Obviously if it was a new recent shipment from Emlid, I am sure they work with you on a replacement. But assuming this is a older used RS2. Good luck with Emlid providing any sort of replacement parts. : /
I noticed a SLEW of used FOR PARTS OR NOT WORKING Emlid RS/RS+/RS2/RS2+ units for sell on Ebay recently for DIRT CHEAP… they are all obviously gone now.
