This is a HyDom garage door, model ST3-HD3

HYDOM transmitter model ST3-HD3 3 button, rolling code at 433.92 MHz.

This emitter comes with the standard code, so it won't work in garages where an installer has put in a custom code. It is 100% compatible with the receivers and receiver cards of this website Tecnoparking. Activation can be done by the receiver button or remotely by radio with a pre-programmed control.

ATTENTIONThe following: The ST3-HD3 model has been replaced by the TERRA model of the same characteristics.
