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 (, 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.

Andrew, for me when I go swimming a new sensor will skip some readings but if I've worn it through a shower or two it doesn't bother it at all and I've sat in the pool for several hrs with it not messing up. Good luck to you.

So i asked about the pump and got my answer now im gonna ask about the Dex, i wanna go swimming and am curious about their being a limit to be in a swimming pool or a certain amount of time i can be in it??

It lasted all night, customer service believed it to be a bad sensor. Second one on and looking good so far! *knock on wood* -am just so happy to have it!

thanks, just entered my 2 startup bgs and have the "???" ...but I'm guessing you just have to wait that out and hopefully it clears itself up :)

Hope it works better for you! =^)

@onesaint, i'll keep that in mind and try charging it overnight tonight
Comment by onesaint on September 13, 2011 at 4:51pm
@Helmut: Thanks, I think I'll postpone for a bit then. If the Tx is anything like the sensors, I can get 2-3x as long as recommended! =^)


@Kati: 3 hours isn't that long a time to charge the Rx. I usually leave it plugged in overnight on the bedside when its down to 1-2 bars. I find when the battery is full, it lasts, but when the bar indicator is low it drains quickly. You might try a 12-24 hour charge (especially with a new device).

@Seth thanks! That's what I had figured (conserve power) so when I started today I'd be good to go! .....lesson learned :)
Comment by Seth on September 13, 2011 at 4:14pm
@ Kati * I have had the issue of shutting down my receiver and the battery being dead when I turned it back on. I was trying to conserve power and it backfired. I have a friend on the Dex who has experienced this same thing twice.

Doug, I got a new starter kit including receiver. My insurance paid for it. Out-of-pocket prices are different from prices shown on insurance claims.
