Before installing the app, make sure that the door lock has been installed correctly, so please perform the following
test. If at any step you encounter problems, please refer to the Trouble Shooting section of this manual.
Note: Please keep the door open during the test, and make sure you did NOT unlock the lock.
1. Turn the front (outside) handle. The latch should NOT move (keeping locked status).
2. Turn the rear (inside) handle. The latch should retract, unlocking the door.
3. Wake up front panel (swipe finger across screen), then enter the default administrator password 123456 + # to
unlock. You should change the admin password later.
NOTE: If the Dato Home app has been installed and the lock has been added, the admin password may have
changed. Open the app and see the door lock setting interface to view the admin password.
NOTE: You can only set up one administrator for each lock.
4. Close the door and check if the latch properly inserts into the strike plate on the door frame.
