FreeStyle Comfort
Guidance and Manufacturer’s Declaration–Electromagnetic Immunity
The FreeStyle Comfort is intended for use in the electromagnetic environment specified below. The customer or
the user of the FreeStyle Comfort 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
FreeStyle Comfort, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
P d 2 . 1

P d 2 . 1

= 80 MHz to 800 MHz
P d 2 . 1

= 800 MHz to 2700 MHz
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 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 FreeStyle Comfort
is used exceeds the applicable RF compliance level above, the FreeStyle Comfort should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the FreeStyle Comfort.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
