NOTE 1 At 80 MHz and 800 MHz,the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations.Electromagnetic is
affected by absorption and reflection from structures,objects and people.
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
asses the electromagnetic environment due to fixed RF
transmitters,anelectromagnetic site survey should be considered.If the measured

normal operation.If abnormal performance is observed,additional measures may
be necessary,such as re-orienting or relocating the Infrared Thermometer.Over
the frequency range 150 kHz to 80 MHz,field strengths should be less than 3

Recommended separation distances between portable and mobile
RFcommunications 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 infrared thermometer as
recommended below,according to the maximum output power of the
communications equipment.
