Procedure:
1. Connect an oscilloscope to RF pin and GND pin on the special
jig (J-2501-272-A).
2. Turn the power on.
3. Set the test disc (DVD: TDV-520CSO, CD: LUV-P01) on the

tray and touch the u 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 “
◊
