Adjust the VP (vertical) and the HP (horizontal) position using the 4, buttons. Press the Memory Initialize key of the R/C to store the value in memory. If you do not have this key, short the pins of the 2 pin connector PI1 for one second, then remove. Select PIP mode and shift the sub-picture using the SHIFT button. Distance between PIP and edge of screen should be equal when shifted. if it is not, repeat (i)-(5). Surround Operation Check Adjustment Preparation Input the following audio signals to the audio input of the VIDEO INPUT terminals. When checking surround: L CH: 400Hz sine wave 475mVrms R CH: 5kHz sine wave 475mVrms Set the INT. SPEAKER : ON Set the volume controls of FRONT and REAR to center. Set the BASS, TREBLE and BALANCE to center. Note: Front waveform: Front speaker output of the set. Rear waveform: Rear speaker output of the set. Surround Off Check Set to SURROUND: OFF and check shown below is obtained.
2.5.3 Matrix Surround Check Adjustment Preparation (1) Set to SURROUND : MATRIX Check that the following waveforms are obtained. Front : Check that the phases of R and L are different and 400H.z is superimposed on 5kHz. The amplitudes of R and L are different. Rear : Check that the phases of R and L are opposite and 400Hz is superimposed on SkHz. Front Rear
