PRECAUTION
The transmission range from the transmitter to the receiver is up to 20 feet without
obstruction. Wireless communication does not work well through water so the range is
much less if you are in a pool, bathtub, or on a water bed, etc. Types of obstruction
differ and have not been tested. If your transmitter and receiver are farther than 20 feet
apart or are separated by an obstruction, they might not communicate or the
communication distance may be shorter and you might miss a low or high blood
glucose value.
