APPENDIX B: RF SEPARATION
The CritiCool
®
MINI and CliniLogger
™
are intended for use in an
electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the CritiCool
®
MINI and
CliniLogger
™
can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the CritiCool
®
MINI 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 CritiCool
®
MINI and CliniLogger
™
are given in Table 12.

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.
