1.3 USAGE RESTRICTIONS AND SAFETY PRECAUTIONS
In order to guarantee the patient’s and the user’s safety as well as a correct
working of the equipment, it is necessary to operate within the consented
restrictions and adopt all the precautions listed below:
ATTENTION
Prior to usage, verify that all the safety requirements are satisfied.
The equipment must not be supplied by or connected to other instruments until
such safety conditions are restored.
1.3.1 ELECTRIC SAFETY
Leakage current
The maximum patient leakage current from the equipment, measured according to
the IEC 60601-1 standard (for Type BF) is less than 100 A.
However take care when using the equipment at the same time with other
instruments. In the event the patient is connected to several instruments at the
same time, it is necessary to remember that the sum of the leakage currents
determined by each instrument may exceed this value.
Patient Connection
All patient connections to the equipment are through the device using the proper
adhesive electrode patch provided. Any patient electrodes connected to the device
by any other means may constitute an unsafe condition that could result in injury
or death to the patient.
ATTENTION
All patient connections on the device are isolated from AC power ground.
Do NOT join these connections to earth ground or AC power ground since such an
action constitute an unsafe condition that could result in serious injury or
accidental death to the patient.
ATTENTION
The electrode through which the signal is captured from the body of the patient are
not part of the amplifier system, in any case it is MANDATORY to use only
electrode or sensor approved for commercial use by FDA (USA) or/and CE marked
(93/42 EEC directive and following amendment 2007/47/EC).

To ensure the safety of the patient and the operator, please follow all the warnings
and caution listed in this manual.
Connect to the equipment the proper specified power supply only. In order
to guarantee the electrical safety requirements, the recharge of internal battery
pack of equipment, must be performed by means the proper medical AC/DC
adapter only. The power supply is supplied by PREVENTICE with the
equipment. The allowed models are:
Trademark FRIWO, Model FW7662M/06
To recharge the equipment place it on the Charging Cradle according to the
appropriate orientation (only one is possible due to the mechanical constraints)
and only after this operation connect the Charging Cradle to the AC/DC Power
supply and this last to the mains.
After the recharging operation is complete disconnect the AC/DC Power
supply from the mains and only after this operation remove the equipment from
the Charging Cradle.
Take care when using the equipment at the same time with other
instruments. In the event the patient is connected to several instruments at the
same time, it is necessary to remember that the sum of the leakage currents
determined by each instrument may endanger his life.
Take care when using the equipment at the same time with other radio-
frequency instruments. In the event the equipment is used in a surgery room
at the same time with a radio knife (Radio-Frequency instrument = RF), it is
necessary to hold the radio knife point as far as possible from the electrodes, in
order to reduce as much as possible the risk of RF currents making on such
electrodes and the consequent burns. Therefore it is necessary to use electrodes
with a larger surface contacting the patient body, in order to limit the RF
current density to acceptable values. In case it is not possible to use the proper
electrodes, it is recommended to disconnect the patient from the equipment
before using radio-frequency instruments.
The equipment is not protected against the defibrillator discharges. Please
remember that the equipment is not protected against the defibrillator
discharges; for this reason, in the event it should be necessary to use the
defibrillator, it is necessary to disconnect the patient from the equipment in
order to avoid the patient being burned in the electrode contact areas and the
equipment undergoing sever and irreversible damages.
Avoid contact of patient and electrodes with conductive metal items. When
the equipment is connected to other instruments supplied by the mains, the
whole input circuit to which the patient is connected is electrically isolated
(floating isolation). It is necessary to avoid the patient and any conductive part
connected to the patient (electrodes, connectors, and transducers) coming into
contact with conductive parts (ground included). Please observe this precaution
to avoid compromising the equipment isolation level. This precaution must be
observed in order to avoid that accessible metal parts of the device get in touch
![](/img.php?id=1733250&img=bg9.png)
BODYGUARDIAN CONTROL UNIT – BASE KIT Operator Manual

