The RT21 hand transmitter is available in a 1-channel or 2-channel version.

This variant features a transmitter-learns-transmitter (TLT) function, which allows the transmission codes to be transferred from one RT21 (TLT) to another RT21 (TLT). By transferring the transmission codes, both transmitters always trigger the same function in the receiver. Any number of transmitters can be coded the same way.

An easily visible LED lights up when the battery needs to be changed.
