The SHT-12 Mini remote control allows for the operation of up to two functions of a radio module or receiver from the SH-12 radio series. Its compact design fits easily into any pocket and is also suitable as a keychain. A blue LED indicates the transmission operation. It not only represents transmitted radio signals but also provides information about the quality of the radio communication and the transmitter's supply voltage. An integrated buzzer acoustically signals confirmation from the receiver. If confirmation is disabled, any change in button status is reported instead. The remote control from the SH-12 radio series operates with extremely low interference due to its special transmission characteristics. With interference-resistant radio transmission and extremely short response times, ranges of over 250 meters can be achieved. For strong narrowband interference or the use of multiple parallel radio systems, the operating frequency can be adjusted to individual needs. The SH-12 radio series can operate in both unidirectional and bidirectional modes. In bidirectional communication, the transmitter automatically adjusts its transmission behavior based on the quality of the radio link. The transmitters are factory programmed with a continuous serial number, ensuring greater security and making each transmitter a uniquely distinguishable item.
