Guidelines and manufacturer's declaration –
Resistance to emitted electromagnetic interference
The Chattanooga Intelect F-SW model is intended for operation in the electromagnetic environment
specied below. The customer or the user of the Chattanooga Intelect F-SW should ensure that it is used
in such an environment.

Electromagnetic environment – guidelines
Portable and mobile RF equipment should be used no
closer to any part of the Chattanooga Intelect F-SW,
including cables, than the recommended safety distance
calculated from the equation applicable to the frequency
of the transmitter.
Recommended safety distance:
Conducted RF
IEC 61000-4-6
3 V
rms
150 kHz to
80 MHz
3 V
rms
150 kHz to
80 MHz
d = 1.2√P
Radiated HF

according to
IEC 61000-4-3
3 V/m
80 MHz to
2.5 GHz
3 V/m
80 MHz to
2.5 GHz
d = 1.2√P
for 80 MHz to 800 MHz
d = 2.3√P
for 800 MHz to 2.5 GHz
Where P is the rated power of the transmitter in watts (W)
according to the transmitter manufacturer and d is the
recommended safety distance in metres (m).
The eld intensity of stationary radio transmitters, based
on an on-site inspection
a
, should be less than the
compliance level.
b
Interference may occur in the vicinity of devices 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 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 and TV broadcast cannot be
predicted theoretically with accuracy. To assess the electromagnetic environment with respect to xed
RF transmitters, an electromagnetic site survey should be considered. If the measured eld strength
in the location in which the Chattanooga Intelect F-SW is used exceeds the applicable HF compliance
level above, the Chattanooga Intelect F-SW should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the
Chattanooga Intelect F-SW.
b
Over the frequency range of 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
