Recommended isolation distance between portable and mobile RF communication devices and infrared forehead

thermometers

Infrared forehead thermometers are intended for use in electromagnetic environments where radiated RF

disturbances are controlled. According to the maximum output power of the communication equipment. Purchasers

or users of infrared forehead thermometers can prevent electromagnetic interference by maintaining a minimum

distance between portable and mobile RF communication equipment (transmitters) and infrared forehead

thermometers as recommended below.

For the rated maximum output power of the transmitters not listed in the table above, the recommended isolation

distance d, in meters (m), can be determined using the formula in the corresponding transmitter frequency column,

where p is the emission provided by the transmitter manufacturer Machine maximum output power in watts (w).

Note 1: At 80MHz and 800MHz frequencies, the higher frequency range formula is used.

NOTE 2 These guidelines may not be suitable for all situations. Electromagnetic propagation is affected by

absorption and reflection from buildings, objects and people.
