Recommended separation distance between portable and mobile RF communications equipment and the Alvita
Infrared Ear Thermometer
The Alvita Infrared Ear Thermometer is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The user of the Alvita Infrared Ear Thermometer can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Alvita Infrared 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
metres (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.
WARNING: The symbol on this product means that it’s an electronic product and
following the European directive 2012/19/EU the electronic products have to be dispose
on your local recycling centre for safe treatment.
