For drawers and hinged doors with push-to-open function, the locking component must also be installed. If the battery voltage is too low, the lock no longer locks and a 15 second continuous tone is emitted. In order to avoid interference between locks, a minimum distance of 10 cm (3 15/16”) must be maintained between installed locks and also during storage. If the distance is less than this minimum, continuous communication will take place between the locks, which will drain the battery. To avoid unnecessary battery draining, do not insert the battery until start-up.
