transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the Infrared Thermometer is
used exceeds the applicable RF compliance level above, the Infrared
Thermometer should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as
re-orienting or relocating the Infrared Thermometer.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.

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