5. Low Batte Ale and Charging
LiteRadio 3 Pro radio transmitter has a built-in 2000mAh batte, therefore, there is
no need for an external batte. The normal voltage of batte is 4.2V-3.4V. The
screen will display the batte voltage in real-time.
When the batte voltage is less than 3.4V, the radio transmitter's low-voltage alarm
will be triggered: the batte icon on the screen ashes with the buzzer vibration
and the speaker emits a "dididi" sound. Please turn it o in time to recharge it.
Charging procedures are as below for reference:
● Turn o the radio transmitter;
● Plug the USB cable with adapter into the remote control radio transmitter (5V
output adapter is allowed);
● LED ring displaying red indicates that the remote is charging. The LED ring
turning o means the remote is fully charged.
The continuous working time for a fully charged batte is about 15 hours (100mW
transmit power);
Turning o a fully charged radio, the batte capacity can be kept at about 80% for
30 days.

6. HID Joystick
When LiteRadio 3 Pro connected to PC, it can be used as a USB gamepad and
practice model simulators. Specic steps:
● Turn on the radio transmitter;
● Connect the transmitter to the computer via USB data cable. The LED indicator
will turn green when the radio transmitter is fully charged, and turns red when it is
out of power;
● The prompt of the radio transmitter will be popped up, please kindly choose"USB
Joystick (HID)";
● The PC will automatically install the driver. After the driver is installed
successfully, a prompt will be popped up, indicating that the computer has
successfully recognized the radio transmitter and can use it normally.
Users need to manually install a driver if the PC doesn’t install automatically or is
installed incorrectly.
Note: When the remote is turned o and connected to the computer, there is no
signal output from the USB po, and the Joystick function cannot be used.
