Question about Karcher DAB 9000CDI

Grüezi, I (pensioner) bought a DAB+ radio Karcher DAB 9000CDi from you via Ralph Bodmer, Wädenswil a month ago. Now I would like to ask if I can order a spare remote control from you? I had to throw away the last radio because the remote control buttons no longer worked. I would like to take precautions so that this doesn't happen to me again. When we have a radio, we have it for at least 10 years. (I had to throw away a 7000.-Fr electric hand organ FR7x from Roland after 3 years because the display was broken and there were no more spare parts). pierinokeller(at)gmx.ch
