I own a 2005 Coime concrete pump, very similar to CIFA. The remote and the recieving unit are made by Autec. The problem is that the remote doesn t connect immediatly when you try to start it. There are moments when I have to try to start it for 5 mins and there are times when I have to wait 30 mins. Once connected, it doesn t loose signal, it works perfectly fine and if I disconnect, it reconnects immediatly. But after an hour or two, when I arrive to another site I have the same problem. Does anyone have any idea what it could be?
