One possible reason is that the sensor may be under pressure while you're sleeping, which can cause the BUZUD CGM to report lower glucose readings. Once the pressure is relieved, the readings usually return to values that are closer to your fingerstick results.To avoid this issue, choose a sensor site that is less likely to be bumped, compressed, or laid on during sleep.If the readings do not return to normal after relieving the pressure, consider doing a calibration when your blood glucose trend is stable to help the system regain accuracy.
The BUZUD CGM transmitter is rated IP68 water resistant, meaning it can withstand immersion in up to 1 meter of water for up to 30 minutes. This makes it safe for daily activities like showering or brief rinsing.However, please keep the following in mind:Bathing or prolonged swimming is not recommended, as it may exceed the device's waterproof specifications.While the transmitter is water resistant, your smartphone or display device should be kept in a dry area to avoid damage.If you're in the water (e.g., swimming), make sure your display device remains within 6 meters (approx. 20 feet) of the transmitter to continue receiving glucose readings.
What Should I Do If the BUZUD CGM Applicator Won't Come Off?If the BUZUD CGM applicator gets stuck during use, don’t panic. Follow these steps to safely remove both the applicator and the sensor:Gently peel off the adhesive patch with the applicator still attached.Check the insertion site to ensure that the sensor has been fully removed and nothing is left in the skin.Do not reuse the applicator — it is designed for single use only.If you experience any issues, please contact BUZUD customer support or consult a healthcare professional.
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 installationNot discarding the packaging until the device is fully set upIf you need further help, please contact BUZUD customer support for assistance.

BUZUD CGM sensors are designed with medical-grade adhesive patches to help them stay firmly attached to your skin throughout the wear period. However, due to differences in skin type, moisture, and daily activities, the patch may begin to peel off early. With proper preparation and care, you can help your sensor remain secure for the full wear time (e.g., 14 or 15 days).Before Sensor InsertionTimingAfter insertion, the adhesive needs time to bond with your skin. During this period, avoid sweating, bathing, or swimming.If inserting the sensor before bed, make sure the warm-up period is complete before sleeping.PlacementAvoid areas with frequent bending, friction, body hair, or near the waistband.Rotate insertion sites with each new sensor session to reduce skin irritation.Skin PreparationEnsure the insertion area is flat, clean, and completely dry.If using adhesive supplements, avoid the needle insertion point and only apply around the edge. Let it dry fully before insertion.Cleaning tips:Remove leftover adhesive from previous sensors.Use adhesive remover if needed.Wash the site with soap and water, let it dry, then scrub with an alcohol wipe and let dry again.Other TipsWait 10–15 minutes before inserting a new sensor after removing the previous one.Store sensors in a dry place (2°C to 25°C).During Sensor Insertion (for BUZUD Applicator)1. Twist Off the CapGently twist and remove the top cap of the applicator to expose the adhesive patch and sensor.2. Press and HoldOnce the applicator is placed on the skin, press down firmly around the patch for 30–60 seconds to help it stick well.3. Insert the SensorPress the button to insert the sensor. Then gently remove the applicator from the skin.After Insertion: Reinforce and MaintainRub the PatchImmediately after insertion, rub around the entire patch three times using your fingers or fingernail. This improves adhesion and smooths out wrinkles.Overpatch or Medical TapeIf you have oily or sweaty skin, apply an overpatch or medical tape immediately after sensor insertion.For drier or more sensitive skin, you can wait and observe whether the patch begins to lift before applying any reinforcement.Following these steps can help ensure that your BUZUD CGM sensor stays in place and performs reliably for its full wear duration.
