Button Functions
There are three buttons on the remote control radio transmitter.
-
Power Button: Turn the transmitter off/on.
-
BIND Button: Enter binding mode after remote control radio transmitter is powered on.
-
SETUP Button: Enter joystick calibration mode after the remote control radio transmitter is powered on.
Power On/Off
POWER ON: Long press the power button on the transmitter for 3 seconds until it beeps three times then release. The remote control radio transmitter power indicator will quickly flash red, then remain blue.
POWER OFF: A long press of the power button on the remote control radio transmitter will turn it off after three beeps.
LED Indicator and Buzzer
The LED light indicates the working status of the radio transmitter.
|
State of the LED |
Camera status |
Solution |
|
Red light normally on |
The throttle joystick or switches are not in the lowest |
Lower throttle and switch to the lowest position. Turn to blue then. |
|
Red light flashing quickly |
The radio transmitter is binding |
Wait for completing binding |
|
Blue light flashing slowly |
Battery reaches the low voltage limit |
Charge the transmitter batteries |
The buzzer will alarm three times in a row, which indicates a low battery and needs to be re-charged.
Binding the Receiver
There are the steps to make the LiteRadio 2 SE enter binding status.
-
Power on the remote control radio transmitter and wait for its system to load completely.
-
Press the bind button on the back of the remote control radio transmitter. The power indicator will flash red.
-
If binding is successful, the LED light will change to blue. If not, repeat the process above.
Switching Protocol
The Frsky version could support 4 different protocols, including Frsky D16 FCC, Frsky D16 LBT, Frsky D8, and Futaba S-FHSS. The protocol is indicated by the flashing times of the red LED when power on, before the buzzer alarms.
|
LED Status |
Protocol Version |
|
Flash once |
Frsky D16 FCC (ACCST 1.X Version) |
|
Flash twice |
Frsky D16 LBT (ACCST 1.X Version) |
|
Flash Three Times |
Frsky D8 |
|
Flash Four Times |
Futaba S-FHSS |
Power the radio transmitter off; To change protocols (Frsky FCC D16, Frsky D16 LBT, Frsky D8, or Futaba S-FHSS), here are the steps:
-
Press and hold the BIND button while powering the radio transmitter back on;
-
Then the flash times of the red LED before buzzer alarms will change, according to the tables above.
Note: LiteRadio 2 SE only work with ACCST 1.x Frsky protocol. So if you use a Frsky receiver with ACCST 2.X version, binding will fail. For the moment, the Frsky ACCST 2.x protocol is private and could not be supported by LiteRadio until it is open.
Charging
The remote control radio transmitter has a built-in 1000mAh battery. It indicates a low battery and needs to be re-charged if the blue light flashes slowly. Below charging method for reference:
-
Turn off the remote control radio transmitter.
-
Plugin remote control radio transmitter with adapter by USB cable (5V output adapter is allowed).
-
The LED button red means charging, while light off means fully charged.
The continued working time for a fully charged battery is about 8 hours.
The radio transmitter does NOT support type-c to type-c cables for charging and FPV simulator.
HID Joystick
It is the safest and quickest method to get started by using FPV simulator for starters. LiteRadio 2 SE remote control radio transmitter supports most FPV simulators on market with comprehensive configuration.
Operation steps below:
-
Turn on remote control radio transmitter, blue light on, works normally.
-
Connect remote control radio transmitter to PC by USB cable.
-
Install driver from PC automatically, prompt box pops up after successful installation. Then, the remote control radio transmitter works normally.
The user needs to manually install the driver if the PC doesn't install automatically or installed incorrectly.
Joystick Calibration
The joystick data may offset after it has used for a period of time (if joysticks are hit by physical). User need to re-calibrate joysticks based on the following steps;
-
After powering on, press the SETUP button on the back of the remote control radio transmitter, it hears two "Bee Bee" sounds, and the red LED flashes quickly (two flashes each time), which means the remote control radio transmitter entered calibration mode.
-
Move throttle joystick and direction joystick to middle position, press SETUP button again, wait until the buzzer beep three "Bee Bee Bee" sounds, red LED light flashes quickly (two flashes each time), which indicates joystick data has been acquired and enter into the boundary value calibration mode.
-
Slowly rotate the throttle and direction joystick twice around the boundary of the joysticks(counterclockwise/clockwise), then press the SETUP button again, it hears a long ''Bee''sound about 3 seconds. And the red LED light stops flashing, indicating that joystick calibration is complete successfully.

How do we center the stick trim values in Betaflight?
Is there a Software to view all radio features and options on my laptop with the SE?
Where is the custom LiteRadio system software to program the switches for arming and modes?
I'm looking for the software as well for the LiteRadio SE
BetaFPV - where is the info? We all need info and software for this new TX.
PLEASE ADVISE.
Save as the others here. Is there a software that I can tune this radio?
Without software you can't even arm the drone with a switch. This update made the transmitter worthless. What about updates? What are you thinking?
Frustrating to say the least.. I'm trying to get a PPM signal out so I can connect it to a simulator..
try these

I got it to fly TinyHawk 2 (frsky d8)
Roll Gimbal Stop working after 10 hours of use, no custom software to program switches or channels, no opentx, no student port to fly with my kids.
Why is the new SE version so much worse than the previous one ? most of the great features from this radio are now gone.

What is the channel mapping for all switches on LiteRadio 2 SE with the Advanced kit?
