a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be consid-
ered. If the measured field strength in the location in which the Non Contact Infrared Body
Thermometer is used exceeds the applicable RF compliance level above, the Non Contact
Infrared Body 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 Non Contact Infrared Body Thermometer.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
Recommended separation distances between portable and mobile RF communi-
cations equipment and the Non Contact Infrared Body Thermometer.
The Non Contact Infrared Body Thermometer is intended for use in an electromagnetic en-
vironment in which radiated RF disturbances are controlled. The customer or the user of the
Non Contact Infrared Body Thermometer can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equip-
ment (transmitters) and the Non Contact Infrared Body Thermometer as recommended be-
low, 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.
