-3. Ensure the quad and transmitter has connected successfully.
-  - The RC transmitter should have GAUI 330X selected and displayed on the screen. With the quad and transmitter on, the unit on the quad labeled Spektrum AR610 should have a blinking orange light or solid orange light (It is easier to see the orange light from the top of the receiver). If this is not blinking or solid, try restarting the quad and transmitter with the transmitter closer to the quad.
