01

Before You Buy

What is the KS3 CKM System and who should use it?

The KS3 Continuous Ketone Monitoring (CKM) System is designed to measure ketone levels in the interstitial fluid of adults aged 18 and older. It helps users track ketone trends in real time using a wearable sensor and mobile app. This system is not intended for diagnosing, treating, or monitoring medical conditions, and should not be used by individuals with extensive skin issues or implanted medical devices.

How does the system work and what are its main components?

The system includes a disposable electrochemical sensor, a sensor applicator, and the SiBio CKM mobile app. Once the sensor is applied to the skin, it continuously measures ketone levels and transmits data via Bluetooth to the app, updating every 5 minutes. The system provides ketone trend graphs and historical data views to help users track changes over time.

Is this system suitable for children or medical treatment?

No. The KS3 CKM System is only for individuals aged 18 and older and should not be used for medical decisions or disease management.

How can I make sure I am purchasing an authentic SiBio CKM device and not from a counterfeit site?

To ensure you are purchasing a genuine SiBio CKM device, always buy directly from our official website or from authorized retailers listed on our website. Be cautious of websites with URLs that look similar to ours, unusually low prices, unusual payment methods, or unclear contact information. If you suspect a site may be selling counterfeit SiBio products, please report it to us at support@sibiosensor.com.

Does the sensor interfere with pacemakers?

The sensor has not been evaluated for use with implanted medical devices. Use is not recommended.

02

Getting Started

Where and how should I apply the sensor for best results?

Apply the sensor only to the back of your upper arm, avoiding areas with scars, tattoos, moles, stretch marks, or skin folds. Choose a flat area that does not bend during daily activities. Always rotate application sites between uses to avoid skin irritation. Before applying, clean the area with soap and water, dry it, then wipe with alcohol. Ensure the skin is completely dry before proceeding.

Can the sensor be reused, and what should I do if the packaging is damaged?

No. Each sensor is single-use and cannot be sterilized or reused. If the sterile package is damaged or opened, do not use the sensor. Contact customer support for assistance.

What should I expect during the application? Is it painful?

Applying the sensor may cause minor bruising or light bleeding, especially if small blood vessels are contacted. This is typically not harmful. If bleeding is persistent, remove the sensor and consult a healthcare provider. Apply pressure gently with a cotton swab if needed.

How do I start a new sensor after applying it?

Use the SiBio CKM App to pair and activate the sensor. You can do this by scanning the 2D code on the sensor box or manually entering the 6-digit pairing code. If your phone supports NFC, tap it to the sensor to pair. Only one sensor can be paired at a time.

Why is there a 60-minute warm-up period after activation?

The sensor’s sensing tip is covered by a membrane that needs time to equilibrate with your body’s interstitial fluid. This ensures the ketone readings are accurate and stable. During this period, no ketone data will be displayed.

What should I do if pairing fails or the app cannot detect the sensor?

First, ensure Bluetooth is turned on and your phone is within 10 meters of the sensor with no major obstacles. If pairing still fails, restart the app and try again. If the issue persists, contact support.

03

Using Your Sensor

How long can I wear the sensor and what might affect its lifespan?

Each sensor is designed to last up to 14 days. However, heavy sweating, intense exercise, or improper skin preparation can cause the sensor to loosen prematurely. If the sensor becomes detached or the tip comes out of the skin, discard it and apply a new one.

Is the sensor waterproof, and what activities are allowed?

Yes. The sensor has an IP38 water resistance rating, meaning it can be submerged up to 1 meter for up to 1 hour. You can wear it while showering or swimming but avoid direct high-pressure water and prolonged submersion.

Can I continue normal physical activities with the sensor?

Yes, the sensor is designed to remain functional during regular daily activities and light to moderate exercise.

Is it okay to sleep on the side where the sensor is applied?

Yes, but avoid continuous pressure or friction. Make sure tight clothing or bedding does not rub the sensor.

What should I do if the sensor does not stick properly?

Clean the site thoroughly, avoid lotions, and consider shaving the area. If it continues to come loose, remove it and apply a new one to a different arm.

What if I experience skin irritation or allergic reactions?

Irritation can be caused by pressure from clothing or sensitivity to the adhesive. Remove the sensor and consult a healthcare professional. Do not reuse the same site repeatedly.

Is the sensor suitable for air travel?

Yes. However, remove it before undergoing security procedures involving strong electromagnetic fields such as MRI, CT, or X-rays.

What should I do before medical scans like MRI or CT?

Always remove the sensor before any procedures involving strong magnetic or electromagnetic fields. Apply a new sensor after your appointment.

How should I store unused sensors and applicators?

Store at temperatures between 2°C and 30°C and humidity between 10% and 93%. Avoid freezing or leaving sensors in hot environments like parked cars.

Can I refrigerate the sensor?

Yes, as long as it remains within the approved temperature range. Do not store it in the freezer.

How do I dispose of used sensors and applicators?
