The function of the four buttons (A, B, C, D) falls from apparently different: However, there is a problem has been found. I wanted to use this remote control button function, ie as long as the signal is transmitted, which is closed at the receiver module built-in relay. So that works with the original remote control and with this also - but only over the C key Strangely, but never with A, B or D. In this case, each key the same source signal has been programmed. I've been programming determines repeated 30 times - each time with exactly the same result (the keys can be but always properly programmed and send afterwards also).
Test, I have from another provider in the same remote control (though with only 2 channels) found me again. With this the desired operation then has worked flawlessly with both A and B Tastem.
I do not know is if my 4-channel model is defective or actually a technical difference between the 4 channels exist.
