ELECTROMAGNETIC COMPATIBILITY (CONT)
Guidance and manufacturer’s declaration – electromagnetic immunity (cont)
The Hemo-Force® is intended for use in the electromagnetic environment specified below.
The customer or the user of the Hemo-Force® should ensure that it is used in such an
environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the Hemo-Force® , including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d = 1,2
d = 1,2 80 MHz to 800 MHz
d = 1,2 800 MHz to 2,5 GHz
Where P is the maximum output power rat-
ing of the transmitter in watts (W) according
to the transmitter manufacturer and d is the
recommended separation distance in meters
(m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey, should be less than the compliance
level in each frequency range.
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
•
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 electro-
magnetic site survey should be considered. If the measured field strength in the
location in which the Hemo-Force® is used exceeds the applicable RF compliance
level above, the Hemo-Force® should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the Hemo-Force® .
• Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3 V/m.
