How to use

Mount the transmitter near the entrance at a convenient height and secure it using the supplied screws or adhesive tape.

Usage recommendations

For optimal performance, install the transmitter with a clear line of sight to the receiver when possible and avoid placing the receiver near large metal objects or sources of strong electromagnetic interference. Replace batteries in both transmitter and battery-operated receiver at regular intervals and after extended periods of inactivity to maintain reliable operation. When mounting outdoors, verify that sealing and mounting accessories are used to protect the transmitter from direct water exposure.
