got exactly what i ordered in a very timely manner. will use again for other manuals
;
I'm happy. Good quality. Very helped me with my work..............................

This is the second Manual I have ordered from owner-manuals, I give it five stars because it is exactly what I expected given the age of the equipment. So the contents look a bit aged and the pictures a bit grainy, it fulfills my needs and I am glad I can still get hold of them.

thank u so much for this manual that was so cheap that i thought it was a scam but i gambled anyway because it was too good of a deal to pass up and behold,the manual has everything and details of everything even the screws and im still amazed and very happy with my manual .so take my word and jump on it before they realize how cheap they selling thier manuals..thank you so much for taking time to read my thoughts

I do not have very much to say.
The price is quite covenient, delivery was better as promised (about 12 ours, against the specified 24 hours if I remember well), and the quality of the PDF is more than acceptable.
The Service Manual of Sansui R30 itself is also satisfactory: good graphic for schematics and layouts, simple and well structured.

1.3.5 RF level auto-adjustment (RFAGC)
This adjustment minimizes the dispersion of the RF level (RFO), which may be caused by disc-related errors, for more stable signal transmission by changing the amp gain between RFI and RFO. <Adjusting procedures> 1) The external microcomputer sends the command to the servo LSI to read out the output from the RF level detecting circuit inside the servo LSI. 2) The external microcomputer calculates the appropriate amp gain by using the output read out to adjust the RFO level at the prescribed one. 3) The external microcomputer sends the command to the servo LSI to adjust the amp gain into the calculated one. This adjustment is automatically performed when: 1) During the setting-up mode, only the focus close operation ends. 2) Immediately before the setting-up ends (or right before the play mode starts) 3) During the play mode, the focus loop is locked again after unlocked.

1.3.6 Pre-amp gain adjustment
In this adjustment, when the reflected beams from disc surface are extremely weak (ex. when the lens is dirty, and a CD-RW is loaded), the whole gain in the RFAMP block (FE, TE, and RF amplifiers) is increased by +6dB or +12dB. <Adjusting procedures> When the system senses that the reflected beams from disc surface are extremely weak during the setting-up mode, the whole RFAMP gain is increased by +6dB or +12dB. After the gain is changed, the setting-up mode is restarted. If the whole RFAMP gain is always increased to the +6dB level in the play mode, the +6dB level will be employed at the starting of the setting-up mode from the next playback.

yy y ;;
Play is started with +6dB judging the lens is stained Play at +6dB increases due to stained lens or other reasons (the typical gain is employed for the initial setup) Time
