Recommended Separation Distances for between
Portable and Mobile RF Communications Equipment and
the Tono-Pen AVIA Vet.
The Tono-Pen AVIA Vet is intended for use in the electromagnetic environment in which radi-
ated RF disturbances are controlled. The customer or user of the Tono-Pen AVIA Vet can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF Communications Equipment and the Tono-Pen AVIA Vet 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.
Note 3:
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80
MHz to 2.7 GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause
interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 has been
incorporated into the formula used in calculating the recommended separation distance for transmitters in these
frequency ranges.
