it reconnects with the cell phone monitor.
Page 17
Caution
If the sensor (ACT I firmware version 0.1g
and ACT III firmware version 1.0.4) is not
connected to the cell phone monitor (via
Bluetooth) for more than 2 hours (ACT I) or 6
hours (ACT III) and the sensor's battery is
replaced, the sensor (on reconnection) will
start with new data and not download the
data stored, thus overriding the data stored
when it was not connected.
Electrode disconnection might cause a faulty
ECG analysis and/or false events due to
noise created by the electrode
disconnection.
The impedance test (occurring every two
minutes) overrides ECG recording, which
means the ECG will lack 1 second (ACT I) or
0.5 second (ACT III) of recording every two
minutes.
Do not turn the cell phone monitor sound off
or reduce the volume so that it is inaudible.
After exiting the ACT (monitor) application, it
will take up to 3 minutes for all the processes
to end. This means you must wait 3 minutes

2. General Description
The ACT is an automatically activated cardiac monitoring
system that requires no patient intervention to capture or
transmit an arrhythmia when it occurs. When an arrhythmia is
detected, the ACT monitoring system utilizes an integrated cell
phone monitor to transmit the data to the Monitoring Center for
analysis.
Sensor
The sensor records and transmits the data to the cell phone
monitor. It can hold up to 6 hours (ACT III) or 2 hours (ACT I) of
data in its memory. This means that if a patient is away from the
cell phone monitor and wearing the sensor, the data is still being
recorded. Once the patient is in range (within 30 feet /10
meters) of the cell phone monitor, the data will be transmitted.
Cell Phone Monitor
The cell phone monitor receives ECG data from the sensor via
Bluetooth and can store up to 30 days of data. The cell phone
monitor has a special application that converts the raw ECG
data and sends it using a cellular network to the monitoring
center for interpretation or, in the case of no cellular coverage,
data can be sent using a landline and a modem. The cell phone
monitor should be carried in the supplied pouch whenever
possible.
Batteries
The sensor batteries are special batteries. DO NOT use over
the counter AA batteries. DO NOT dispose of the batteries –
they should be returned to LifeWatch when your monitoring
session is completed.
Page 26
About Bluetooth
Bluetooth is a wireless technology that enables the sensor and
cell phone monitor to communicate with each other. The ACT
system uses Bluetooth technology to transmit ECG data from
the sensor to the cell phone monitor. The cell phone monitor
internal Bluetooth component is on and running continuously
(24 hours a day) for the entire monitoring period; therefore, the
cell phone monitor must be ON at all times. Bluetooth operates
like a radio and is susceptible to interference. If the sensor and
cell phone monitor are more than 30 feet (10 meter) apart and a
Bluetooth connection cannot be made, no data loss will occur as
long as the sensor and cell phone monitor are reconnected
within 6 hours (ACT III) or 2 hours (ACT I). When the sensor
and cell phone monitor are within 30 feet (10 meter) of one
another, the Bluetooth will automatically re-connect. Charge the
phone every night for the whole night and whenever possible
throughout the day.
For optimal system performance, the recommended distances
between the cell phone monitor and sensor during the
monitoring period should be as follows:
Normal operation - within 20 inches (50 cm).
During cell phone monitor charging - within10 feet (3
meter)
Page 27
Note
The cell phone monitor automatically transmits the
detected ECG events to the monitoring center and the
user has the ability to send manually recorded events.
The data is saved on the storage card and the event
data is deleted after a successful transmission to the
monitoring center.
3. System Description
The ACT Continuous ECG Monitor and Arrhythmia Detector is
designed for self-testing by patients at home and for analysis by
trained technicians at a remote Monitoring Center.
The sensor is used for the acquisition and transmission of the ECG
signal. The sensor is equipped with three (ACT I) or four (ACT III)
electrodes on a harness and works in conjunction with a cell phone
monitor.
The sensor houses a 3.6V AA lithium-thionyl chloride battery, an ECG
channel circuit, an impedance measurement circuit, a pacemaker
detection circuit, a flash buffer memory, a Bluetooth transceiver and a
buzzer. The ECG signals are received, filtered and amplified in the
input circuit, stored in the flash memory buffer and transmitted via
Bluetooth to a cell phone monitor. The cell phone monitor runs a
proprietary application that is configured to process and transmit the
ECG recordings via a cellular network while storing them and the
detected physiological events on a micro-SD memory card. When a
physiological event is detected, the cell phone monitor transmits the
recorded ECG automatically via cellular link, to a Monitoring Center
for professional analysis. If the patient is out of the cellular network
coverage area, the cell phone monitor will send all events that were
stored when the cellular link is re-established. The cell phone monitor
can also transmit ECG alarms via landline telephone with an
additional POTS Bluetooth modem.
The sensor loops up to 2 hours (ACT I) or 6 hours (ACT III) cyclic
buffer of ECG data in the internal flash memory in order to preserve
the ECG in cases when the Bluetooth connection to the cell phone
monitor is down.

Using Your Phone Near Other Electronic Devices
Most modern electronic equipment is shielded from radio frequency
(RF) signals.
However, certain electronic equipment may not be shielded against
the RF signals from your wireless phone. Consult the manufacturer to
discuss alternatives.
