Model: DS17 (1 AC Receiver, 3 Battery-Powered Magnet Sensors)
The CallToU DS17 Wireless Door Sensor Chime is designed to provide notification when a door or window is opened. It functions as a door chime, an anti-theft alarm, or a visitor notification system for various environments such as homes, offices, stores, and garages. The system features adjustable volume, multiple melody options, and a long communication range.
Please ensure all the following items are present in your package:

Plug the AC-powered receiver unit into a standard wall power outlet. The receiver will power on and be ready for operation.
Attach the magnet sensor to your desired door or window frame using the provided double-sided adhesive tape. Ensure the two parts of the sensor (main unit and magnet) are aligned and within 1.5 cm (0.6 inches) of each other when the door/window is closed. The sensor can be installed on various surfaces like doors, windows, and drawers.

Press the volume button on the receiver to cycle through 5 different volume levels, ranging from silent (0dB) to maximum (110dB). This allows you to adjust the sound output based on your environment and preference.
Use the up and down arrow buttons on the receiver to browse and select from 55 different melodies. Once a melody is selected, it will be saved for future alerts.
When the magnet sensor detects an opening (i.e., the main unit and the magnet part separate by more than 1.5 cm), it will wirelessly transmit a signal to the paired receiver. The receiver will then activate the selected chime and flash its LED indicator.

The magnet sensor is powered by a 12V 23A battery. When the battery is low, the sensor's indicator light may not flash, or the signal range may decrease. To replace the battery, carefully slide open the sensor casing, remove the old battery, and insert a new one, ensuring correct polarity. The design allows for easy removal and replacement.
To clean the receiver and sensors, wipe them with a soft, dry cloth. Avoid using abrasive cleaners, solvents, or excessive moisture, as these can damage the devices.
