Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The SmarTRAC is intended for use in the electromagnetic environment specied below. The customer or
the user of the SmarTRAC 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 SmarTRAC,
including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance
d = 1.17 x P
d = 1.17 x P 80 MHz to 800 MHz
d = 2.33 x P 800 MHz to 2.5 GHz
where P is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufac-
turer and d is the recommended separation distance in
meters (m).
Field strengths from xed 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 to 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 pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to xed RF transmit-
ters, an electromagnetic site survey should be considered. If the measured eld strength in the location in
which the SmarTRAC is used exceeds the applicable RF compliance level above, the SmarTRAC should
be observed to verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as re-orienting or relocating the SmarTRAC.
b Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
