A complete and well done copy of the manual, at a not expansive price!
The delivery of the manual is very fast.
Thank you for all
;
Perfect quality. Was able to fix speed drifting on my Sansui Turntable using the service manual instructions for PLL adjustment.

I am very happy regarding the online purchase of this manual from Owner-Manuals.com as with this I could set right my Denon CD player and Amplifier.
I once again sincerely thank them for the prompt service which was rendered to me.

More than pleased with my prurchase, very good product for the price.

Manual-link came 30 minutes after having paid for an extremely rare (40 years old) item (sony icr-120) and helped me to get the radio rework again. So really good help for me, fast and reliable delivery and -taken that into consideration- a very reasonable price for that service. So thanks again! Mike, Germany

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.

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
