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 

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 
 Rechargeable Battery  Pack. The  rechargeable  battery  pack  installed  in  the 
equipment  contains  one  cell  that  is  not  accessible  to  the  user  and  its 
replacement should be  performed only by qualified personnel, authorized by 
PREVENTICE. Anyway, you should consider the following general warnings 
(e.g. in case of disposal of replaced parts with technical assistance). 
 Do not let the ends of the battery pack to come in contact with metal 
objects. 
 Keep away the battery pack from heat or flames. 
 Do  not  immerse  the  battery  pack  and  avoid  exposing  it  to  rain  or

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.
