RECOMMENDED SEPARATION DISTANCE BETWEEN PORTABLE AND MOBILE RF
COMMUNICATIONS EQUIPMENT AND THE DIGITAL EAR THERMOMETER
The digital ear thermometer is intended for use in an electromagnetic environment (for home healthcare)
in which radiated RF disturbances are controlled. The customer or the user of the digital ear thermometer
can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the digital ear 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reectionfrom
