## Long description

How to use
Attach the Yongnuo YN-E3-RT II to the camera hot shoe and secure it. Power on the controller and set the channel and group configuration to match the remote Yongnuo flashes. Use the on-camera controls to set group assignments and adjust flash output where supported. Test fire before shooting to confirm communication, then proceed with normal shooting workflows, adjusting group power or triggering mode as required.
Usage recommendations
For reliable operation, ensure the controller and remote flashes share the same radio channel and that firmware or compatibility requirements are met. When shooting in crowded RF environments, change channels to avoid interference. Allow space between transmitter and receivers where practical to minimize obstructions, and perform a short test sequence before critical captures to verify group settings and output levels.
