Before binding the ORX 2.4GHz Transmitter Module, check your receiver specifications and
select the proper ORX 2.4GHz Transmitter Module working mode. The working mode is
indicated by the LED on the back of the ORX 2.4GHz Transmitter Module. The ORX 2.4GHz
Transmitter Module only operates in a single working mode. It’s a little different from
JR/Spektrum transmitters. That means that the ORX 2.4GHz Transmitter module mode must be
changed manually when switching between DSMX and DSM2 receivers. If you have both DSM2
and DSMX receivers then you will need to remember the correct ORX 2.4GHz Transmitter
module mode for each receiver and manually switch it before turning on the receiver. In every
case, before you turn on your receiver, you need confirm the ORX 2.4GHz Transmitter Module’s
working mode is correct for that receiver. Pay close attention to the receiver’s LEDs to ensure
that it is working properly. Please remember that operating the ORX 2.4GHz Transmitter
module in an incorrect working mode may result in an inability to drive your servos or it may
drive them incorrectly, this is very dangerous. If the transmitter and receiver are not
functioning together properly it may result in a crash or injury.
