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-FR302
is used exceeds the applicable RF compliance level above，the

JPD-FR302 should be observed to verify normal operation. If
abnormal performance is observed，additional measures may

be necessary，such as re-orienting or relocating JPD-FR302.
Over the frequency range 150 kHz to 80 MHz，field slrengths

should be less than 3V/m.

The Infrared Thermometer JPD-FR302 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-FR302 can help prevent
electromagnetic interference by maintaining a minimum

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.
