Tvheadend

Hello,

i have an Dinobot 4k+ Box with Android & TVHeadend.
As i´m running DV Inputs i get Hisilcon AVL68XX for Signal Input DVB-C but there is no button to save und start Channel search.
If i push the butoon save at Hardware Configuratin it says saved.
How to get redy for Chanelsearch????

Thank you!
