ELECTROMAGNETIC COMPATIBILITY
Recommended separation distances between portable and mobile RF
communications equipment and the TS42S IR Thermometer
The TS42S IR Thermometer is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the TS42S IR
Thermometer can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
TS42S IR Thermometer 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
meters (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.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people
