BindingProcedure

Bindingistheprocessofuniquelyassociatingaparticularreceivertoatransmittermodule.Atransmittermodulecanbe

boundtomultiplereceivers(nottobeusedsimultaneously).Areceivercanonlybeboundtoonetransmittermodule.Follow

thestepsbelowtofinishthebindingprocedure.

1. TurnonthetransmitterwhileholdingtheF/SbuttonontheXJTmodule(seeModeandCompatibilitytable

above).Releasethebutton.TheREDLEDontheXJTmodulewillflashandGREENLEDON,indicatingthe

transmitterisreadytobindtothereceiver.

2. Connectthe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(pleaserefertothecorrespondingreceiver’sinstructionmanual

fordetails)

3. Turnoffboththetransmitterandthereceiver.

4. Turnonthetransmitterandconnectthebattery.TheGREENLEDonthereceiverindicates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.

Note:Afterbindingprocedureiscompleted,recyclethepowerandcheckifthereceiverisreallyundercontrolbylinked

transmitter.

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.



Followthestepsbelowtoperformtherangecheck.

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. Themoduleantennashouldbeinaverticalposition.

4. Turnonthetransmitterandthereceiver,presstheF/SbuttonontheXJTmodulefor4secondstoenterrange

checkmode,theREDLEDwillbeoff,GREENLEDwillflashrapidly.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toconfirmallcontrols’

normaloperation(pleaserefertothecorrespondingreceiver’sinstructionmanualfordetails).

6. PresstheF/SbuttonontheXJTmodulefor1~2secondstoexitrangecheckmode,REDLEDwillbebackon,

indicatingnormaloperationisback.
