Installation:Close the door or window; peel off the cover of the enclosed adhesive tape on the unit and the controller. Attach the main unit and the controller onto the door and door frame respectively. Make sure the base of the main unit and the controller are lined up horizontally. The distance between the two devices must be less than 6mm.

How to Use:* Flip the on/off switch to “ALARM” position. If an intruder opens the door/window, it will give out a sharp warning signal to warn the intruder to leave. * Flip the switch on the left of the unit to “CHIME” position. When someone opens the door to which the unit is attached, it will play the “ding dong” melody to signal the entrance of the visitor. * Flip the switch to the “off” position to turn off the unit.
