Unfortunately, the transmitter PIN is required to activate and use your BUZUD CGM system. If you have lost your PIN, you will need to use a new sensor and transmitter set that comes with a valid PIN.

Do not use a PIN from another device or try to guess or make one up. Doing so may lead to inaccurate readings and improper functioning of the CGM system.

To avoid this issue in the future, we recommend:

• Keeping the transmitter PIN noted safely before installation
• Not discarding the packaging until the device is fully set up
