(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-FR202 is used exceeds
the applicable RF compliance level above, the JPD-FR202 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-FR202.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than 3 V/m.

The Infrared Thermometer JPD-FR202 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-FR202 can help
prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and
the Infrared Thermometer JPD-FR202 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
