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.
