Table 4. e FreeStyle Navigator system is intended for use in the electromagnetic environment specied below. e Customer or the user of the
FreeStyle Navigator system 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 Navigator, including cables, than
the recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended Separation Distance
d = 1.2 (m) @ 80 MHz to 800 MHz
d = 2.3 (m) @ 800 MHz to 2.5GHz
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).
Field strengths from 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: ese guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption and reection from structures,
objects and people.
a Field strengths from xed transmitters, such as base stations for radio (cellular /cordless) telephones and land mobile radios, amateur radio,
AM and FM radio broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to xed RF
transmitters, an electromagnetic site survey should be considered. If the measurement eld strength in the location in which the FreeStyle
Navigator system is used exceeds the applicable RF compliance level above the FreeStyle Navigator system 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
Navigator system.
b Over the frequency range 150kHz to 80 MHz, eld strengths should be less than 3 V/m.
