Portable and mobile RF communication
equipment shall be used not closer to
any part of IR-FT Infrared Forehead
Thermometer, including cables, than the
recommended separation distance. The
distance shall be calculated according to
the formula applicable to the frequency

Interference may occur in the vicinity of
equipment marked with the following
symbols.
Note 1: At 80 MHz and 800 MHz, the formula used for higher frequency range applies.
Note 2: These guidances may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and human bodies.
