procedure
1) Ascertain that the transmitter is in the PPM mode. Turn the transmitter off.
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 this receiver in the 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 LED on the receiver will
flash, indicating the binding process is completed. Turn off both the transmitter and receiver.
4)
Turn on the transmitter and connect the battery to the receiver. The GREEN 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.

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 antennas should be separated in the model, 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.
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.
