9.7 BATTERY AND CHARGER TROUBLESHOOTING
Only use the Dexcom cable and battery charger to charge your receiver.
1. Remember to charge your receiver battery as needed. The charge will last
approximately 3 days, depending on how often you turn on your receiver, use
the alerts, and enter events.
2. If your receiver does not show the charging icon when plugged into the
charger make sure that both ends of the USB cable are fully inserted into the
receiver port and wall charger.
3. If your battery drains and is not charged for a few weeks it may not turn on.
If your receiver does not turn on, rst try to charge it (see Chapter 1, Section
1.4, Charging Your Receiver Battery). If your receiver still does not turn on you
may need to reset the receiver (connect the receiver to the charger before
resetting):
a. Insert the end of a paperclip into the small circular hole on the back of the
receiver and push down. The receiver will vibrate and show the processing
screen.
b. You will now need to charge your receiver, and the time and date may need
to be reset (see Chapter 1, Section 1.4, Charging Your Receiver Battery
and Chapter 2, Section 2.2, The Settings Menu).
