Thanks for this "hard to find" service manual.
I apreciate the good quality of scanning and the pages scanned in A3 format.

Helpd me mont a new carradio when prewius mont was a mess.
;
Very good service and quick service, very good quality of service manual!
;
Great tape deck manual!
I'm very positively surprised, because it is a very long manual, lot of pages, drawings, diagrams, description of how to make the alignment and adjustment procedures.
It is as good as the old "Naka" manuals from the 1970's - if somebody have seen them, they know what I mean by that.
I recommend to buy this very much !

I am a vintage hifi collector. No way to fix that device without the appropriate service manual...thanks to your site I got it and every thing is easier now. I got the manual right after ordering: fast cheap accurate ... thank you

MECHANISM COMPATIBILITY ADJUSTMENT
4.3.1 Tape pattern adjustment
JIG CONNECTOR CABLE (YTU93106C)
MAIN CN113 EXMOD_1 1 SYS_TMS 21 SYS_TCK 2 SYS_TDI 22 SYS_TRSTL 3 SYS_TDO 23 SYS_RSTL AL_3VSYS IF_TX JLIP_TX JLIP_RX TXD2 RXD2 NC 4 24 5 25 6 7 26 27 6 7 8 9 JLIP_RX RXD2 I_MTR NC
NOTE: Prior to the adjustment, remove the COVER (ADJ). (1) Play back the compatibility adjustment tape. (2) While triggering the HID, observe the waveform of ENV_OUT. (3) Set the manual tracking mode (ATF OFF). (4) Confirm that the waveform is entirely parallel and straight, and free from remarkable level-down, through the tracking operation. Make the confirmation as follows if necessary. (5) If level-down is observed on the left hand side of the waveform, straighten the level by turning the GUIDE ROLLER (SUP). If level-down is observed on the right hand side of the waveform, straighten the level by turning the GUIDE ROLLER (TU). For actual adjustment, first, turn both the GUIDE ROLLERS (SUP and TU) to tightening direction (clockwise) in order to misalign the waveform once. Next, turn the GUIDE ROLLERS to returning direction (counterclockwise), then stop turning at the point where the waveform becomes flat. Turn only the GUIDE ROLLER (SUP) further more, then stop turning at the point where the waveform starts changing. (6) After the adjustment, try the unloading motion once, and confirm that the waveform is flat when the tape has been played back again. (7) Play back the self-recording. (8) Confirm that the waveform is flat.
NOTE:
The JIG connector board uses 30 pins from among 40 pins of CN113 on the MAIN board. Pins 1 to 5, 21 to 24 and 34 of CN113 on the MAIN board are not used

Electrical adjustment is performed by using a personal computer and software for SERVICE SUPPORT SYSTEM. Read README.TXT file to use the software properly. As for the connection of cables, see "4.2 JIG CONNECTOR CABLE CONNECTION". (No.YF093)1-19
