About FS_ THR_ The problem of enable configuration

ArduCopter Copter 4.0
1

Hardware: cuav V5 nano

Software: copter-4.0.7

gcs：mp1.3.74

My configuration: FS_ THR_ The = 2, when the UAV is in automatic mode and the remote control loses contact, it triggers RTL, GCS prompts me that it has been abandoned,

I have configured it to be 1. As a result, when it is in automatic mode, the remote controller will still trigger RTL when it loses contact,

How can the remote controller lose contact and not trigger RTL in automatic mode? I want to configure FS for security_ THR_ The＝0

How can the remote controller lose contact and not trigger RTL in automatic mode? For security, I don’t want to configure: FS_ THR_ The＝0

I can’t understand the magic robot translation
