BIOTRONIK CardioMessenger Smart Manuel Technique page 22

The CardioMessenger restarts and performs the self-
test. It checks the connection to the cellular phone
network. The operation and battery icon is displayed once
the connection test is completed successfully. The
CardioMessenger is now ready for use.
The connection test can take up to 15 minutes.
If the CardioMessenger is generally unable to connect to
the cellular phone network from near your bed, contact
your physician.
Note: Missing cellular phone network connection can
occur in rooms with thick walls or when travelling.
