There are two ways to calibrate the lock.
1. Auto calibration - Turn the Danalock manually until the door is unlocked and leave the door open while calibrating. Lift the handle if needed. Now click 3 times, after 5 seconds the Danalock will calibrate.
2. Manual calibration (start by turn to unlock). Turn the Danalock completely into the unlock position, then click twice. Wait 5 seconds until it flashes yellow, then turn the Danalock into locked position and click once.
