How do I adjust the preset dryness level settings on my Maytag dryer?

Press and hold the DRYNESS button for 5 seconds until the dryer beeps and 'CF' is displayed, followed by the current drying setting. Press DRYNESS again to cycle through three settings: 1 (factory preset), 2 (approximately 15% more drying time), or 3 (approximately 30% more drying time), then press START to save. This change will affect all Sensor Dry cycles. (Page 25)
