Alteration of the Transmitter (CGM System) Procedure The transmitter's limited lifespan is approximately one year, requiring replacement after that period. Unfortunately, this new device can be unaffordable for many individuals with diabetes and their families. To extend the life of your CGM system, you have the ability to use it indefinitely through a modification process. However, exercise extreme caution when proceeding with this alteration! Warning: Before Proceeding * Check the transmitter's remaining battery charge. If it falls below 2 volts, do not attempt this procedure as it may cause damage to the transmitter's body. Alternative Batteries For optimal performance and safety, use CR2032 batteries instead of LiR2032. When charging these cells, a limiting element is necessary to reduce voltage and amperage to prevent swelling and internal battery damage.
