Dexcom G6 is a popular continuous glucose monitoring (CGM) system that helps individuals with diabetes manage their blood glucose levels more effectively. Dexcom G6 uses a transmitter to send real-time glucose readings from the sensor to a compatible display device or an optional G6 receiver via Bluetooth. In this blog post, we will answer some common questions about the Dexcom G6 transmitter including its life expectancy, when to replace it, and the process of activating a new transmitter.

 

Dexcom G6 transmitter life-expectancy

The Dexcom G6 transmitter has a life-expectancy for up to 90 days, or 3 months, from when it was activated. The transmitter also has a use by date that is listed on the box. Dexcom users should start using that transmitter before that date. After the use by date, the transmitter may no longer function accurately.

 

Can a Dexcom G6 transmitter last longer than 90 days?

According to reports from the diabetes community, some users have experienced the Dexcom G6 transmitter lasting for 110-112 days, which surpasses the 90-day warranty period provided by Dexcom.

How do I know when my Dexcom transmitter expires?

If you haven't received the final 10-day warning indicating the remaining battery life, you have the option to reuse the transmitter for your next session. Starting three weeks before the end of its battery life, the warnings will count down until there are only 10 days, equivalent to one sensor session, left. However, if the transmitter battery has less than 10 days remaining, you won't be able to initiate a new session and instead, you will see the message "Pair New Transmitter."

How do I check my Dexcom transmitter’s battery life?

You can locate the activation date of your transmitter on your display device. If you are using a receiver device, go to Menu > Settings > Transmitter > Transmitter Info. If you are using the Dexcom app, go to Settings > Transmitter. This will provide you with the date the transmitter was activated on.

 

If your transmitter has exceeded the 90 days since activation and is no longer functioning, it is necessary for you to replace the device with a new transmitter. However, if your transmitter is still within the 90-day period from activation and you are experiencing connectivity issues, you can contact Dexcom customer support for further assistance.

What to do when your Dexcom transmitter expires?

When the battery of your Dexcom G6 transmitter reaches its expiration, you will be notified with an alert on your display device. It is advised for Dexcom users to continue using their current transmitter until they receive a specific message instructing them to pair a new transmitter. After receiving the “Replace Sensor & Transmitter Now” or “Pair New Transmitter” notification, follow the prompts displayed on your device in the specified order. If you get stuck, refer to Dexcom's website for instructions.

 

Will Dexcom replace a transmitter?

Dexcom G6 transmitters are covered under a limited warranty for the first 90 days after activation as long as users activate the transmitter within 5 months of the shipping date. If your transmitter fails or malfunctions during the warranty period, Dexcom will typically replace the transmitter free of charge. Contact Dexcom customer support to request a replacement.

How do you know when to replace the Dexcom transmitter?

The Dexcom G6 transmitter is designed to last for approximately 90 days. Dexcom will send automated reminders at 3 weeks, 2 weeks and the final sensor insertion to ensure you have sufficient time to reorder a new one and avoid any interruption in receiving your glucose readings.

If you’re curious about when your transmitter will expire, you can check the Dexcom App or Display Device by going to Settings > Transmitter > Activated On Date. This will allow you to see when you activated your transmitter and determine if the expiration date is approaching.

How to activate a new Dexcom G6 transmitter

Activating a new Dexcom G6 transmitter is a straightforward process. Here are the general steps to follow:

  1. Click on the “Pair New” prompt on your Display device.
  2. Follow the on-screen instructions for pairing a new sensor and transmitter

 

Contact Dexcom customer support if you need assistance pairing a new transmitter.

How to get a replacement Dexcom G6 transmitter

If your Dexcom CGM is expiring soon and you need to order a replacement, you must first contact the supplier or distributor from whom you originally obtained your Dexcom from. You will need to contact their customer support team either by phone or through their website to explain that your CGM transmitter is about to expire and request a replacement order. You may need to provide them with personal information, including your contact information, shipping address, billing information, and health insurance information.

 

Once your eligibility for a replacement is confirmed, the supplier will then ship a new transmitter to your designated shipping address, or you can pick it up from a local pharmacy. Upon receiving your new replacement, carefully follow the instructions on your display device for inserting a new sensor and transmitter.

 

In conclusion, being aware of the lifespan of the Dexcom G6 transmitter allows users to proactively plan for replacements and maintain uninterrupted glucose monitoring. By staying informed and prepared, individuals can ensure a seamless and accurate monitoring experience with their Dexcom G6 device.
