Range and tilt angle

Range (m)	±2-10°	±4-14°	±6-20°	±10-26°
50, 85, 100, 150, 200, 250, 300, 350	±10°	±14°	±20°	±26°
400, 450, 500	±8°	±12°	±16°	±20°
600, 800	±6°	±10°	±14°	±20°
1000, 1200, 1600	±2°	±4°	±6°	±10°

For example, when the [RANGE] control, [TILT] lever and automatic tilt are set to 1000 m, 8° and ±2-10° respectively, the tilt angle changes at each transmission as follows:

8° → 10° → 8° → 6° → 8° → ...
