For users of a Dexcom Continuous Glucose Monitoring ("CGM") device

Just as a reminder with the recent release of the new Dexcom G4 to the US market--it is NOT okay to post about previous models or older sensors as being 'for sale' on this site.

It is a violation of the Terms of Use because it is a prescription device, and any such efforts will unfortunately be removed.

We encourage you to donate supplies to non-profits such as the Charles Ray III Diabetes Association (http://www.cr3diabetes.org), which accepts unexpired glucometer and insulin pump supplies, or alternatively you may talk to your physician's office or other local medical group to discuss donating them to those in need of assistance.

Thank you all for kindly refraining from this activity.

To all Dexcom cyclists: I just ordered off the internet at velotrac.com a bento box that zips shut, but the best thing is that it has a see through window insert where they mean for you to put your ipod, but I just put my receiver
into that pouch and punch it on while I am riding, and I can see my bg right away! Bravo..........

Thanks,Scott

All you need to do is "stop sensor" then "start sensor". No need to wait or remove the transmitter.

I've read where several people wear their sensors for more than one week. I'd like to try and wear my sensor for an additional week. Do I just turn the sensor off and back on, or do I have to remove the transmitter and put it back on as well? Do I need to leave the sensor off for any particular length of time? Thanks for the help

Thanks, Jay, and Luca. ;)

It would make no sense to also have a receiver and the logic to control the transmitter within the small device that we attach to the sensor's cradle, Rick. Jay is right, the transmitter sends out a signal automatically when it is connected to a sensor, and there is no way to turn it off.

I've been able to squeeze 20 months of life out of my first transmitter, I guess I could have done more but I just did not want to risk, so I installed the new one even if there were no signs of any degradation.

This chatter lead me to get out my Dexcom manual. The RECEIVER, when shutdown, only keeps the clock operating. It has NO transmit ability. The TRANSMITTER only transmits. It has no receiver in it. The signal is sent every 5 minutes. This information came from section 10 of the Dexcom 7+ Users Guide on specifications.

The transmitter consumes very little energy in it's "background" State (listening for commands from the receiver; I think that the two commands are "RU There?" and "Give me your current raw data value".)

After receiving such a command, though, it uses considerably more energy to make the measurement... and, especially, to Transmit the value through the radio.

Communications stop, but I'll guess that this "background listening" job is 24x7.
Comment by Kelly Rawlings on February 16, 2011 at 12:45pm
The receiver definitely continues to use energy when in shutdown mode. Not sure what that does to the transmitter.
Comment by powell1973 on February 16, 2011 at 12:19pm
I was wondering if you take a break from wearing the Dexcom and shut it down, does the transmitter shut down also. Will this enable me to get longer life from the transmitter?
