Button Functions
There are three buttons on LiteRadio 3 radio transmitter.
- Power Button: Turn the radio transmitter off/on.
- BIND Button: Enter binding mode after radio transmitter is powered on.
- SETUP Button: Enter joystick calibration mode after radio transmitter is powered
on.
Power On/Off
POWER ON: Long press the power button on the radio transmitter for 3 seconds
until it beeps three times (do re mi) then release. The radio transmitter LED
ring will flash red quickly, then remain blue.
POWER OFF: A long press of the power button on the radio transmitter will turn
it off after three beeps (mi re do).
LED Indicator and Buzzer
The LED ring indicates the working status of the radio transmitter.
| State of the LED Ring | Reason | Solution |
|---|---|---|
| Red light solid on | The throttle joystick or switches are not in the lowest |
Lower throttle and switches 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
Red light breathes slowly| On charging|
Green light breathes slowly| Charge complete|
The buzzer will alarm twice, indicating a low be-charged.
Binding the Receiver
There are the steps to make the LiteRadio 3 enter binding status.
- Power on the remote control radio transmitter and wait for its system to load completely. LED ring is solid blue.
- Enter receiver’s binding mode, and wait for it to bind with the radio;
- Press the bind button on the bottom of the transmitter to enter binding stutas. The LED ring will be red and flash quickly.
- The LED ring will change to solid blue 5 seconds later when transmitter exits binding status. If not bind successfully, repeat the process above.
Switching Protocol
Note: Switching internal protocol is only available for CC2500 version
radio transmitter. ExpressLRS version can only switch to the external TX
module.
The CC2500 version could support 4 different internal protocols, including
Frsky D16 FCC, Frsky D16 LBT, Frsky D8 and Futaba S-FHSS, it also supports.
The protocol is indicated by the flashing times of the LED when power on,
before the buzzer alarms.
Cc2500 Version
LED Status| Protocol Version
Red Flash once| Internal Frsky D16 FCC (ACCST 1.X Version)
Red Flash twice| Internal Frsky D16 LBT (ACCST 1.X Version)
Red Flash Three Times| Internal Frsky D8
Red Flash Four Times| Internal Futaba S-FHSS
Purple Flash Three Times Quickly| Internal TX Module Off and Run External TX
Module
ExpressLRS Version
LED Status| Protocol Version
Red Flash once| Internal ELRS
Purple Flash Three Times Quickly| Internal TX Module Off and Run External TX
Module
To change protocols and TX module, here are the steps:
- Power the radio transmitter off;
- Press and hold the BIND button while power the radio transmitter back on;
- Then the flash color and times of the LED before buzzer alarms will change, according to the tables above.
Note: LiteRadio 3 CC2500 version only work with D16 ACCST 1.X Frsky protocol. So if you use a Frsky receiver with D16 ACCST 2.X version or ACCESS version, binding will fail.
Charging
LiteRadio 3 radio transmitter has a built-in 2000mAh battery. When the red light flashes twice and the buzzer alarms twice, indicates that radio transmitter is low battery and needs to be re-charged. Below charging method for reference:
- Turn off the radio transmitter
- Plug in radio transmitter with adapter by USB cable (5V output adapter is allowed).
- The LED ring breathes in red means charging, while in green means fully charged.
The continue working time for full charged battery is about 15 hours.
HID Joystick
It is the safest and quickest method to get started by using model practice simulator for starters. LiteRadio 3 radio transmitter supports most of simulators on market with comprehensive configuration.
Operation steps below:
- Turn off radio transmitter.
- Connect the transmitter to computer via USB data cable. Wait for the LED ring breathes in red or green.
- Install driver from PC automatically, prompt box pops up after successful installation. Then, radio transmitter works as joystick human interface device (AKA HID device) normally.
User needs to manually install driver if PC doesn’t install automatically or installed incorrectly. DO NOT power on the transmitter first and connect it to the PC. The USB port is invalid in this situation.
Joystick Calibration
The joystick data may offset after it has used for a period of time (if joysticks is hit by physical). User need to re-calibrate joysticks based on following steps.
- After powering on, press SETUP button on the back of remote control radio transmitter, it hears two “Bee Bee” sounds, and red LED flash quickly (two flashes each time), which means 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.
- Toggle the joystick to move to the top, bottom, left, and right joystick boundaries respectively (do not to press too hard, the joystick just needs to touch the boundary) and keep the position for 1-2S, then press the SETUP button one more time, we can hear a long beeping sound (about 3 seconds) from the buzzer again, and the red LED light stops flashing, indicating that the calibration of the joystick is completed.
BETAFPV Configurator
BETAFPV Configurator is utility designed to simplify updating, configuring and
tuning the radio transmitter.