`
with external conductive parts thus damaging the isolation level of the
equipment.
Do not connect additional Multiple Portable Socket-Outlet or extension
cord. Multiple portable socket-outlet or extension cord shall not be connected
to the system.
Observe the IEC 60601-1-1 and the IEC 60601-1-2 standards in case of
connection with other instruments. The connection of the equipment with
other devices is allowed only when the safety requirements for the patient, the
user and the environment are not compromised. If the Manual does not contain
enough information about the possibility of interconnection with other devices,
the user should contact the manufacturer or the nearest authorized servicing
center to have information about the effects that coupling devices may have on
the patient, the user and the environment.
Replace damaged parts immediately. Cables, connectors, accessories, or
other parts of the equipment must be replaced immediately when damaged or
not working correctly. In these cases, contact the nearest authorized servicing
center.
Do not connect items (accessories and peripherals) which are not specified
as part of the system expressley indicated by PREVENTICE. In order to
guarantee all the safety requirements, it is necessary to use only the accessories
and peripherals specified in this Manual as part of the system, which have been
tested with the equipment. The usage of accessories and consumer goods
supplied by other manufacturers or not specifically indicated by
PREVENTICE does not guarantee the safety and the correct working of the
equipment. Use only peripherals in compliance with the standards of the class
they belong to.
Check the functionality of the system before starting any recording. It is
strongly recommended to check the overall functionality of the system before
starting any recording. In case any anomalies or malfunctioning should be
noticed, immediately disconnect the patient from the system (if a patient is
already connected), switch off the system and ask for service to qualified
personnel. In particular (for example) if, with a patient connected to the
system, some anomalous tracing, like isoelectric or greatly artefacted signal,
should be noticed on the monitor during recording: in this case if the problem
should not be solved with the assembly standard technique (poor electrode
connection, broken lead etc) immediately acts as above, disconnect the patient,
do not use the system and ask for servicing.
Periodically check that all the system works regularly during “long term
recording”. During “long term recording” (more than one hour) it is strongly
recommended to periodically check that all the system works regularly without
any sign of malfunctioning. If any anomalies or flat traces should be noted act
as in the previous warning. In particular any electrode site used for long term
must be checked for irritation and redness. Check each electrode periodically to

evaluate the skin condition under the electrode. Redness, blistering and
permanent skin scarring can occur if electrodes are not regularly monitored.
Using the equipment on patients with a heart pace-maker is not allowed. It
is not allowed using the equipment in the case of patients with implanted
electric devices (or bed partners with implantable devices), especially heart
pace-makers, because the equipment may cause the cardiac stimulator
malfunctions. Patients with cardiac pacemakers should not undergo any
examination with this equipment without authorization and under the severe
control of a specialized physician. For the same reason it is also necessary to be
careful when using the equipment in proximity of operators or persons with
implanted electric devices

1.9 INFORMATION ABOUT RECYCLING OF MATERIALS
In accordance with the specific worldwide regulations, PREVENTICE aims to
continuously improve the design and the fitting of electromedical devices in order
to reduce as much as possible any negative impact on the environment caused by
the management of component parts, consumer materials, packaging and
discharge of devices when at their “end of life”.
Packaging materials were conceived and produced so as to allow the re-usage and
the salvage, including recycling, of most part of materials and to reduce the
quantity of garbage or residual products for discharge as much as possible. In
particular, packaging materials have been produced so as to limit the presence of
harmful metals and of other dangerous substances to minimum quantities in
emissions, ashes or lixiviation residual products. The total concentration levels of
heavy metals such as Lead, Cadmium, Mercury and hexavalent Chrome contained
in the packaging materials are in accordance with the limits established by the
directives in force related to this subject.
In order to cause minimum consequences to the environment, the design of the
device includes the highest possible miniaturization of the circuits, with the least
possible differentiation of materials and components, with a selection of
substances that guarantee the highest possibility to recycle and re-use the
components and to discharge them without risks for the environment.
The device is designed to guarantee the easy separation or disassembling of the
materials containing polluting substances from the others, in particular during the
operations of servicing and replacing parts. In particular, the largest plastic
components are marked according to their plastic contents in order to make it
easier to recycle the product.
ATTENTION
Please refer to local codes and regulations for proper disposal/recycle
requirements of packaging and consumer materials and of the device when at its
“end of life”.

