That’s not necessary, we can help. We just want to pinpoint the lot your xNT has come from in the event there truly is a technical problem, which is pretty rare with our xNTs, but this does not mean you necessarily have a faulty unit.
Here’s what I can tell you, and what you can verify among the posts here from others immediately after installation; that even mild swelling will impede proper coupling. The range between the reader and the bio-glass encased chip should be within 2mm; therefore swelling and placement (depth) are factors in getting a proper read.
Give it a couple of days and try again. Most people are pleased to find that letting a brief amount of time pass usually solves this issue as swelling diminishes.
If you still find a lack of response. Come back and we have a few suggestions we can offer to validate the integrity of the chip.
