The SmartBag System is fairly sensitive to
conducted and radiated RF. Disturbance
of the SmartBag System trace is possible
at and below the specified test level. It
may be necessary to relocate the
SmartBag System or to apply shielding.
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 800MHz, 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 SmartBag System is used exceeds the
applicable RF compliance level above, the SmartBag System should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the SmartBag System.
b)
Over the frequency range 80MHz to 6GHz, field strength should be less than 3V/m.
