11. Remote Control Fail-Safe Protection Setting

If the RC fail-safe protection is needed to be set, pls follow the below steps:

11.1 Write fail-safe protection data

After the successful connection of the airborne unit and ground unit, press and hold the SET button about 5S when there is SBUS data transmission.

When RX, TX, S1, S2, S3 all lights ON, it means entering Failsafe data setting mode, and then release the SET button.

Press the SET button briefly to switch to write failsafe data or turn off fail-safe, when RX and TX flash, it means the setting is successful.

Press and hold the SET button until RX, TX, S1, S2, S3 all lights are ON, which means Failsafe data has been saved and exit setting mode.

After finishing the setting, the current RC value can be stored in the airborne unit as a failsafe value, and will not be lost after power failure. S1, S2 and S3 will flash when failsafe
data is output. Please test whether the Failsafe data is written successfully by the flight control, GCS or servo.

11.2 Trigger Fail Safe Value
If the airborne unit does not receive SBUS data from the ground unit for 3 seconds, the airborne unit will keep outputting the Fail safe value written before, and the S1, S2, and S3 signal lights will flash until it receives SBUS data from the ground.

11.3 Turn off Fail-Safe Value
Long press the SET key (about 5S) after powering on the airborne unit. When all lights are ON, it means the Failsafe data setting mode has been entered, then release the SET key. Press the SET button briefly to switch to <write fail-safe data> or . When RX, TX, S1, S2 and S3 are off, it means turning off fail-safe function. Press and hold the SET button until RX, TX, S1, S2 and S3 are ON, it means fail-safe data is off.

11.4 Reset fail-safe data
If the user needs to reset the SBUS fail-safe data,
it enters fail-safe setting mode when there is RC SBUS data transmission. First, short press the SET button to cancel the fail-safe data set previously, then short press the SET button briefly. When the RX and TX lights flash, it means successful setting.

• By default, there is no fail-safe data output from the radio, it will continue to output the last received SBUS data after the data link is disconnected.
• Only the S-BUS channel that has input at that time will be triggered and deactivated fail-safe function. For example, if the S-BUS1 channel has data transmission and the S-BUS2 channel has no data transmission, pressing the key will only trigger and deactivate S-BUS1 fail-safe data.
• To set up fail-safe for both S-BUS1 and S-BUS2 at the same time, both S-BUS1 and S-BUS2 are required to have remote SBUS data transmission.
