Recommended separation distances between portable and mobile RF
communications equipment and the SmartPill GI Monitoring System
The SmartPill GI Monitoring System is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the
user of the SmartPill GI Monitoring System can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the SmartPill GI Monitoring System 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 meters (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
manufact
urer.
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
p
eople.
