PillCam Capsule Endoscopy
228 Guidance and Manufacturer's Declarations
Recommended separation distances between portable and mobile RF communications
equipment and the PillCam capsules
The PillCam capsules are intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the PillCam capsules can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the PillCam capsules as
recommended below, according to the maximum output power of the communications
equipment.

10 Not applicable 3.8 7.3
100 Not applicable 12 23
For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be determined 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.
