c.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 transmitter, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the LIFEPAK 12 defibrillator/monitor system is used
exceeds the applicable RF compliance level above, the LIFEPAK 12 defibrillator/monitor system should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-
orienting or relocating the LIFEPAK 12 defibrillator/monitor system.
d.Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.

LIFEPAK 12 defibrillator/monitor system
The LIFEPAK 12 defibrillator/monitor system is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the LIFEPAK 12 defibrillator/
monitor system can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the LIFEPAK 12
defibrillator/monitor system as recommended below, according to the maximum output power of the
communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be determined using the equation applicable to the frequency of the
transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
Note 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
Note 2: The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795
MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
Note 3: An additional factor of 10/3 is used in calculating the recommended separation distance for transmitters
in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2.5 GHz to
decrease the likelihood that mobile/portable communications equipment could cause interference if it is
inadvertently brought into patient areas.
Note 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption
and reflection from structures, objects and people.
