Finding a good spot for my sensor
I was approved for the MM warranty replacement including the CGM. I had the whole training and wore it for about a week until I got fed up. First of all I can't find a place to put it. I'm short and my torso is short. I had my pump on one side of the stomach and the sensor on the other and I couldn't sleep. Every time I turned over I was on something else.
It was also pretty inaccurate. I calibrated when I was supposed to. At one point it was reading 400 and when I tested I was actually 200 - major diff.
I really would love to like the system so I need your tips and hints.
Thank you!

Having a "weak signal" and "lost sensor" message means that the pump is too far from the sensor and it's loosing it's signal. It's not because it needs charging. If you get a "weak signal" for too long you will get a "lost sensor" reading. There's no need to remove the sensor. Just turn it off and restart.

It can't be too far b/c the sensor is in my upper thigh and the pump was either clipped to my bra or in my pocket. It seemed to be working fine after I charged it. It said "warming up". Then after an hour it said "weak signal" again. Now it says "warming up" again.
Do you think the sensor is bad? It's been a very hot summer and the ac is not on in my room while I'm at work a whole day.

I sometimes have weak signal and lost sensor warnings when I first start up mine. Even when I have my pump where I normally wear it (on my pants pocket). I usually move it around to different areas until it starts up and then move it back on my pants pocket. Then I don't have trouble after that.

i get intermittent weak/lost signal for now apparent reason. though sometimes for sleeping in a strange position. it can't hurt to change the charger battery and re-charge. i know that my signal weakens long before it will give me a low battery alert

When I hadn't used mine for a long time the MM rep told me to disconnect it for a minute and then place it back on the charger and let it fully charge.
My 2 cents on the placement of the sensor...I'm a thin person and the best places for me are on the back of my arms (need help to insert it), on the upper part of my backside and a little above my waistline on my back where there is enough tissue for a good pinch. Sometimes if I get a couple of lost signals or weak signals, I tape down the sensor part in the front with a bandaid or a small piece of Hypafix. I also put a small square of Hypafix under where the transmitter will be so it's not touching my skin directly and then I tape down the whole thing with occulsive dressing. When I put it on my backside, if I feel like it isn't flush to my skin because of curves or such, I place a small square of gauze under the transmitter. That way if it was pushed down it wouldn't pull up on the sensor and give me errors. So it would go, Hypafix, gauze, transmitter and occlusive dressing(sp?).

Well it was on pretty securely so I don't think that's the issue. It's frustrating but I'm not going to go crazy. After all, it's not like my pump isn't working so there's no safety issue. It's just annoying.
I let it charge for about 20 min this morning btw so I can rule out the charging issue.

Try taping down the front if the sensor. Maybe it's moving too much. I've had that happen before. You coukd also call Minimed. They can step you through some stuff. Many times they have gotten it to work for me. If its a bad sensor they will send you a replacement. I hope it gets working better for you.

Thanks. Well I finally got to the point where it asked me for my first calib. I'll see how it goes today.

The cgm was pretty accurate throughout the day. Of course I was so conscious about it reading everything that I was extra "good" with my eating today. So much so that it buzzed me with a low predicted. It was actually pretty handy b/c I was at work and wouldn't have stopped to test otherwise. I did feel like a low coming on so I grabbed a laffy taffy rope and went on with work. Naturally, since it's 20-30 min. behind, it buzzed me that I was actually low by the time I was recovering. I'm curious to see what goes on at night. I'm having a decent sized dinner so I'll see how that works as well.
I'm bummed that I can't use Care Link with my MacBook Pro.

What # do you have your low glucose set at? If, it's not warning you in time you can set it at a higher #.

I have it set at 75 to allow for the delay. Any higher and it will drive me insane. When I was low it was moderate, like a 68-70.
