- Finish the reset process.
Changing Anti-Collision Sensitivity
- Press the DOWN button until the base reaches its lowest position.
- Press and hold the DOWN button again until the LED reads "RST".
- Press and hold the UP button (about 5 seconds) while the LED flashes "RST" then switches to:
- 10.5 = 22 lbs. (10 kg) pressure (most sensitive)
- 10.6 = 33 lbs. (15 kg) pressure (middle sensitive)
- 10.7 = 44 lbs. (20 kg) pressure (least sensitive)
