*Transmitting Distance: Transmitting distance is measured LOS (line of sight) with little radio interference, actual distance may vary greatly depending on the installation and operating environment.
** High Security Rolling Code (HCS301): With Kelvin Anti-Code Grabbing technology the transmitter's code changes every time the transmitter button is pressed. This prevents the electronic theft of the code.
***Certificate: Our products are certificate compliant, for more information on either CE or FCC ID, please contact us.
