OTA], power on the receiver, select the RX, go to the [ENTER], complete the flash process, the transmitter will display [Flash
successful]. Re-power the receiver and wait for 3 seconds, the Green LED starts flashing indicates the receiver works properly at the
momemnt.
Note: Update the firmware after the receiver gets bound.
How to enable/disable the receiver telemetry
-- For Taranis X-Lite Pro as an example, go to the External RF, select the Receiver, press the ENTER button, select the options,
and enable/disable the telemetry.
How to Set Failsafe mode (on the transmitter)
There are 3 failsafe modes: No Pulse, Hold, Custom
• No Pulse: on loss of signal the receiver produces no pulses on any channel. To use this type, select it in the menu and wait 9
seconds for the failsafe to take effect.
• Hold: the model will maintain the last position after the signal is lost. To use this type, select it in the menu and wait 9 seconds for
the failsafe to take effect.
• Custom: the customized position of each individual channel. The model will move to the pre-set position after the signal is lost. Move
the cursor to [Failsafe ][Custom][Set] and press ENTER, you will see FAILSAFE SETTING screen below. Move the cursor to the
channel you want to set failsafe on, and press ENTER. When moving the crresponding sticks or switches, you will see the channel
bar moving. Move the channel bar to the place you want for failsafe and long press ENTER to finish the setting. Wait 9 seconds before
the failsafe takes effect.
Note: If failsafe is not set, the model will hold the last position after signal is lost, thus it may fly away or cause injury.
