Transmitter LED status indicator
The RGB LED on the transmitter gives you at any moment an indication of your link status. Going from
green to yellow. Once you are in yellow your RSSI values are either very low or you are already in the
low-framerate link mode.

The on-board LiPo battery in the receiver is automatically charged every time the receiver is used. The
third LED indicators on the receiver’s front face displays the current state of the battery.
