Out Of Range/No Antenna; Alerts Are Not Working - Dexcom G4 PLATINUM User Manual

13.10 OUT OF RANGE/NO ANTENNA

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.
This screen means your receiver and transmitter are not communicating and you are not getting sensor
glucose readings.
• Your receiver and transmitter only communicate when you are in an active sensor session.
• Each time you start a new sensor session, wait 10 minutes for your receiver and transmitter to start
communicating.
• You may sometimes experience loss of communication for 10 minutes at a time. This is normal.
• If you see the out of range symbol in the status area for more than 10 minutes, move your receiver
and transmitter within 20 feet of each other without obstruction. Wait 10 minutes and communication
should be restored.
• You must enter your transmitter ID correctly into your receiver to receive sensor glucose readings (see
Chapter 5, Section 5.2, The Settings Menu). Make sure you have removed your sensor and stopped your
sensor session before checking or changing your transmitter ID. "Transmitter ID" will not appear as an
option on the Settings menu during a sensor session.
If you are still having trouble getting system readings, contact Dexcom Technical Support (see Chapter
15, User Assistance).
