The following steps are to be followed to perform the range check of the model before flight:
1) Place the model at least 60cm (two feet) above non-metal contaminated ground (e.g. on a
wooden bench).
2) The receiver antennas should be separated in the model, as described in the receiver manual,
and not touching the ground.
3) Place the antenna of the transmitter in a vertical position.
4) Turn on the transmitter and receiver, press the F/S button of the transmitter for 4 seconds to
enter range check mode, the RED LED of the transmitter module will be off, GREEN LED will flash
rapidly, and the BEEPER will sound. The effective distance will be decreased to 1/30 of full range.
5) Walk away from the model while simultaneously operating the controls on the transmitter,
confirming that all controls operate normally to a distance of at least 30 meters (~30 yds).
6) Press the F/S button for 1S-4S to exit range check mode, RED LED will be back on, indicating
normal operation is back.
2.3 Setting failsafe
Failsafe is a useful feature in which all controls move to a preset position whenever the control signal
is lost for a period of time. D6FR supports failsafe function for all channels. Follow the steps below to set
failsafe positions for each channel:
1) Bind the receiver first and turn on both the transmitter and receiver;
2) Move the controls to the desired failsafe position for all channels;
3) Press briefly the F/S button of the receiver (less than 1 second), the GREEN LED of the
receiver will flash twice, indicating the failsafe position has been set in the receiver.
To disable the failsafe function, re-bind the receiver.

3. How to switch between two PPM modes
Turn the transmitter off, connect the battery to the receiver, press the F/S button of receiver for 6
seconds and then release. The red LED will flash fast in HS Mode and slow in FS Mode. The mode
alternates each time this procedure is done.
Warning: HS mode is only applied for high-speed digital servos. Other servos should select
FS mode, otherwise servos will get hot and may burn out.
