Minimum separation distances between the Genius 3 and proximity fields
from RF wireless communications equipment found in the
New digital wireless technologies have been introduced in healthcare and various locations where medical electrical equipment
and systems are used. RF wireless communications equipment should be used no closer than the minimum separation distance
stated below when taking temperature readings with the Genius 3 thermometer.

* Values for minimum separation distance based on actual test data. Frequency and Maximum Power values were obtained from
Table 9 of IEC 60601-1-2:2014. The Genius 3 will maintain laboratory accuracy in its rated output range in accordance with ISO
80601-2-56:2017 when the minimum separation distance is met.
** The Genius 3 thermometer is not intended to be used in close proximity to 2-way radios and walkie-talkie radios commonly
used by personnel operating in emergency vehicles such as ambulances and helicopters. Using the Genius 3 near this type of
communication equipment can cause erroneous temperature readings.
Warning: Portable or mobile wireless RF communications equipment should be used no closer to the Genius 3 thermometer
than stated above. Otherwise, degradation of the performance of the Genius 3 could result.
If the Genius 3 thermometer is to be used near transmitters having maximum power other than the values listed in the table,
the separation distance can be calculated with the following equations:
For transmitters operating at frequencies within range 704 to 787 MHz: d =
For transmitters operating at frequencies within range 800 to 2570 MHz: d =
For transmitters operating at frequencies within range 5100 to 5800 MHz: d =
where d is the distance in meters and P is the transmitter power in Watts.
