IMPORTANT THIS PIONEER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRCUTED PERSON. LASER DIODE CHARACTERISTICS MAXIMUM OUTPUT POWER: 5 mw WAVELENGTH: 708-785 nm ZYXJ type Only ZYXJ type Only ZVXJ type Only (Right side view) LABEL CHECK 1. Laser Interlock Mechanism The loading position detect switch (in CD mechanism assembly) is set to "CLMP ON(CD CLOSE)" (ON:low level,OFF:high level) position, the system control IC(IC5501) get the "CLMP" signal, and hand the laser "LDON" signal to IC1101. Then a laser diode can be lighted except when the level of signal CLMP is low. The interlock also does not function in the test mode∗. Laser diode oscillation will continue, if pin 1 of CXA1821M (IC1101) on the CDMAIN UNIT is connected to GND, or pin 19 is connected to low level (ON), or else the terminals of Q1101 are shorted to each other (fault condition). 2. When the cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 1 laser beam. ∗ : Refer to page 54.

PCB PARTS LIST NOTES: •Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List. •The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. •When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%). 560 Ω → 56 × 10 1 → 561 ........................................................ RD1/4PU 5 6 1 J 47k Ω → 47 × 10 3 → 473 ........................................................ RD1/4PU 4 7 3 J 0.5 Ω → R50 ..................................................................................... RN2H R 5 0 K 1 Ω → 1R0 ..................................................................................... RS1P 1 R 0 K Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k Ω → 562 × 10 1 → 5621 ......................................................

(Refer to Fig. 6–3). (2) Clean the heads and demagnetize them using a head eraser. (3) Set the measurement level to 0 dBV = 1 Vrms. (4) Use the specified tape for adjustment. Use the labeled (A) side of the test tape. NCT–111 : For Tape Speed adjustment STD-331E : For Playback adjustment STD–632 : Normal blank tape * As the reference recording level is 250 nwb/m for STD– 331E, the recording level will be higher by 4 dB for STD– 331B (160nwb/m). When adjusting, pay carefull attention to the type of tape used. (5) Provide yourself with the following measuring devides: ÷ AC millivoltmeter ÷ Low-frequency oscillator ÷ Attenuator ÷ Oscilloscope (6) Adjust both right and left channels unless otherwise specified. (7) Turn the DOLBY NR switch off unless otherwize specified. (8) Warm up the unit for several minutes before adjustment. In particular, be sure to warm up the unit in the REC/PLAY mode for 3 to 5 minutes before starting recording/playback frequency characteristics adjustment. (9) Always follow the indicated adjustment order. Otherwise, a complete adjustment may not be achieved. 7� List of Adjustments ¶ Playback Section (1) Tape Speed Confirmation (2) Head Azimuth Adjustment (3) Playback Level Adjustment ¶ Recording Section (1) Recording Bias Adjustment (2) Recording Level Adjustment Dolby noise reduction manufactured under license from Dolby Laboratories Licensing Corporation. “DOLBY” and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation.

(High:sync protection window released) • XUGF is the negative pulse for the frame sync derived from the EFM signal. It is the signal before sync protection. • XPLCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge of XPLCK and the EFM signal transition point coincide. • GFS goes high when the frame sync and the insertion protection timing match. • RFCK is derived with the crystal accuracy. This signal has a cycle of 136µs. • C2PO represents the data error status. • XRAOF is generated when the 16K RAM exceeds the ±4F jitter margin. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 60 XC-IS21T •Pin Function PDG242B (U-COM ASSY : IC5501) • System Control IC No. Name I/O Description 1 TCRECF I Mecha RECF SW 2 TCTIN O TAPE Tray load in 3 TCTOUT O TAPE Tray load out 4 LCD POWER O LCD ON/OFF 5 LIGHT O LCD Buck light control 6 CDDSW1 I CD Door detection Input 1 7 CDDSW2 I CD Door detection Input 2 8 STBYLED O Standby LED control 9 CDDSW3 I CD Door detection Input 3 10 CDDSW4 I CD Door detection Input 4 11 CDCOLSE O CD Door close drive output 12 CDOPEN O CD Door open drive output 13 CD LDON I CD laser diode control output 14 CDINSID I CD inside SW input 15 CDSCLK O CD automatick adjustment input clok 16 CDSENS I CD LSI replay (GFS, FOK) 17 CDCLK O CD LSI clock 18 CDLAT O CD LSI latch 19 CDDATA O CD LSI data 20 CDSYSM O CD decoder mute control 21 CDRESET O CD LSI reset 22 CDCONT O CD LSI power control 23 CDMUTE O CD mute control 24 LINE2 MUTE O Line2 mute control 25 LINE1 MUTE O Line1 mute control 26 LINE CONT O Line ATT control 27 VOLCE O E-Volume LSI chip enabled 28 VOLDATA O E-Volume LSI data 29 SCLK O System bus clock 30 RST - Reset 31 EXTAL - Oscillator pulses 32 XTAL - ( 12MHz) 33 Vss - GNDD 34 VOLCLK O E-Volume LSI clock 35 SYSPOW O System power control 36 AVSS - GNDD 37 AVREF - +5V 38 KEY1 O Key input 39 KEY2 O Key input 40 KEY3 O Key input No. Name I/O Description 41 PROTECT O Protect detection input 42 SIMUKE O Model type select input 43 ST/TUNE O TX STREO/TUNED input 44 JOGIN O Multi JOG input 45 - - - 46 SDATA I/O Systembus data 47 SREQ I/O Systembus reqest 48 LCDCLK O LCD micro computer clock 49 LCDCE O LCD micro computer CE 50 LCDDAT O LCD micro computer data 51 CDSQCK O CD SUBQ clock 52 CDSQSO I CD SUBQ data input 53 LCDRST O LCD micro computer reset control 54 TOUCH I Touch sencer input 55 MS I MS Signal input 56 - - - 57 RDSDATA I RDS data input 58 PDSPOW O RDS power control 59 BEEP O beep control 60 ACPULS I AC puls input 61 REMIN I Remote control input 62 CDSCOR I CD SUBQ level input 63 RDSSCLK I RDS clock input 64 TXPOW O TX poer control 65 TXCE O TX LSI chip enabled 66 TXODAT O TX LSI data output 67 TXCLK O TX LSI clock 68 TXIDAT I TX LSI data input 69 TXMUTE O TX mute control 70 SPCONT O Speaker relay control 71 SYSMUTE O System mute control 72 VDD - +5.0V 73 NC - - 74 TCSENS I Reel pulse 75 EXPCE O EXPIC for CE control 76 TCOPEN O Tray open SW 77 TCCLOSE O Tray close SW 78 TCHALF I Mechanism HALF SW 79 TCMODE I Mechanism mode SW 80 TCRECR I Mechanism RECR SW www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 61 XC-IS21T Front Panel Assy 1 1 1 1 1 5 2 3 4 9 4 1 ×2 ×2 1 ×2 ×2 ×2 ×2 Rear Cover Note : Flexible cables are not removed in the case of the adjustment, but remove the Flexible cables to apply in the case of the exchange or repair.
