Recommended separation distances between portable and mobile RF
communications equipment and the Infrared Body Thermometer.
The 4 in 1 contactless infrared body thermometer is intended for use in an
electromagnetic environment in which radiated RF disturbances are controlled.
The customer or user of the 4 in 1 contactless infrared body thermometer can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the 4 in 1
contactless infrared body 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:
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.
