Receivers other than T-FHSS
1
Bring the transmitter and the receiver close to each other, within
20 inches (half meter).
2
Turn on the transmitter.
3
Turn on the receiver.
4
Push the tactile switch of the receiver.
When the link is complete, the LED in the receiver changes
to solid green.
Precaution:
If there are many Futaba S-FHSS/FHSS systems turned on in close proximity to the R2104GF, your re-
ceiver might not link to your transmitter. In this case, even if the receiver's LED stays solid green, unfor-
tunately the receiver might have established a link to one of other transmitters. This is very dangerous
if you do not notice this situation. In order to avoid the problem, we strongly recommend you to double-
check whether your receiver is really under control by your transmitter by giving the stick input and then
checking the servo response.
*Please refer to the table below for LED status vs receiver's condition.

Warning
After the linking is done, please cycle receiver power and check if the receiver to be linked is re-
ally under the control of your transmitter.
Do not perform the linking procedure with motor's main wire connected or the engine operating
as it may result in serious injury.
