3. he 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 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 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 th
