This service manual helped me to repair my PIONEER. Iam very satisfied, that I found it here. Even the price of manual was not so high that person would not be able to spend a few money. But that is very worth spent money. Thanks

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.

B

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.
