be used by itself, surely mount it on PC (486 DMA support) and check the operations in use of private device driver floppy diskette. Refer to Instruction manual. 7)This unit has many parts with features related to safety and especially, for essential parts, the importance is indicated on circuit diagram and part list. Be certain to use the parts with same specifications at replacing these parts. - Because the laser diode in optical Pick-up is subject to get out of order due to the potential difference occurring by electricity load charged in clothes or bodies, observe the following earthing items at handling. 1) Body earthing(hand) : Be sure to wear a wrist strip with one side earthed.(Impedance : Below 104). It removes the electricity formed in body. 2) Work table earthing : Put the earthed conductive plate(Impedance : Below 104) such as copper plate on work table. 3) Cautions for clothes : Do not have any clothes touch with Pick-up because the electricity formed in clothes is destroyed easily. 1 SCR-140(A4)-e n 99.3.1 5 8:3 6 AM Æ Á 3 Disassembly Method 1.
