Thank´s for your help, I already recived these manual from you
;
Thank you for your manual It has the basic things to and i use the Oszi for Longer Time.

Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.

This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.

Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.
4. Connect an oscilloscope to the TP304 (IC301 Pin 36) blue * output.
CONTRAST ADJUSTMENT
5. Connect an oscilloscope (CHl) to the TP305 (IC301 pin 34) green output and (CH2) to the TP (IC301 pin 36) blue output. 6. Turn RV309 (SUB CONT B) to adjust the blue gain so that the positive polarity red signal step wave coincides with the positive polarity green signal step wave on the oscilloscope. 7. Disconnect pin 46 from pin 33 of IC301, and pin 45 from GND. The positive polarity signal and the negative polarity signal may not simultaneously coincide due to the variation.(Figures a and b) In this case, adjust these signals to an average value. (Figure c)
Procedure: 1. Short between IC301 pin-46 and pin-33, and between pin-45 and GND. (Short them at the same time.) Picture will show the white- compressed picture. 2. Input the 5- to 16-step black and white wave (stairstep) of the pattern generator (75 Sz and 1 Vp-p) to the A/V IN jack (J301). 3. Connect an oscilloscope (DC range 1 V/ DIV) to the TP305 (IC301 pin 34) green output. 4. Adjust RV307 (BRIGHT control) so that the black level obtains - 3.8V (line K).

5. Adjust RV301 (contrast) so that the white line obtains the GND potential (line M) (A = 3.8 t O.lVp-p). � 6. Disconnect pin 46 from pin 33 of IC301, and pin 45 from GND.
Note: These adjustments are not performed usually. Never
touch CT201 of adjusting device. While, only when CT201 have been replaced, make the following simple adjustment.

BALANCE
ADJUSTMENT
Note: When performing this adjustment, set the direct
current drift .adjustment so that the direct currents on each channel of the oscilloscope is stabilized, and use the oscilloscope in this condition. Procedure: 1. Short between IC301 pin-46 and pin-33, and between pin-45 and GND. (Short them at the same time.) Picture will show the white - compressed picture. 2. Input the 5- to 16-step black and white step wave (stair -step) of the pattern generator (75 Sz and 1 Vp-p) to the A/V IN jack (J301). 3. Connect an oscilloscope (CHl) to the TP305 (IC301 pin 34) green output and (CHZ) to the TP504 (IC301 pin 32) red output. 4. Turn RV308 (SUB CONT R) to adjust the red gain so that the positive polarity red signal step wave coincides with the positive polarity green signal step wave on the oscilloscope. -7-
Procedure: Input the monochromatic gradation .wave from EXT ANT IN jack (JlOl). Connect an oscilloscope to Q314 emitter. Adjust CT201 so that the synchro signal is maximum (VIF adjustment). Receive the broadcasts of 2 to 13ch, and check if the screen is colored after the synchronism is stopped with each channel.
