Recommended Separation Distances Between Portable and Mobile RF
Communications and Adherus AutoSpray ET Dural Sealant
Adherus AutoSpray ET Dural Sealant is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or user of the Adherus AutoSpray ET Dural Sealant device can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Adherus AutoSpray ET Dural Sealant device 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.
