Link Procedure
Each transmitter has an individually
assigned, unique ID code. In order to start
operation, the receiver must be linked
with the ID code of the transmitter with
which it is being paired. Once the link is
made, the ID code is stored in the receiver
and no further linking is necessary unless
the receiver is to be used with another
transmitter.

This is a rare occurrence. However,
should another T-FHSS transmitter/
receiver be linking at the same time,
your receiver could link to the wrong

recommend you to double check
whether your receiver is really under
