VitalConnect VitalPatch - Recommended Separation Distance

CorVitals, Distributor
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies. Note 2: These guidelines may not apply in all
situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects, and people.!
Note 3: UT is the a.c. mains voltage prior to application of the test level. (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 device is used exceeds the applicable RF compliance level above, the device
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the device. (b) Over the frequency range 150 kHz to 80 MHz, field
strengths should be less than 3 V/m.
Recommended separation distance between portable and mobile RF
communications equipment and VitalPatch!
(For ME equipment ME system that are not life-supporting)
The VitalPatch device is intended for use in the electromagnetic environment in which radiated RF disturbances are
controlled. The end user of the device can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the VitalPatch device as
recommended below, according to the maximum output power of the communications equipment.
Radiated RF
IEC 61000-4-3
10 V/m
80 MHz to
2.5 GHz
10 V/m
Portable and mobile RF communications equipment should be
used no closer to any part of the VitalPatch device than the
recommended separation distance calculated from the equation
applicable to the frequency of the transmitter. Recommended
separation distance:
80 MHz to 800 MHz
800MHz to 2.5 GHz
where P is the maximum output power rating of the transmitter in
watts (W) according to the transmitter manufacturer and d is the
recommended separation distance in meters (m).
