*1: In the absence of c.sync, Audio Mute goes "H".
*2: L1 / L2: Line1=L / L, Line2=L / H, Tuner=H / L
*3: "H" when the control speed is greater than LPx20, and "L" in other modes.
*4: "L" when the control speed is greater than LPx20, and "H" in other modes.
*5: "H" in ACC. Search (SPx7, EPx21). "L" in other modes.
*6: "H" when the control speed is greater than LPx5.
