Explain the differences between the G6 4-digit code vs. the G7 4-digit code?

The Dexcom G7 sensor is factory calibrated. The 4-digit pairing code found on the G7 Wearable box and Applicator connects your G7 sensor to your smart device or receiver through bluetooth.
The Dexcom G6 sensor has two modes:
  • Factory calibration: Enter the 4-digit sensor code found on the G6 sensor you are applying. This provides the highest level of accuracy without the need to enter BG readings.
  • Manual calibration: Don’t enter the 4-digit sensor code. You’ll be prompted to enter BG meter values after the 2-hour warm up, then every 12 hours of the first sensor day and then once a day for the remaining nine days of the sensor session.
