X20/X20S and Ethos v1.5.0 User Manual
RF System
This section is used to configure internal and/or external RF modules, including the ‘Owner
registration ID’.
Disabling RF output
The internal and external RF modules can be disabled by holding the page key down during
system power up.
Owner registration ID
The ‘Owner registration ID’ is an 8 character ID that contains a unique random code, which
can be changed if desired. This ID becomes the ‘Registration ID’ when registering a receiver
(see below). Enter the same code in the ‘Owner registration ID’ field of your other
transmitters you want to use the Smart Share feature with them. This must be done before
creating the model you want to use it on.
Note on compatibility with OpenTX and EdgeTX
The ‘Owner registration ID’ is compatible with EdgeTX but only partly compatible with
OpenTX. It must have eight characters; it can have a mix of uppercase, lowercase and
numbers, but no special characters.
