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.
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
considered. If the measured field strength in the location in which the
JPD-FR412 is used exceeds the applicable RF compliance level above,
the JPD-FR412 should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the JPD-FR412.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should
be less than 3 V/m.

The Infrared Thermometer JPD-FR412 is intended for use in an
electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Infrared Thermometer
JPD-FR412 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
