Do I have to re-link an Echoflex Switch after replacing its battery?
I just replaced or added a battery for an Echoflex control device. Will it lose its link data? Do I have to re-link it?
No, you do not need to re-link anything that was previously linked. The link is based on each device's uniquely coded radio ID.The output devices store a list of linked radio IDs that is only cleared if you follow unlinking steps or clear the output device's configuration.
