Included with your BSXinsight is a custom calf compression sleeve. Place the fully charged BSXinsight sensor into the sleeve pocket through the larger inside opening. Carefully pull the sleeve up to just below the bend in your knee as shown in the picture below. The sleeve should fit comfortably yet securely to the leg, centered directly over the widest portion of your calf. This is a very important step!
For daily activities, if you want to wear it on another muscle, just turn the sleeve inside out and put your BSXinsight in the pocket, like normal. Lay it flat over the muscle and wrap it in place with a bandage.
