What is Home Monitoring?
Dear Patient:
You have received a BIOTRONIK pacemaker
or implantable cardioverter-defibrillator
(ICD) with Home Monitoring function.
Home Monitoring pacemakers and ICDs are
additionally equipped with a special trans-
mitter. This transmitter automatically
transmits medical and technical information
to a mobile device, the CardioMessenger.
The CardioMessenger works like a cell
phone and automatically transmits the
information received from your device as
encoded messages to the BIOTRONIK
Service Center.
The transmission power from your device is
low so as to not impair your health in any
way. Since the transmission range is short,
the CardioMessenger is needed to send
the information to the BIOTRONIK Service
Center.
At the Service Center, the data are processed
and can be viewed only by your physician
on a secured Internet site in the form
of a comprehensive report called a
Cardio Report.
Your doctor can use this Cardio Report to
decide whether your device settings need
to be updated or if your therapy plan needs
to be changed. Thus, Home Monitoring
serves as a practical diagnostic aid.

How Do I Resolve Problems?
Problems with your CardioMessenger are
easy to identify, and they are ususally easy
to resolve.
Light 3
Yellow illumination – When this light is
continuously illuminated yellow, the Cardio-
Messenger was not able to end its self-test.
Solution – Reset the CardioMessenger.
If light 3 is still illuminated yellow, inform
your physician. You will find information
on a reset in “How Do I Reset the Cardio-
Messenger?” on page 34.
Yellow flashing – When this light continu-
ously flashes yellow, the CardioMessenger
cannot connect to the Service Center.
Solutions – Check if the charging station
is connected to the power supply and if
the cables from the charging station to
the telephone wall outlet are loose.
Check that the standard telephone line is
not dead, i.e., the CardioMessenger is not
blocked by other devices.
Check if you are able to dial toll-free
numbers with your telephone. If this is
generally not possible, have this service
set up for you by your telephone provider
or inform your physician.
Note: The CardioMessenger is designed to
operate with standard analog phone lines
providing Plain Old Telephone Service
(POTS). Compatibility with other phone
lines or services (e.g., Voice over IP (VoIP)
via analog or digital lines, cable TV phone
lines or ISDN) is not guaranteed. In these
cases compatibility testing at the patient’s
home is recommended. Proper set up of
CardioMessenger.book Page 32 Thursday, January 5, 2012 1:13 PM
33
the system at the patient’s home may
require installation of adapters and/or
analog phone lines. Please contact your
telephone service provider for information
on the type of phone line that you have.

so that the device can be checked and the
battery may be exchanged.
Note: If you take the CardioMessenger
out of the charging station, the battery
monitor light will go out to save energy.
Light 5
Off – If this light is off, proceed as follows:
Solutions – Check that the plugs of the
power cables are connected both to the
outlet in the wall and to the power supply.
Check that the green light of the power
supply is illuminated. If this is not the case,
either the power outlet is not being supplied
with electricity or the power supply is defec-
tive. Return a non-functioning power supply
to your physician.

a. Field strengths from fixed transmitters, such as base stations for radio (cellular(/cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the CardioMessenger is used exceeds the applicable RF compliance level above, the CardioMessenger
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the CardioMessenger.
b. Above the frequency range of 150 KHz to 80 MHz, ensure that field strengths are less than 3 V/m.

What is Home Monitoring?
Dear Patient:
You have received a BIOTRONIK pacemaker
or implantable cardioverter-defibrillator
(ICD) with Home Monitoring function.
Home Monitoring pacemakers and ICDs are
additionally equipped with a special trans-
mitter. This transmitter automatically
transmits medical and technical information
to a mobile device, the CardioMessenger.
The CardioMessenger works like a cell
phone and automatically transmits the
information received from your device as
encoded messages to the BIOTRONIK
Service Center.
The transmission power from your device is
low so as to not impair your health in any
way. Since the transmission range is short,
the CardioMessenger is needed to send
the information to the BIOTRONIK Service
Center.
At the Service Center, the data are processed
and can be viewed only by your physician
on a secured Internet site in the form
of a comprehensive report called a
Cardio Report.
Your doctor can use this Cardio Report to
decide whether your device settings need
to be updated or if your therapy plan needs
to be changed. Thus, Home Monitoring
serves as a practical diagnostic aid.

However, if the battery monitor light (light 4)
is off even though the CardioMessenger is
in the charging station, there might be a
problem.
Please refer to “How Do I Resolve Problems?”
on page 32 to find out how to resolve this
problem.
Note: In case the CardioMessenger has
been stored outside the operational
temperature, i.e., below 0°C (32°F) and
above 40°C (104°F), the batteries
discharge themselves much more quickly.
You should then first charge the Cardio-
Messenger before attempting to use it.
How Do I Turn Off the Charging Station?
The charging station can remain perma-
nently connected. This ensures that your
CardioMessenger will always start charging
as soon as you place it in the charging
station.

How Do I Resolve Problems?
Problems with your CardioMessenger are
easy to identify, and they are ususally easy
to resolve.
Light 3
Yellow illumination – When this light is
continuously illuminated yellow, the Cardio-
Messenger was not able to end its self-test.
Solution – Reset the CardioMessenger.
If light 3 is still illuminated yellow, inform
your physician. You will find information
on a reset in “How Do I Reset the Cardio-
Messenger?” on page 34.
Yellow flashing – When this light continu-
ously flashes yellow, the CardioMessenger
cannot connect to the Service Center.
Solutions – Check if the charging station
is connected to the power supply and if
the cables from the charging station to
the telephone wall outlet are loose.
Check that the standard telephone line is
not dead, i.e., the CardioMessenger is not
blocked by other devices.
Check if you are able to dial toll-free
numbers with your telephone. If this is
generally not possible, have this service
set up for you by your telephone provider
or inform your physician.
Note: The CardioMessenger is designed to
operate with standard analog phone lines
providing Plain Old Telephone Service
(POTS). Compatibility with other phone
lines or services (e.g., Voice over IP (VoIP)
via analog or digital lines, cable TV phone
lines or ISDN) is not guaranteed. In these
cases compatibility testing at the patient’s
home is recommended. Proper set up of
CardioMessenger.book Page 32 Thursday, January 5, 2012 1:13 PM
33
the system at the patient’s home may
require installation of adapters and/or
analog phone lines. Please contact your
telephone service provider for information
on the type of phone line that you have.
Light 4
Off – When this light is off even though the
CardioMessenger is in the charging station,
proceed as follows:
Solutions – Check if light 5 on the charging
station is illuminated. Is this not the case,
refer to the solutions described for light 5.
If light 5 is illuminated, check whether the
connecting parts on the CardioMessenger or
on the charging station are easily accessible
and not dirty.
If light 4 is still off, inform your physician
so that the device can be checked and the
battery may be exchanged.
Note: If you take the CardioMessenger
out of the charging station, the battery
monitor light will go out to save energy.
Light 5
Off – If this light is off, proceed as follows:
Solutions – Check that the plugs of the
power cables are connected both to the
outlet in the wall and to the power supply.
Check that the green light of the power
supply is illuminated. If this is not the case,
either the power outlet is not being supplied
with electricity or the power supply is defec-
tive. Return a non-functioning power supply
to your physician.

a. Field strengths from fixed transmitters, such as base stations for radio (cellular(/cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy.
To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured
field strength in the location in which the CardioMessenger is used exceeds the applicable RF compliance level above, the CardioMessenger
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the CardioMessenger.
b. Above the frequency range of 150 KHz to 80 MHz, ensure that field strengths are less than 3 V/m.
