OPEN 1. Set SW70 to A (maximum gain), black stretch point 1 (18) to maximum (E0), subaddress (1C) data to (00)
2. Apply 0 V to #71 and connect external power supply PS to #68. Set PS to V
3. Determine intersection points (V
4. Set black stretch characteristic switch subaddress data (1C)/(1E) to (20)/(00) and (20)/(08) respectively. As
