Each time one disc was adjusted, it is ejected. Replace it with the specified disc following the message. Y ou can finish the adjustment by pressing the RETURN O “R” button on the remote com- mander.

Note: During adjustment of each disc, the measurement for disc type

judgment is made. As automatic adjustment does not judge the disc type unlike conventional models, take care not to insert wr ong type discs. Also, do not give a shock during adjustment.

AUTO SERVO ADJUSTMENT

After parts related to the servo circuit (RF amplifier (IC001), DSP (IC509), motor driver (IC501), EEPROM (IC903) so on) are replaced, re-adjusting the servo circuit is necessary. Select “ALL” at “1. DRIVE AUTO ADJUSTMENT” (Refer to page 4 in TEST MODE) and adjust DVD-SL (single layer), CD and D VD-DL (dual layer).

[TEST DISC LIST]

Use the following test disc on test mode. TDV-520CSO (DVD-SL): PART No. J-2501-236-A LUV-P01 (CD): PART No. 4-999-032-01 TDV-540C (DVD-DL): PART No. J-2501-235-A

Note: Do not use exiting test disc for DVD.

HCD-BC150/BC250

Procedure:

1. Connect an oscilloscope to CN901 pin 1 (RF) and CN901 pin 3 (GND) on the SUB board.

2. Turn the power on.

3. Set the test disc (DVD: TDV-520CSO, CD: LUV-P01) on the tray and press H button to playback.

4. Confirm that oscilloscope waveform is clear and check RFMON signal level is correct or not.

Note: A clear RFMON signal waveform means that the shape “◊” can be

clearly distinguished at the center of the waveform.
