NOTES
U
T
is the a.c. supply voltage prior to the application of the test level
Note 1: at 80 MHz and 800 MHz, the separation distance for 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) 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 HiScan is used exceeds the applicable RF compliance level
above, the device should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating HiScan.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
5.3.3 RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE
AND MOBILE RF COMMUNICATION EQUIPMENT AND HISCAN
HiScan is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of HiScan can help preventing
electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and HiScan as
recommended below, according to the maximum output power of the
communications equipment.

For transmitters rates at maximum output power not listed above, the
recommended separation distance
d
in metres (m) can be estimated using the
equation applicable to the frequency of the transmitter, where
P
is the maximum
output power rating of the transmitter in watts (W) according to the transmitter
manufacturer.
