Very good scanning quality. All schematics are very legible. Worth every cent !
;
Excellent quality, very quick download turnaround, will definately use again.

This is a awesome quality scan of the original Service Manual for Technics 8099.
Contains the circuit diagram, PCB layout, adjust/tune instructions as well.
Since this is my first buy here, i'm really glad! This site do works as intended/described, it's definitely not scam!
Мои рекомендации! Все мануалы настоящие!

Good Quality of the File.
You get the normal manual is incudet.

Very nice and real Service Manual, I didn't thought it actually exist in the real world at all.

LSI(IZA968DR) The I/O signal of the LSI(IZA968DR) is detailed in the following table. Pin No. 1-2 3-6 Signal VL2-VL1 AN7-AN4 I/O IN IN Description Power source voltage input terminal. Standard voltage for LCD. Terminal to change cooking input according to the Model. By using the A/D converter contained in the LSI, DC voltage in accordance with the Model in operation is applied to set up its cooking constant. Terminal not used. Signal coming from touch key. When either G13 line on key matrix is touched, a corresponding signal out of P20 - P27 will be input into AN2. When no key is touched, the signal is held at "H" level. To input signal which communicates the door open/close information to LSI. Door close "H" level signal (0V). Door open "L" level signal (-5V). Input terminal to judge the model. The one of signals P20-P27 will be input into AN0 through one of G1-G8 lines on key matrix. The LSI will judge the model by this signal. Terminal not used. Signal to sound buzzer (2.0 kHz). 0.12 sec. H : GND A: key touch sound. A B: Completion sound. L : -5V 2.4 sec.
H : GND B L : -5V

Magnetron high-voltage circuit driving signal. To turn on and off the cook relay (RY2). The signals holds "L" level during microwave cooking and "H" level while not cooking. In other cooking modes (variable cooking) the signal turns to "H" level and "L" level in repetition according to the power level.

When either G12 line on key matrix is touched, a corresponding signal will be input into P45. Signal similar to AN2. When either G11 line on key matrix is touched, a corresponding signal will be input into P44. Signal similar to AN2. When either G10 line on key matrix is touched, a corresponding signal will be input into P43. Signal synchronized with commercial power source frequency. This is the basic timing for time processing of LSI. H : GND

Signal similar to AN2. When either G9 line on key matrix is touched, a corresponding signal will be input into P41. Connected to GND through the pull-down resistor R90. Auto clear terminal. Signal is input to reset the LSI to the initial state when power is applied. Temporarily set "L" level the moment power is applied, at this time the LSI is reset. Thereafter set at "H" level. Terminal not used.
