I have a 4PK, the red light always turn on (it should be blue when normal)the tx and I can't blind with my R604FS rx.
The tx display shows RF sign but the receiver doesn't seem to have signal pickup and there is no green light showing on the receiver while pushing down the switch on the rx. What seems to be the problem?

Go to RXSYS in the menu and make sure you're set to C2.

Yes, no matter C1 and C2. it is still showing red light and not able to blind with rx.

I'm guessing you tried this but I had this same problem until I figured out I had to turn off my radio for the setting of c1 and c2 to take effect.
