What is the maximum distance between Sensor and Reader in order to receive the alarms?

For you to receive alarms, they must be turned ON, and you should ensure that your Reader is always within 6 meters (20 feet) of you. The transmission range is 6 meters (20 ft) unobstructed. If you are out of range, you may not receive glucose alarms.
