The relay in the receiver can be turned on or off with the two keys or be switched into two separate receivers with a key function each. The transmission mode is displayed by an LED. Multiple assignments are possible, that means several transmitter can control one or more receivers. The code is set with soldering pins. The transmission frequency of 868.95 MHz is in the new SRD band, and because of the low use through other radio services and the channel separation disturbance-free signal during use is guaranteed. The hand-held transmitter has general approval and can be used in the EU (with the exception of Greece) and Switzerland without registration or payment of fees.