Measures to be taken
Note 1: The floor should be in antistatic material (wood, ceramic, ect.). If covered by synthetic
material, relative humidity should be maintained at least at 30%.
Note 2: The quality of the electrical power supply and the mains frequency magnetic fields
should be typical of domestic, commercial and hospital environments.
Note 3: If the operator has to work without a break while power supply is interrupted, it is
necessary to have power supplied through a UPS (Uninterruptible Power Supply) unit.
1.10.1 RECOMMENDED DISTANCES FROM RADIOFREQUENCY (RF)
COMMUNICATION SYSTEMS
As stated in the chapter 1 “Information about safety” of this operator manual, it is
recommended to not use Radiofrequency (RF) transmission system near the
medical device. RF systems can cause interference which may cause instability
and interferences with the correct working of the equipment and it may alters the
signal acquired tracing.
The operator can prevent interference caused by electromagnetic field by
maintaining a minimum distance between the medical device and the RF
communication system being used (cell phones, mobile phones, etc,).
The following table shows the minimum distances in meters, according to the
maximum power at RF system output.

the transmitter, where P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
Note:
(1) at 80MHz and 800MHz, the separation distance for the higher frequency range applies.
(2) These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people
The operator must remember that the intensity of the electromagnetic fields
generated by fixed transmitters (radio-base stations for cellular or cordless phone,
TV and radio transmissions, amateur radio transmission, etc.) cannot be
predicated on theoretical basis.
Consequently, a direct measure may be necessary in the environment where is
used the medical device.
If the intensity of the electromagnetic fields exceeds that specified in the
immunity levels shown in the previous tables, and the medical device behaves
incorrectly working, additional measures may be necessary. I.e. orienting or
locating the medical device in a different way.

CHAPTER 3
POWERING UP THE DEVICE
The Bodyguardian Control Unit is powered through an internal battery. The
battery is rechargeable by means of the Bodyguardian Charging Cradle connected
to the mains trough the AC/DC power supply.
3.1 BATTERY CHARGING
While operating, if the Bodyguardian Control Unit detects that the battery level is
below a certain level (Low Battery Level as defined in the Preventice
Requirement Document) of the full capacity, LED 1 ( ) starts blinking with a
slow frequency, 1 second every 10 seconds, indicating that the device needs to be
recharged.
In this case, switch off Bodyguardian Control Unit and remove it from the strip
placed on the patient.
Additionally, if the Bodyguardian Control Unit detects that the battery level is
below a safety level (Critical Battery Level as defined in the Preventice
Requirement Document) of the full capacity, the Bodyguardian Control Unit starts
an automatic power off procedure to safely close the application and guarantee the
integration of the data sampled and stored up to that moment.
ATTENTION
If the device is not switched off manually by the user, when approaching a very low
battery level, the device will initiate an automatic power down procedures which
will allow uploading all the data acquired and safely switch off the device.
To recharge the Bodyguardian Control Unit place it on the Charging Cradle
according to the appropriate orientation (only one is possible due to the
mechanical constraints) and only after this operation connect the Charging Cradle
to the AC/DC Power supply and this last to the mains.
If the Bodyguardian Control Unit is properly placed and connected, the LED 1
( ) turns ON indicating that the device is charging. When the device battery
is fully charged the Led 1 turns OFF.
After the recharging operation is complete disconnect the AC/DC Power supply
from the mains and only after this operation remove the equipment from the
Charging Cradle.
