Another new way to restart a G6 Sensor

I found another way to restart a sensor. I just used the method to restart mine so it does work. I am not sure it’s easier. I was able to do it with my one hand but just barely. I had to brace the sensor with my fingers so it wouldn’t move and used my other fingers to insert a contour test strip. If it was on your stomach where you could use two hands it seems like it would be fairly easy. Hold it still with one hand and then use the other to insert the strip. I used the contour test strip but it looks like he used a LIbre test strip.

  1. Stop sensor or wait for it to end.
  2. Insert test strip into the narrow end where there is a slot, Contour or LIbre which are more solid work. It has to go in about an inch and you do have to force it.
  3. Wait 15 minutes
  4. Remove strip and start the sensor with the original code

The second method starts at 3:24

The next has been the more popular way so far. He shows you at the beginning of the above video but hers is more detailed and she also shows you how to apply Skin Tac and the overpatch. He shows you removing it from the sides and she shows removing it from the end.

  1. Let the sensor expire or stop sensor
  2. Remove the transmitter while the sensor stays on your arm,
    use a Contour test strip, hairclip, thin card or guitar pick I like a
    guitar pick the best. There is a clip on both sides slip the pick etc
    in between the sensor and the transmitter on both sides and the
    transmitter will pop up. .She explains how to pop it up from the end.
  3. Wait at least 15 minutes, longer is okay
  4. Snap the transmitter back into place
  5. Start the sensor using the original code

i have done the second method a few times and it works fine


For me it seems as though using the code makes the readings a little scattered, I wonder if anyone has tried codeless with daily calibration


@MarkP There are a few people that prefer using the no code method with daily calibrations. I think it’s because they were getting wonky readings. I have never tried it as calibrating a bunch of times in the first 24 hours ends up working for me. I can get mine to usually stay within 5 points that way.


That’s mostly how I do it now. The only exception is if I am putting it on right before I go to bed, and I don’t want to have to wake up to calibrate it 2 hours later.

For me, I think it is more accurate with calibrations.


@Marie Thanks for sharing this. I have not yet tried to restart a sensor but I may try this. How many more days do you get after restarting? And are the values pretty much stable and accurate? Thanks again!

I love restarts. At first I did it to build a back up supply. Mine are free through insurance. But I didn’t want to worry about being out. But a restart takes less calibrations at the beginning to get it accurate and it stays more reliable for me. Everybody’s time they get seems to vary, but most of mine seem to go around 26 days. One out of 3 or less it’s around 15 days. I had one that lasted 45 days!

I have to use Skin Tac to keep them on anyways, mine were starting to peel off originally within the first few days. And because of my starting longer swimming I added the over patch. So less work and less real estate to have to keep moving it to.

BTW I’m not sure if everyone has the same response, but a new sensor starts out too low for me and will stay too low unless I calibrate it. A restart will start out too high and slowly comes down but not enough. I usually calibrate fairly quickly because I can’t stand seeing the numbers off so much. In steps because otherwise it has a fit!


How often do you calibrate it after restarting? What has worked best?

Just like people can vary, so do the sensors. For me, some start off closer and then go haywire later and some start with huge differences.

I am usually restarting in the evening.

  1. Restarted sensors for me start high and I make an effort to make sure I am below 100 when they come on so my numbers aren’t absurdly high. So if it comes on under 130 I will leave it be until it starts to climb, and it will almost always climb for me. My first calibration I will pick a number in between what I’m at and the number it says. It will usually start to work it’s way down towards the number I calibrated into it.
  2. Then I will try to wait another couple of hours and I will still calibrate it about 10-15 points above what I am at, as it usually continues to drop. And I go to bed.
  3. The next morning I fine tune it and it might take one more fine tuning before I am happy. If it is 10 points off, I do still calibrate it. I always calibrate above my number by a few points as I’d rather they read higher and they have a tendency to trend down. But these things vary with sensors and people.

Things to remember when calibrating.

  1. Never calibrate with too much of a difference, it sends it into a repeated request cycle. You can stop repeated requested calibrations by entering the same number two times, one right after the other. Generally you try not to do this as it has an algorithm it follows so it will end up “off” later.
  2. Try to calibrate when your numbers are steady, Fast changing numbers will confuse it
  3. I always calibrate when I am at my preferred range which for me is between 95-105. Those are the numbers that I want it to be accurate at. I expect it to be more off at high numbers.

I have been using the second method, Last week I forgot to restart and more than an hour passed. When I did restart I had the best accuracy I have seen from the start.
Maybe that was a coincidence??


Wow! This worked for me. Usually after a restart it reads way high for 12 to 24 hours before suddenly behaving. Sometimes I don’t calibrate and sometimes I rage calibrate. But I tried this “middle” number with my restart today and it was reading accurately within 6 hours. Thanks for the tip!
