9.3 Recommended Separation Distances
Recommended separation distances between portable and mobile RF communications
equipment and the FloPatch FP120
The FloPatch FP120 is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the FloPatch FP120 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and
the FloPatch FP120 as recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a 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.
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.
9.4 EMC Note:
If the FloPatch FP120 system is operated within the EMC environment described in Appendix C the device
will maintain essential performance and provide the following within specifications:
1. Doppler Audio and Waveforms Display
2. Calculated Metrics
3. Acoustic output
Operations in environments other than those specified in Appendix C may lead to a degradation in
performance which would manifest as a “stuttering waveform” and “stuttering audio.” It will be obvious
to the user when this occurs.
