VM130T does not work with K8009

Hello dear vellemann User,
I have a technical question about the product VM130T RF Remote Transmiter. According to her, the product would have to be compatible with K8009: Multifunctional watch. Unfortunately, I have no success and can not control the K8009 multifunctional clock with the VM130T, have already received the second remote control from the company Altron from Switzerland because they assumed the product was defective, but had no success despite the exchange. Can it be that the product is faulty? or did I miss something? Could you please help me?

Many thanks in advance for your reply,

TSW
