13.9.4 TRANSMITTER FAILED
This screen means that the transmitter is not
working. If you get this alert during a sensor
session, your sensor session automatically
stops. Contact Dexcom Technical Support (see
Chapter 15, User Assistance). Continue to check
your blood glucose value using your blood
glucose meter.
13.10 OUT OF RANGE/NO ANTENNA
PRECAUTION
Avoid separating the transmitter and receiver by more
than 20 feet. 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 result in
you missing severe hypoglycemia (low blood glucose) or
hyperglycemia (high blood glucose) events.
