The Dickert MAHS27-01 is a single-channel remote control with red buttons and LED, a frequency of 27.015 MHz AM, and microswitches inside (DIP-10).
To program this remote control, you must set the switches to match those of an already functioning remote control.
If you do not have a working remote control, set the switches to the same setting as those on the receiver/drive.
