Starting a new sensor

Quick question: does the receiver need to be in range during the 2 hours warm up time?

Yes, though it won’t ruin the process if every once in a while the sensor goes out of range during calibration.

Ouch…I’m heading to the gym while doing this and will be out of range for 1 hour…should I do another restart when I get back? I’m right in the middle of it!
Thanks for your answer!

I guess you can see if it will work, or not. Worst case if it doesn’t work you can Stop Sensor and then restart again. I’d usually recommend doing the 2-hour calibration by the book, though.
