Changing the Sensor and Adhesive Tape


The kit contains two sensors, each of which is designed for four days of continuous wear. The kit also contains 12 extra adhesive tapes, which should be replaced if they get dirty or if the adhesive is no longer sticking.

When inserted into a sensor, the indicator light on the chip will show you if the sensor needs to be replaced:
