Operating Instruction TNI soft Flow 50 homecare system
Guidance and manufacturer’s declaration - electromagnetic immunity
The
TNI soft
Flow
50
is intended for use in the electromagnetic environment specified below. The customer
or the user of the "
TNI soft
Flow
50
" should assure that it is used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the
TNI soft Flow 50
, including
cables, than the recommended separation
distance caculated from the equation applica-
ble to the frequency of the transmitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz 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 rec-
ommended separation distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
survey,a should be less than the compliance
level in each frequency range.
b
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 “
TNI soft Flow 50
” is used exceeds the applicable RF compliance level
above, the “
TNI soft Flow 50
” should be observed to verify normal operation. If abnormal perfor-
mance is observed, additional measures may be necessary, such as reorienting or relocating the
TNI soft Flow 50
.
b Over the frequency range 150 kHz to 80 MHz, field strength should be less than 6 V/m.
