The Allon
®
and CliniLogger™ are intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or the user of the Allon
®
and CliniLogger™ can help prevent
electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment
(transmitters) and the Allon
®
and CliniLogger™ as recommended below,
according to the maximum output power of the communications
equipment.
Recommended separation distances between portable and mobile
RF communications equipment and the Allon
®
and CliniLogger™ are
given in Table 17.

For transmitters rated at a maximum output power not listed in the table,
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:
At 80 MHz and 800 MHz, the separation distance
for the higher frequency range applies.
NOTE:
These guidelines may not apply in all situations.
Electromagnetic propagation is affected by
absorption and reflection from structures, objects
and people.
