Recommended separation distances between portable and mobile RF
communications equipment and the S3 MedSurg Bed.
The Epic II® Critical Careg Bed is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the Epic II® Critical Care Bed can help
prevent electromagnetic interferences by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Epic II® Critical Care Bed 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 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.
