Bind procedure

procedure
1) Ascertain that the transmitter is in the PPM mode. Turn off the transmitter.
2) Turn on the transmitter while holding the F/S button on the transmitter module (Ensure that both switches on the
transmitter module are OFF when using D8R-II plus in two way mode). Release the button. The RED LED on the
transmitter module will flash, indicating the transmitter is ready to bind to the receiver.
3) Connect battery to the receiver while holding the F/S button on the receiver. The RED LED on the receiver will
flash, indicating the binding process is completed. Turn off both the transmitter and the receiver.
4) Turn on the transmitter and connect the battery to the receiver. The RED LED on the receiver will indicate the
receiver is receiving commands from the transmitter. The receiver/transmitter module binding will not have to be repeated,
unless one of the two is replaced.

2.2 2.2 Range Range check check
2.2 2.2 Range

Range check

check
A pre-flight range check should be done before each flying session. Reflections from nearby metal fences, concrete
buildings or trees can cause loss of signal both during range check and during the flight.
The following steps are to be followed to perform the range check of the model before the 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, and do not touch the ground.
3) Place the antenna of the transmitter in a vertical position.
4) Turn on the transmitter and the receiver, press the F/S button of the transmitter module 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 of the transmitter module for 1S-4S to exit range check mode, RED LED will be back on,
indicating normal operation is back.

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. D8R-II plus supports failsafe function for all channels.
