K8057 Reciver problem

Few days ago I get the K8057 Receiver and K5059 transmitter, everything is fine except that if you switch on the ch1 and then ch2 both ch are on :frowning:. Because I need this for my garage doors this function is unsuited for my demands (the garage doors are jammed). Is it possible somehow, for this kit, to make some modification (with PIC or something) that ch1 and ch2 can’t be on at the same time?!

thanks in advance

Sorry, no modifications. You could wire the relays in such a way that one interrupts the other. It will depend on the requirements of your garage door lift if this is an option or not.
