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-FR203 is used exceeds the applicable RF
compliance level above, the JPD-FR203 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-FR203.
b. Over the frequency range 150 kHz to 80 MHz, field strengths
should be less than 3 V/m.

The Infrared Thermometer JPD-FR203 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-FR203 can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communications
equipment
(transmitters)
and
the
Infrared
Thermometer JPD-FR203 as recommended below, according to the
maximum output power of the communications equipment.
