Turn the transmitter off. 2) Turn the transmitter on and enter MENU page, select V8_Mode or D_Mode to work with corresponding receiver you are using (see compatibility chart above). Select Bind. 3) Connect battery to the receiver while holding F/S button on the receiver. The RED LED on the receiver will flash, indicating the binding process is completed. Turn off the transmitter and receiver. 4) Turn the transmitter on and enter MENU page, select Normal. Re-connect battery to the receiver. The RED SOLID LED on the receiver will indicate receiver is receiving commands from the transmitter. After above steps are completed, both the transmitter and receiver are ready to be used. The bind procedure will not have to be repeated unless one of the two is replaced.   3.3 Range 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 the range check and during flight. 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’s antennas should be separated in the model and not touch the ground. Place the module antenna in a vertical position. 3) Turn the transmitter on and enter MENU page, select R-CK, connect battery to the receiver. The effective distance will be decreased to 1/30 of full range. 4) Walk away from the model while simultaneously operating the controls on the transmitter, confirming that all controls operate normally to a distance of 1/30 of the full range. 3.4 Signal Loss Indicator and Failsafe Setting In some special circumstances, such as strong interference, the signal may be lost. When signal is lost in a short period, the receiver continues to try to search for the transmitter, at the same time it keeps the last command from the transmitter, until a new command is received. 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. Follow the steps below to set failsafe before flight: 1) Bind the receiver first and turn on both transmitter and receiver; 2) Set all transmitter controls to the desired failsafe position; 3) Press briefly the F/S button of the receiver (less than 1 second), the transmitter module will make a long “beep” (for D8R only) or 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. Follow the steps below to set failsafe during flight: 1) Bind the receiver first and turn on both transmitter and receiver; 2) Enter MENU page, select F/S to enter failsafe sub-page, press button B to set failsafe at the desired failsafe position during flight. Note: If FrSky DHT-U, sensor hub, sensors and LCD-fdd_lite are applied, please upgrade your telemetry module and D8R receiver with FrSky newly-released ROMs, which can improve the reliability and stability of data feedback after the transmitter’s reset.
