1.Make sure the firmware version numbers of the built-in or external ELRS TX Module
are consistent. The factory version is ELRS 3.3 without password.
2.The receiver is quickly powered on and off three times (power off again after the
light is on). The power does not stop for the third time, then waiting status light
changes to double flashes, and the receiver enters binding mode.
3.After the frequency binding is successful, the receiver LED light is always on and
the telemetry signal can also be received.
4.Receiver LED status meaning: Steady light means linking is successful, double
flash means linking is in progress.
Enter the TX Module parameter adjustment script and select the Bind option
The LED flashing slowly means that the tuner signal cannot be received or
the frequency is not paired
The LED gradually flashes into wifi communication mode, and the ELRS
firmware can be updated by connecting to wifi via mobile phone and computer

RGB color Status description
Rainbow color gradient, power-on self-test
Green and orange lights flash, entering WiFi upgrade mode
The red light flashes quickly and the radio frequency chip
is not detected
Orange double flash, binding mode
Three orange flashes, connected, but does not match the
settings in model matching*
Flashing orange slowly, waiting for connection
Steady on, connected. The color indicates the refresh rate,
as shown in the figure below
* If RGB orange flashes three times, you can enter the remote control SYS → TOOS → ExpressLPS → Model MatchON
(ID:X), or set it to Model Match OFF (ID:X).

D50 is a unique mode of ELRS Team900. Under the 200Hz refresh rate of Lora mode, the same data packet is sent four times repeatedly. The
receiving distance is equivalent to 200Hz. 100Hz Full achieves 16-channel full resolution output under the 200Hz refresh rate of Lora mode. mode,
the receiving distance is equivalent to 200Hz.

F1000 and F500 are refresh rates in FLRC mode, only ELRS 2.4G supports this mode, this mode provides faster modulation and lower latency, but the
reception distance is shorter than the ordinary Lora mode, suitable for competition: D500 and D250 is the refresh rate in DVDA (Deja Vu Diversity Aid)
mode, which works at the F1000 refresh rate in FLRC mode and provides a more reliable link connection in the presence of complex interference by
sending the same data packet multiple times. D500 and D250 indicate that the same data packet is sent twice and four times respectively.

Precautions for use
1. Pay attention to check whether the positive and negative poles are connected
correctly before powering on, so as to avoid short circuit damage to internal
components.
2. Make sure that the input voltage is within the specified range and correct to avoid
damaging internal components.
3. The temperature of the FC is relatively high. It is strictly forbidden to touch it directly
with your hands to avoid injury.
