2-hour startup, review the following troubleshooting tips:

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 the receiver (see Chapter 5, Section 5.2, The Settings

Support (see Chapter 15, User Assistance).
At the end of the 2-hour startup period the receiver lets you know it
is time to calibrate the sensor. Chapter 7, Calibrating the Dexcom G4
PLATINUM Professional System, tells you how to calibrate the sensor.

the patch is peeling up, you can use medical tape (such as Blenderm

,
Tegaderm
™
, Smith & Nephew IV3000
®
, 3M
™
tape) for extra support.
If you use tape, only tape over the white adhesive patch on all sides
