Dynamic transmission power
The system can automatically choose the power level most suitable for the situation at hand. For instance,
if you fly close to the transmitter you normally only require minimal TX power and the system will
therefore switch to the lowest possible TX power level required to maintain a good up-link.
The maximum TX power level the system is allowed to use, can be defined by changing “Max Power” in the
configuration menu.

Operating modes
Operation mode is where you can set the crossfire in an ultra-low update rate, high range mode. Normally
the Crossfire switches from 150Hz to 50Hz, depending on the link quality. With  Forced Telemetry  enabled,
it will now only switch between 50Hz and 4Hz mode. Only enable it if you know what you are doing.
Note: Forced Telemetry is not meant to be used in normal conditions. The best practise is to not use it.
Transmitter LED status indicator
The RGB LED on the transmitter gives you at any moment an indication of your link status.
