How to change the power and Channel?
If you are using it with a Betaflight Flight Controller buit-in Betaflight OSD, you can manage the Atlatl's transmit power and Channel from within OSD.
More details about operation steps, pls read the manual.

Channel-Change Button: 
The Atlatl is intended to be configured via Telemetry. If you can not use Telemetry, you can change Channels by using the Button buit-on the surface of VTX. 
The button is intended only as a fallback option for when Telemetry is not avaliable. It would be very tedious to use the button as the primary means of configuring the Atlatl.
 

1. Hold the button down for 2 Seconds to swtich from Telemetry Mode to Button Mode.
2.Then Press the button one time to change to the next channel. There is no separate " Band" and " Channel" function.  The Atlatl will simply step through all 40 Channels that it support.
