Failsafe mode (D16 / LR12 only): Allows choosing between simply holding the last received positions, turning off pulses (like old PPM MHz receivers), or moving the servos to custom predefined positions. For custom positions a SET field will call the failsafe settings page, where the position can be defined separately for each channel. Select the desired channel, press ENTER to get in edit mode, move the control to the desired position, and press ENTER to save. In D8 mode this field is hidden, failsafe needs to be set on the receiver as described in the receiver's manual.
