Hi,

I mean it does measure the strength of the signal it receives. It can be valid but weaker. On the display are the signal strength in % for each receiver.If one receiver is 100% and theone it is using drops to 95%, it willswitch to the 100% one.

If you have a power failure on a receiver you would get 0% signal so it would switch to the other receiver. Putting it simply, If both are working fine but one has a weaker signal than the other for whatever reason, it switches to the stronger signal.

In a failsafe condition, the receiver is still able to send a failsafe signal. With the RRS, you set a spare channel to do this. The receiver goes to FS and the channel you selected for FS switches over and this is the FS signal the RRS detects and will automatically switch to the other receiver.

Does this answer your question?
