The operating ranges of sets based on the RSU-K02/24V/H2 receiver depend on the type of transmitter that cooperates with the receiver and can range from 200 to 1000 meters.The ranges given apply to open space (without obstacles, when the receiver and the remote control "see each other"). If there are obstacles between the receiver and the transmitter, the operating range should be reduced accordingly for- wood and plaster by 5-20%,brick by 20-40%,reinforced concrete by 40 - 80% In the case of a large number of obstacles, we recommend using a retransmitter or higher power remote controls. In the case of metal obstacles, the use of radio systems is not recommended, consider installing the WLC-201 module , which allows you to bypass this type of obstacles.
