Recommended separation distances between portable and mobile RF
communications equipment and the TIE-210 Thermometer
The
TIE-210 Thermometer
is intended fo use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or the user of the
TIE-210 Thermometer
can help prevent
electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the
TIE-210 Thermometer
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 metres (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.
