Quick Question - When we start a new session on our Dexcom ....and it takes a couple hours or so.....does the receiver need to be near the sensor or can it be in another room charging until it asks for the 2 start up blood sugars? I have wondered this for months and want to know what is best! And why does it take so long to start up? hummm???
Thanks so much!
You must *always* have the receiver close to the transmitter and sensor during the two hours of calibration, like you would normally do.

My diabetes educator just texted me 2 min ago that it can be away from the body and sensor for the 2 hours....boo....I wonder if its in the booklet we got with the Dexcom....is that where you read it or were you told by someone? Thanks so much!
Thank you Luca - I finally found my "start up" guide. You are correct. It says - Helpful hint - keep your receiver and transmitter within 5 feet of each other for best communication, even during your Start up period. There is my answer! Happy Holidays
Nah ... I use the Dex for two weeks. During the second start-up, I leave the receiver charging in the bathroom and go about my usual business. Never has been a problem .. the receiver doesn't "know".
Yes Jeff, if “the receiver doesn’t know” what the sensor and transmitter are measuring, then how can it perform the calibration?
Maybe you have a small place with thin walls and the transmitter blasts enough signal to be heard by the receiver, but I would definitely discourage this behaviour. The calibration is the most important phase in the life of a sensor, better not mess it up, IMHO.
But YMMV, as always.
Ciao, Luca
Actually, I often leave the leave the house. As far as I know, the calibration takes place AFTER the 2 hour period and after you enter the two BG readings.
This not how I know it, Jeff. My understanding is that one should have a fairly stable BG reading during the two hours, and the receiver will read the figures sent by the sensor thru the transmitter and create a baseline. Then the two readings allow the receiver to put a number to the baseline that it has created during the two hours of calibration.
If anyone knows more, or wants to ping Dexcom about this, I am very curious to know the truth.
Ciao, Luca
All I can say is that this has been my experience. I would love to hear a response from Dexcom but none of these companies seem to answer direct questions. What you say sounds reasonable but I find that it doesn't seem to matter to me.
Thanks Luca.
