The manual adjustments in which jitter measurement is not performed, can be executed using this display. When any desired item number is selected, present setting of the item is shown. The adjustment value can be increased or decreased using the arrow mark keys (����). The adjustment value is stored in EEPROM. 0. TRK. Offset The tracking offset adjustment is performed. When adjusting a DVD, the tracking offset is canceled coarsely by SSI33P3720A with the peak bottom that is measured by DSP. The fine tracking offset adjustment is performed within the DSP. This adjustment sets the value for the fine adjustment. Because this is the adjustment within the DSP only, the DC component of the tracking traverse is not chaned. When adjusting CD, this setting value only is changed. The tracking offset adjustment of DVD is performed. (For SSI) Adjustment range: Lower 4 bits = 7 to 1, 8 to F ( +175 to +25mV, 0 to -175mV) The simple AGC adjustment of CD is performed. Adjustment range:Higher 4 bits = x000 to x101(binary) Focus gain is adjusted. Tracking gain is adjusted. When tracking gain in CD mode is adjusted, the simple AGC is set in which 5 different steps of -3.2, -1.6, 0, +1.6, +3.2 dB can be set in CXA2555Q based on the peak bottom that is measured by DSP. (Auto Tracking Offset) Then the setting inside DSP is performed. (Auto Tracking Gain) The setting inside DSP can be performed by this adjustment. When tracking gain in DVD mode is adjusted, only the setting inside DSP can be performed.
