How do I change the preset Sensor Cycles Dryness setting if my clothes are consistently not dry enough?

Press and hold the Sensor Cycles Dryness button for 5 seconds while the dryer is not running; the dryer will beep and display 'CF' followed by the current dryness setting. Press the Sensor Cycles Dryness button again to cycle through the three settings: 1 (factory preset), 2 (approximately 15% more drying time), or 3 (approximately 30% more drying time). Press START/PAUSE to save the new setting, which will then apply to all Sensor cycles. (Page 23)
