6.8 SENSOR STARTUP PERIOD
The sensor needs a 2-hour startup period to adjust to being under
the skin.
Your trend graph shows a 2-hour countdown
symbol in the upper right corner.
1. Press SELECT during the startup period
to turn the on receiver display and see
this symbol.

glucose readings, alerts and alarm during
the countdown.
If you see the out of range symbol at the top of the screen during the
2-hour startup, review the following troubleshooting tips:
• Make sure your receiver and transmitter are within 20 feet of each
other without obstruction. Check in 10 minutes to see if the antenna
symbol shows in the upper left corner of the receiver screen.
• If the receiver and transmitter are still not communicating, check
the device information screen to make sure the correct transmitter
ID is entered into your receiver (see Chapter 5, Section 5.2, The
Settings Menu).
• If the correct transmitter ID is in your receiver and the receiver and
transmitter are still not communicating, contact Dexcom Technical
Support (see Chapter 15, User Assistance).
At the end of the 2-hour startup period the receiver lets you know it is
