Morning everyone! I have a couple of questions on the G4. Does anyone in here exercise with it on? If so, do you loss signal?
I'm trying to find the best way to exercise without losing signal.
Yesterday I went on a 5K run but 10 minutes into my run I lost signal. Before that I had notice my BG dropping. I decided to stop and was mad at myself for losing signal. Any suggestions?!?!

I exercise all the time with it, but I don't run. I walk, play tennis (which I suppose you need to run every once in a while) and I ride a stationary bicycle. I keep the receiver in the case that came with it when I exercise. And while the vast majority here hate the case, I have not lost signal once while exercising. Some other folks here swim for exercise and will lose signal in the pool but that is to be expected.

I run with mine every day without losing signal. It's possible that your lost signal during your run was an anomaly? Did your transmitter come off from perspiration? Did you get the signal back? If you lost signal for just a short time and regained it shortly thereafter, I wouldn't worry about it. If your transmitter came off your body I would look at tape/adhesive options.

I do long and very bumpy (VERY) mountain bike excursions with my G4 on and don't lose connectivity.

Every once in a while I lost connection with my 7+ while on rides, but sometimes I'd lose connection just sitting at my desk as well.

I don't think it's anything to worry about, but if it keeps happening you might want to a) swap sensors or b) ask about a new receiver.
I wear mine when I'm white water kayaking, put the receiver in a small mobile phone dry case in my dry suit chest pocket and turn up the alarms. It works fine for me, I never loose signal. My activity can last from 2 to 6 hrs.

It's not just you. Depending on the level of activity during karate I will loose it for a reading or two. Example, other day we did 100 jumping jacks, followed by burpees, sit ups and push ups. For that entire period I had no readings. As soon as I was not jostling myself around they came back no problem.

Please see this thread:

This is a known problem, provisionally related to repetitive motion while wearing synthetic clothing over the G4 transmitter.

I am waiting my g4 this week, but with my dexcom 7, I actually use an armband slip that is made for my phone/ipod. Might be how/where you are carying it? I know the g4 is supposed to have an expanded distance, but sometimes I would lose signal when it was in my pocket?

I workout in a gym twice a week. No problems here with G4. My trainer keeps the receiver on his clipboard and monitors closely. I have frequent hypos if CHO ingestion is not well planned and managed.

Hi Roberto

Did you solve your problem!?
I´m having the same problem; every time i start running, i loose my signal.
Usually i run with a synthetic shirt, do you know if this have something to do with it!?

Maybe try a case? I was just thinking that immediately after getting my G4 I got a case for it that's fabric. Maybe that's why I've never lost signal during runs, walks, biking, etc. My case is girly, but I'll post it here in case any women are interested:

You guys will have to find your own :)

From what I've heard it has to do with the type of fabric ones shirt is. I just use a cotton shirt and it seemed to fix the problem.