Implantable Medical Devices
A minimum separation of six (6) inches (15 cm) should be maintained
between a handheld wireless phone and an implantable medical
device, such as a pacemaker, to avoid potential interference with the
device.
Persons who have such devices:
• Should ALWAYS keep the phone more than six (6) inches (15 cm)
from their implantable medical device when the phone is turned ON;
• Should not carry the phone in a breast pocket;
• Should use the ear opposite the implantable medical device to
minimize the potential for interference;
• Should turn the phone OFF immediately if there is any reason to
suspect that interference is taking place.
• Should read and follow the directions from the manufacturer of your
implantable medical device. If you have any questions about using
your wireless phone with such a device, consult your health care
provider.
Hearing Aid Compatibility with Mobile Phones
FCC Hearing-Aid Compatibility (HAC) Regulations for Wireless
Devices
On July 10, 2003, the U.S. Federal Communications Commission
(FCC) Report and Order in WT Docket 01-309 modified the exception
Page 90
of wireless phones under the Hearing Aid Compatibility Act of 1988
(HAC Act) to require digital wireless phones be compatible with
hearing-aids. The intent of the HAC Act is to ensure reasonable
access to telecommunications services for persons with hearing
disabilities.
While some wireless phones are used near some hearing devices
(hearing aids and cochlear implants), users may detect a buzzing,
humming, or whining noise. Some hearing devices are more immune
than others to this interference noise, and phones also vary in the
amount of interference they generate.
The wireless telephone industry has developed a rating system for
wireless phones, to assist hearing device users find phones that may
be compatible with their hearing devices. Not all phones have been
rated. Phones that are rated have the rating on their box or a label
located on the box.
The ratings are not guarantees. Results will vary depending on the
user’s hearing device and hearing loss. If your hearing device
happens to be vulnerable to interference, you may not be able to use
a rated phone successfully. Trying out the phone with your hearing
device is the best way to evaluate it for your personal needs.
M-Ratings: Phones rated M3 or M4 meet FCC requirements and are
likely to generate less interference to hearing devices than phones
that are not labeled. M4 is the better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC requirements and are
likely to be more usable with a hearing aid’s telecoil than phones that
are not rated. T4 is the better/higher of the two ratings.
Hearing devices may also be rated. Your hearing device manufacturer
or hearing health professional may help you find this rating. Higher
ratings mean that the hearing device is relatively immune to
interference noise. The hearing aid and wireless phone rating values
are then added together. A sum of 5 is considered acceptable for
normal use. A sum of 6 is considered for best use.
In the above example, if a hearing aid meets the M2 level rating and
the wireless phone meets the M3 level rating, the sum of the two
values equal M5. This should provide the hearing aid user with
“normal usage” while using their hearing aid with the particular
Page 91
wireless phone. “Normal usage” in this context is defined as a signal
quality that is acceptable for normal operation.
The M mark is intended to be synonymous with the U mark. The T
mark is intended to be synonymous with the UT mark. The M and T
marks are recommended by the Alliance for Telecommunications
Industries Solutions (ATIS). The U and UT marks are referenced in
Section 20.19 of the FCC Rules. The HAC rating and measurement
procedure are described in the American National Standards Institute
(ANSI) C63.19 standard.
Some digital wireless phones may interfere with some hearing aids. In
the event of such interference, you may wish to consult your hearing
aid manufacturer to discuss alternatives.
Other Medical Devices
If you use any other personal medical devices, consult the
manufacturer of your device to determine if it is adequately shielded
from external RF energy. Your physician may be able to assist you in
obtaining this information. Switch your phone off in health care
facilities when any regulations posted in these areas instruct you to do
so. Hospitals or health care facilities may be using equipment that
could be sensitive to external RF energy.
Children Using Wireless Phones
The scientific evidence does not show a danger to users of wireless
phones, including children and teenagers. If you want to take steps to
lower exposure to radio frequency energy (RF), the measures
described above would apply to children and teenagers using wireless
phones. Reducing the time of wireless phone use and increasing the
distance between the user and the RF source will reduce RF
exposure.
Some groups sponsored by other national governments have advised
that children be discouraged from using wireless phones at all. For
example, the government in the United Kingdom distributed leaflets
containing such a recommendation in December 2000. They noted
Page 92
that no evidence exists that using a wireless phone causes brain
tumors or other ill effects. Their recommendation to limit wireless
phone use by children was strictly precautionary; it was not based on
scientific evidence that any health hazard exists.
Body-worn Operation
To comply with RF exposure requirements, a minimum separation
distance of 0.50 inch (1.5 cm) must be maintained between the user’s
body and the handset, including the antenna. Third-party belt-clips,
holsters, and similar accessories used by this device should not
contain any metallic components. Body-worn accessories that do not
meet these requirements may not comply with RF exposure
requirements and should be avoided.
Use only the supplied or an approved antenna. Unauthorized
antennas, modifications, or attachments could impair call quality,
damage the phone, or result in violation of regulations. Do not use the
phone with a damaged antenna. If a damaged antenna comes into
contact with the skin, a minor burn may result. Please contact your
local dealer for replacement antenna.
