17.3. Electromagnetic Immunity - for all Equipment and Systems that are not Life-supporting
Guidance and manufacture’s declaration – electromagnetic immunity
The HeraBEAT TM US device is intended for use in the electromagnetic environment specified below.
The customer or the user of the device should assure that it is used in such an environment
Immunity Test IEC 60601 test level Compliance level Electromagnetic environment – guidance

Portable and mobile RF communications equipment should be used no closer to
any part of the
HeraBEAT
TM
US device, including cables, than the recommended
separation distance calculated from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
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 metres (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic
site surveya, should be less than the compliance level in each frequency rangeb.
Interference may occur in the vicinity of equipment marked with the following
symbol:
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.
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
HeraBEAT
TM
US device is
used exceeds the applicable RF compliance level above, the HeraBEAT
TM
US device should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the HeraBEAT
TM
US device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
