Marantec digital radio hand transmitters are available with either four or two buttons with various corresponding functions.
For example, you can use one radio hand transmitter to control several doors or gates, even if these are fitted with openers made by other manufacturers, or also to switch on the opener lighting. The transmitters fit perfectly into your trouser pocket or handbag or onto the sun visor in your car.
An electronic button lock function effectively prevents the button from being activated accidentally.
