       Nor/Rev set up:   

       Remarks: every channel Nor/Rev will be sound and LED indicated   

       Set up Steps:   

       -Turn On: short press the power switch and keep lowest stick   

       -Enter set up mode:long press Ch5/6 button simultaneously for 10s   

       -Throttle reverse set up:keep the throttle stick at center and lower the stick to reverse the throttle once   

       -Aileron, Elevator,Rudder. Move the stick to desired reverse channel   

       -Nor/Rev Ch5/6. Long press the desire reverse channel for 1s   

       -Cancel Nor/Rev set up, Long press the Ch5/6 for 3s   

       Communication Protocol:   

       -Sbus/ppm selectable: Led flash rapidly when bind switch is pressed, LED keep solid light on when binding succeed within 30s is Sbus. If Led flash slowly when binding succeed within 30s is ppm   

       -Receiver signal indication: Normal Sbus signal Led keep solid light on, Normal ppm signal Led flash once every 10s, Led off when no signal is detected.   

       Set up steps:   

       -Turn on the radio and press binding switch, enter pairing mode when Led flash rapidly   

       -Turn on the radio, Long press the binding switch by 3s until Blue Led flash slowly to hear a sound "Beep"then release the button.  Blue Led flash rapidly to enter the pairing mode   

       -Binding succeeded when the Led flash from rapidly to solid light on. Reboot the receiver. Press binding switch to complete the pairing   

       Receiver Antenna:   

       -Keep antenna upright or it will lower the range of reception   

       -Keep both antenna in 90 degree   

       -Carbon fibre and metal components of the model will harmful to the reception of the receiver.Under this circumstances, the best antenna position should be keeping away from them and put correct angle of the antenna to obtain better reception   

       -Negative: Negative to ground   

       -Positive: Connect to 5v power   

       -S signal: Sbus/ppm output signal
