Call Back Function
The call back function is an additional function that your physician can use in different ways. You will be
informed by your physician if and how he or she will use this function.
For example, your physician can use the call back icon to ask you for a call. Your physician can turn on
the icon via the cellular phone network. It will then flash for a maximum of three days.
Contact your physician during office hours as soon as you notice that the call back icon is flashing.
Attention
Check once a day whether your CardioMessenger is switched on and ready for use.
Turning off the call back icon
To turn off the call back icon, briefly turn off the CardioMessenger.
1. Press the blue key on the right side of the CardioMessenger for about two seconds.
2. All symbols disappear.
3. Wait approximately thirty seconds.
4. Press the blue key again for approximately two seconds.
5. The CardioMessenger performs a self-test.
6. The operation and battery icon is then displayed, and the call back icon stops flashing.
However, please do not forget to call your physician.
If the CardioMessenger is connected to the power supply brick, it starts automatically. You neither have
to wait nor switch it on.
