Basic functions
Introduction to Switches and Keys
Three-position power switch: This switch allows you to switch the power supply way of the RF module: internal power supply (Int), power-off (Off), and external power supply (Ext). The external power supply is realized through the XT30 interface. Five-way key: Up, Down, Left, Right and Center. The functions of the Five-way key are described below. It should be noted that a key is not valid when the input signal is recognized as a serial signal.
Up: Forced update and input signal settings
Center: Switching RF system and Binding Right: Switching RF Models & Searching a receiver automatically
Left: Setting RX interface protocol
Down: Reset to factory and Failsafe
Up and Down are used for selection. The Right is used for confirmation. The Left is used for exit.
Note: In the key operations, if you hear a “Click”, it indicates that the action is valid. And the key operation is not cyclic.
Power Supply of RF Module
The RF module can be powered in three modes: Type-C interface, and internal power supply or XT-30 external power supply. · Powering through the Type-C interface is the first priority. In the power supply
through the Type-C interface, the RF module is not off when you switch the power in case of internal power supply or external power supply. · In the internal power supply or external power supply (instead of power supply through the Type-C interface), the RF module will restart when you switch the power.
When you remotely control a device, please do not use Type-C interface to supply power to the RF module to avoid losing control of the device. When the RF module is powered by Type-C interface, the RF module will automatically reduce the output power to avoid damage to the USB interface of the connected device. After the power is reduced, the remote control distance will be shortened.
External Voltage Alarm
When the RF module is powered by a lithium battery connected through XT-30 interface for a long time, a voltage alarm function provided in the RF module will remind you of replacing the battery in time. When the RF module is powered on, the system automatically detects the power supply voltage and identifies the number of battery sections and the alarm voltage value according to the voltage. When the system detects that the battery voltage is lower than the corresponding alarm value, it will report an alarm. The specific table is as follows.

>21.3V
6S lithium battery
Corresponding Alarm Voltage 3.65V 7.3V 11V 14.5V 18.2V 22V
High Temperature Alarm
The temperature of the RF module may rise due to the use environment or long time working. When the system detects the internal temperature 60 , it will give an audible alarm. If the controlled model is in the air at this time, please turn off the RF module after the return. You can reuse the model after it cools down.
Low Signal Alarm
When the system detects that the received signal strength value is lower than the preset value, the system will give an audible alarm.
Firmware Update
The RF module can be connected to the PC through Type-C interface to update the firmware through the FlySky Assistant. The corresponding states of the LED
flashing in the update process are described in the following table. The update steps are as follows:
1. At PC side, after downloading the latest FlySkyAssistant V3.0.4 or later firmware, then start it.
2. After connecting the RF module to the PC with Type-C cable, finish the update through the FlySkyAssistant.
